The present invention relates to the field of neuronal health, neuronal protection and neuronal development. One embodiment of the present invention relates to compositions that can be used to treat or prevent delayed development of the enteric nervous system. Neuronal cells in the intestine can be protected. Their development/growth can be stimulated, for example, if neuronal delay should be restored. Disorders associated with delayed development of the enteric nervous system and/or with a damaged nervous system can be treated or prevented by the introduction contains lactoferrin compositions in accordance with the present invention.
The nervous system is a highly complex network of neurons and glial cells. It is present in all species of mammals. The nervous system consists of Central nervous system (brain and spinal cord) and peripheral nervous system (somatic, autonomic and enteric nervous system). Central nervous system controls cognitive functions (memory, attention, perception, activities, etc.)
Central nervous system controls cognitive functions (memory, attention, perception, activities, etc.). Together with the peripheral nervous system it plays a fundamental role monitoring of behavior. The somatic nervous system is responsible for coordinating movements of the body (under the control of consciousness). The autonomic nervous system maintains homeostasis activity of the body without mind control (heart beat rate, etc.). Finally, as the last part, the enteric nervous system that directly controls the gastrointestinal tract, such as intestinal barrier, motility, absorption, digestion and secretion, and participates thus in the protection of the intestine from any impacts and provides digestive comfort.
The nervous system develops during pregnancy and then in the postnatal period improved to a Mature functional state.
Immaturity or delay in maturation of the nervous system leads to the delayed formation of important biological functions it regulates. In particular, it leads to dysfunction of the intestine after birth, including low digestive/absorption capacity, gastrointestinal reflux, slow passage of bowel, a weakened intestinal barrier function, leading to food intolerances (respectively, to the necessity of parenteral nutrition support), discomfort in the intestines, accompanied with hard stools and increased risk of infection and Allergy.
The present invention was Ulu�stitching the state of the prior art and to provide an arrangement, based on natural ingredients, which help to maintain the development of the nervous system of the intestine and to protect her.
This problem is solved by the totality of essential features presented in the independent claims.
The authors of the present invention were able to show that lactoferrin, for example a composition comprising lactoferrin, can be used to support the development of neuronal cells and to protect them.
It was further shown that the introduction lactoferrin can increase the density of neurons and their survival.
Lactoferrin (LF), also known as lactotransferrin (LTF), is a globular multifunctional protein that you know is that it has antimicrobial activity and is part of the innate system of protection, primarily protecting the mucous membranes.
Lactoferrin can be found, for example, in milk and serum, and in many of the secretions of the mucous membranes, such as tears and saliva. Therefore, lactoferrin can be isolated, for example, from milk or you can get recombinant his way.
The present invention relates to lactoferrin, derived from any source.
For example, lactoferrin from milk or saliva has the advantage that it is a natural ingredient derived from mixtures of substances for food purity, and therefore it can be used as� in the form of enriched fractions of food composition without further purification.
The obtained recombinant lactoferrin way has the advantage that it can be easily obtained in high concentrations.
Colostrum contains relatively high concentration of lactoferrin, followed by human breast milk and cow's milk.
The authors present invention found that the lactoferrin or enriched with lactoferrin composition can be used to protect neuronal cells from degeneration. This degeneration can occur, for example, after stressful situations, such as acting on the fetus (vnutrimatocny) or newborn (hypoxia-ischemia at birth, oxygen therapy and hyperoxia, inflammation, need for parenteral support, etc.). It was shown that lactoferrin promotes the survival of neuronal cells and/or limits or prevents neuronal death of enteric neuronal cells and stimulates neuronal growth, which plays an important role, for example, in the development process.
In young children lactoferrin and/or containing lactoferrin composition of the present invention can be used to protect the enteric nervous system from any stress, for example, occurring during the period of neuronal development, and, consequently, to restrict and/or prevent stress induced growth retardation and is associated�'s with her bowel dysfunction.
In the context of the present invention, the term "children" includes infants and persons aged 0 to 14 years.
Infants aged less than 1 month are called newborns.
The term "newborn" includes premature infants, postmature children and full-term newborns. Under one year of age or begun to walk young children called toddlers or children who are able to walk (usually 12-36 months).
Lactoferrin and/or composition of the present invention can be entered, for example:
mothers during pregnancy and/or lactation,
- premature or full-term children with intrauterine growth retardation, which may occur as a result of any adverse processes during pregnancy (e.g., Smoking mother, his mother is taking drugs, poor quality of the placenta, abnormal location of the placenta, malnutrition of the mother or fetus, etc.)
- premature infants without fetal intrauterine growth,
- children with low/very low birth weight,
- when inorganic disorders successful development of children,
- any infants and children with growth retardation nervous system through, for example, hypoxemia-ischemia at birth or any other adverse processes and/or Liu�th infants and children with gastrointestinal dysfunction (impaired digestion, motor disorders, gastrointestinal reflux, slow passage of bowel intolerance of oral intake), with Hirschsprung's disease and inflammation affecting the gastrointestinal tract, such as necrotizing enterocolitis), with pathologies associated with obstruction.
Lactoferrin and/or composition of the present invention can be entered, thus, children and/or mothers during pregnancy and/or lactation.
Therefore, one embodiment of the present invention is a composition enriched with lactoferrin, for oral administration.
Enriched means that either lactoferrin added to the composition so that the resulting content in the composition is greater than the concentration of lactoferrin in the composition without the addition of lactoferrin, or that the composition is processed in such a way as to concentrate the natural content of lactoferrin in the composition.
Lactoferrin can be used as a pure compound.
In another embodiment, the lactoferrin may be used as enriched lactoferrin fraction, for example enriched with lactoferrin fraction of milk or whey.
As a source of milk or whey can be used, for example, cow's milk, human breast milk, goat's milk, camel's milk, Mare's milk and milk of a donkey. Can �be also used colostrum.
For therapeutic purposes the composition is administered in amounts sufficient to, at least, to cure or stop the symptoms of violations and/or its complications. Satisfy this condition number is defined as "therapeutically effective dose". Amounts effective for this purpose will depend on a number of factors known in the art, such as the severity of the violation, the weight and General condition of patient. In the preventive purposes of the composition of the present invention is administered to a patient, a part of the group at risk or subject to a violation in an amount sufficient to at least reduce the risk of violations. This amount is defined as a "prophylactically effective dose". In this case, the exact number also depends on the number of specific patient factors such as health status and weight of the patient.
Lactoferrin can be entered into the scheme of the present invention in a therapeutically effective dose and/or prophylactically effective dose.
Typical enriched with lactoferrin composition may contain lactoferrin in the amount of at least 1.6 g/L.

Group in position R1 may be identical or may differ from each other.
For example, sialic acid can be N-acetylneuraminic acid with R1=H, R2=N-acetyl and R3=N. In accordance with further embodiments of the present invention, sialic acid can be selected from the group consisting of 2-keto-5-atsetamido-3,5-dideoxy-d-glycero-d-galactouronic acid (Neu5Ac) and 2-keto-3-deoxy-d-glycero-d-galactono acid (KDN) or their mixtures.
Sialic acid used in the present invention contains N-acetylneuraminic acid, which has the following synonyms and abbreviations: o-Sialic acid; 5-atsetamido-3,5-dideoxy-D-glycero-D-galactosemia acid; 5-atsetamido-,5-dideoxy-D-glycero-D-galactosemia acid; Atsinanana acid; N-Acetyl-neuraminic; N-Acetyl-karamanova acid; NANA and Neu5Ac.
The most preferred lactoferrin-containing composition comprises sialic acid in an amount in the range from 100 mg/100 g (by weight) to 1000 mg/100 g (by weight) of the composition, for example in the range from 500 mg/100 g (by weight) to 650 mg/100 g (by weight) of the composition.
The composition of the present invention may, for example, contain at least about 0.001 wt.% sialic acids. In further embodiments of the present invention, the composition may contain at least about 0.005 wt.% or at least about 0.01 wt.% sialic acids.
In another embodiment, one or more lactoferrin-containing composition may contain iron in an amount in the range of from about 1 mg/100 g (by weight) to 100 mg/100 g of the composition, for example 10 mg/100 g (by weight) to 30 mg/100 g of composition.
One lactoferrin-containing composition may contain, for example, approximately 852 mg/100 g (by weight) of sialic acid and 22 mg/100 g (by weight) of iron.
Lactoferrin-containing composition of the present invention may have a caloric/energy value in the range of 30 kcal/100 g to 1000 kcal/100 g of composition, preferably from 50 kcal/100 g to 450 kcal/100 g of composition. It may, for example, have Kalo�inost approximately 400 kcal/100 g.
Type of composition privately is not limited. It is preferably a composition for oral or enteral administration.
The composition may, for example, be selected from the group consisting of food products, products for animals, pharmaceutical compositions, nutritional formulations, nutraceuticals, drinks, food supplements and infant formula.
In one typical embodiment of the present invention, the composition comprises a protein source, a source of lipids and a source of carbohydrates.
The composition contains a protein source that may be present in the range between 1.4 and 100 g/100 kcal, preferably between 2 and 6.0 g/100 kcal of the composition. Since lactoferrin is a protein, it should be considered part of the protein source.
The type of protein is not considered critical to the present invention. For example, you can use the protein sources based on whey, casein, or their mixtures. As for whey protein, you can use acid whey, sweet whey or mixtures thereof, as well as alpha-lactalbumin and beta-lactalbumin in any desired proportion. Whey protein can be modified whey. Sweet whey is a readily available by-product of cheese production and is often used�ized in the production of infant formula based on cow's milk. However, sweet whey includes a feature called caseino-Glyco-macropeptide (CGMP), which is rich in threonine and poor in tryptophan, which is undesirable. Removing CGMP from sweet whey makes the content of threonine closer to breast milk. This modified sweet whey can then be supplemented with those amino acids, the contents of which are small (mainly histidine and tryptophan). The process of removing CGMP from sweet whey is described in EP 880902, and children nutrient mixture on the basis of such a modified sweet whey is described in WO 01/11990. Proteins can be intact or hydrolyzed herbal fibers, or be a mixture of intact and hydrolyzed proteins. It may be desirable to use a partially hydrolysed proteins (degree of hydrolysis between 2 and 20%), for example, for persons who have a suspected risk of developing allergies to cow's milk. If you require hydrolysed proteins, the hydrolysis can be performed at will and according to the known technique. For example, hydrolyzed whey protein may be prepared by enzymatic hydrolysis of whey fraction in two stages, as described in EP 322589. To obtain intensely hydrolyzed protein whey proteins may be subjected to triple hydrolysis using Alcalase 2.4 L (EC 940459),�eat Neutrase 0.5 L (obtainable from Novo Nordisk Ferment AG), and then Pancreatin at 55°C. If the whey fraction used as the starting material, contains almost no lactose, it is shown that in the process of protein hydrolysis is significantly lower, and the blocking of lysine. This reduces the blocking of lysine in approximately 15% of the total weight of lysine to less than about 10% by weight of lysine; for example about 7% by weight of lysine, which greatly improves the nutritional value of a protein source.
It is known that whey proteins provide a number of benefits for health. The protein fraction in whey (approximately 10% of the total weight of solids of the whey) contains several protein fractions, such as beta-lactoglobulin, alpha-lactalbumin, bovine serum albumin and immunoglobulins. In one embodiment at least 50%, preferably at least 75%, even more preferably at least 85% by weight of the protein source is whey protein.
The compositions of the present invention may contain a source of lipids. The source of the lipid can be any lipid or fat. Preferred sources of fat include milk fat, palm olein, sunflower oil with high content oleinu. Can also be added essential fatty acids Lineva acid and alpha-linolenic �Isleta, and also by small amounts of oils containing many converted arachidonic acid and docosahexaenoic acids, such as oils from fish or from microorganisms. The source of lipids is preferably the ratio of fatty acids n-6 to n-3 is equal to from about 5:1 to about 15:1; for example from about 8:1 to about 10:1.
In the presence of a source of lipids it may be responsible for 30-50% of the total energy value of the composition.
The compositions of the present invention may contain a source of carbohydrates. Can be used any source of carbohydrates, such as lactose, saccharose, maltodextrin, starch and mixtures thereof.
The source of carbohydrates may be responsible for 35-65% of the total energy value of the composition.
For example, the composition of the present invention may contain protein in the range from about 1.8 to 3.0 g/100 kcal, lipids from about 4.4 to 6.5 g/100 kcal and/or carbohydrates from approximately 60 to 75 g/100 kcal.
The compositions of the present invention may also contain all vitamins and minerals, for which it is established that their presence in quantities that are significant for the power needed in a daily diet. Minimum requirements have been established for certain vitamins and minerals.

For this purpose, can also be used N-acetylgalactosamine transferase and/or N-acetylglycine transferase. N-acetylated oligosaccharides can also be formed by the technique of fermentation with the appropriate enzymes (recombinant or natural) and/or microbial fermenting. In the latter case microbes may either Express their natural enzymes and substrates, or may be formed so as to make the respective substrates and enzymes. Can be used odnomikronnoye culture or mixture of cultures. The formation of N-acetyl�separate oligosaccharide can be initiated by acceptor substrates, starting with any degree of polymerization (DP) from DP=1 and next. Another option is the chemical transformation of ketohexose (e.g., fructose), loose or related oligosaccharide (e.g. lactulose) in N-acetylgalactosamine or N-acetylhexosamines containing oligosaccharide, as described in Wrodnigg, T. M.; Stutz, A. E. (1999) Angew. Chem. Int. Ed. 38:827-828.

The compositions may optionally contain other compounds that may have positive effects, such as nucleotides, nucleosides, and the like.
For use according to the invention compositions, such as baby formula, can be prepared by any suitable method. For example, you can prepare baby formula, mixing in appropriate proportions protein source, a carbohydrate source and a fat source. Optionally, the mixture can include emulsifiers. At this stage you can add the vitamins and minerals that are usually added later to avoid thermal degradation. All of lipophilic vitamins, emulsifiers, etc. before mixing can be dissolved in fat. Then, the liquid mixture can be added to water, preferably water, under�ergota reverse osmosis. Then, the liquid mixture may be subjected to heat treatment to reduce bacterial contamination. For example, the liquid mixture may be rapidly heated to a temperature in the range of from approximately 80°to approximately 110°C for from about 5 seconds to about 5 minutes. This can be accomplished by steam injection or by heat exchanger; for example a plate heat exchanger. Then, the liquid mixture can be cooled to from about 60°to about 85°C; for example, pulsed cooling. The liquid mixture may then be homogenized; for example in two stages from about 7 MPa to about 40 MPa in the first stage and about 2 MPa to about 14 MPa in the second stage. Then homogenisierung the mixture may be further cooled to add any temperature-sensitive components; such as vitamins and minerals. The pH and the solids content of the homogenized mixture is convenient to standardize at this point. Homogenized mixture is transferred to a suitable drying apparatus such as a spray drier or freeze drier and converted to powder. This powder should contain not more than 5% by weight of moisture. If you want to add a probiotic(s), they should be cultured in any suitable manner and �podgotovitj to adding to child nutrition, for example, by freeze drying or spray drying. Alternatively, bacterial preparations can be bought from specialist suppliers such as Christian Hansen and Morinaga, already prepared in a suitable form for adding to children's nutrient mixture. Such bacterial preparations can be added to powdered infant mixture by dry mixing.
Lactoferrin can be added at any stage of this procedure, but preferably after the heating stage.
The present invention expands the use of lactoferrin for preparing a composition for the treatment or prevention of a delay in the development of the enteric nervous system and/or preventing gastrointestinal disorders associated with a delay in the development of the enteric nervous system and/or damaged enteric nervous system.
Lactoferrin or a composition according to the present invention can also be used to repair damaged enteric nervous system.
Disorders associated with a delay in the development of the enteric nervous system, and/or impaired enteric nervous system include, for example, reduced digestive or adsorption capacity, gastrointestinal reflux, slow the rate of passage of the intestine, a weakened intestinal barrier function, the neper�nosimost enteral nutrition, discomfort in the intestines, solid chair.
In another embodiment of the present invention, the composition comprising Lactoferrin, can be used to treat or prevent delayed neuronal migration.
The composition of the present invention can be used to enhance neuronal density and/or neuronal survival.
For the purposes of this invention it is essential that the composition contain lactoferrin or a connection that turns into lactoferrin after administration. The composition should not be enriched with lactoferrin, although this may be preferred, since in this case a greater amount of lactoferrin can be injected in smaller volumes.
Lactoferrin can be used for the preparation of any of the compositions. However, preferably, the lactoferrin was received in the form of a composition corresponding to that described above.
To achieve this, the composition can be administered to mothers during pregnancy, mothers during lactation, premature or full-term infants, children with intrauterine growth retardation, infants, children and adolescents.
Experts will understand that it is easy to combine all of the features of the present invention, without departing from the claims of the invention described. In particular, features described for the use of this invented�I, can be attributed to the composition of the present invention and/or lactoferrin and Vice versa.

t-test student t-test was used to compare the differences of mean values between one control reference population, and average values for all other processing conditions in each group.
Were checked the following concentration-enriched lactoferrin fraction of cow's milk: 1 µg/l 10 µg/l 100 µg/l 1 mg/l 10 mg/l 100 mg/l and 1 g/l was performed as positive control (CNTF, ciliary necrotrophy factor, 100 ng/ml), a well-known necrotrophy factor is that earlier it was reported that it induces naranya processes in different populations neurone� (Oyesiku and Wigston, 1996 (Oyesiku NM, Wigston DJ: Ciliary neurotrophic factor stimulates neunte outgrowth from spinal cord neurons. J Comp Neurol 1996; 364: 68-77). Basal controls included untreated cells. The results are shown in figure 1.
Protection of neuronal cells from stress
Primary rat cultures of enteric neuronal cells were seeded into the cells and were incubated with different concentrations of enriched lactoferrin fraction of cow's milk within 48 hours. After triple washing with phosphate-saline buffer solution (sterile PBS, 37°C) cells were incubated for 12 hours in cell medium without lactoferrin containing H2O2or vector (control). The protective effects of lactoferrin against induced H2O2the death of neuronal cells was evaluated by measuring the release of neuron-specific enolase (NSE) in a cellular environment. After oxidative stress environment of different groups were collected and centrifuged for 10 min at 12000 revolutions per min (4°C). Collected supernatant was determined NSE released into the culture medium, Immunoradiometric method. The results were expressed in ng/ml As shown in Figure 2, H2O2induced a significant increase of NSE in the medium (p<0,05, n=8). As shown in figure 2, treatment of primary neuronal enteric cells fraction enriched with lactoferrin significantly reduced the H2O2-ind�caravanne the release of NSE (p< 0,05, n=8).
The neuroprotective property of lactoferrin from cow's milk was confirmed using a neuronal-like cell line (neuroblastoma cells SH-SY5Y). Briefly, cells SH-SY5Y were seeded for 24 hours in culture medium was enriched with added lactoferrin fraction at different concentrations for 48 hours. Directly to the cell medium was added for 6 hours (H2O2or vector (control). Cells, in the end, washed with 0.1 M PBS and then collected using trypsin - EDTA. The cell suspension then was combined with the supernatant and centrifuged for 5 min at 2000 rpm. After centrifugation the precipitate was resuspended in 500 ál of 0.1 M PBS. Membrane permeability was assessed using flowcytometry, using as a fluorescent marker 7-AAD. To do this, 200 µl of the cell suspension were incubated for 10 min with 7-AAD prior to the collection using the Bioanalyzer BD FACS Array™. Flowcytometric study using 7-aminoantipyrine D (7-AAD) allowed to distinguish live (7-AAD negative) cells (7-AAD positive) SH-SY5Y cells at late stage of apoptosis/necrosis in response to oxidative stress. The results presented in Figure 3, expressed in % 7-AAD positive cells relative to total number of cells. As shown in Figure 3, H2O2induced mean�diesel increase the percentage of 7-AAD positive cells (p< 0,05, n=6). As shown in figure 3, treatment of cells SH-SY5Y by lactoferrin reduced the H2O2- induced increase in the percentage of 7-AAD positive cells.
Lactoferrin increases the density of neurons and their survival. It protects neuronal cells and inhibits neuronal cell death.
After receiving the results of performed a morphological study. Closely spaced slices of the dorsal and lateral hippocampus at the level of striatum was prepared for assessing the architectonics of the cerebral cortex and hypothalamus and white matter lesions of the brain. Specific cell types were labeled immunochemical to assess specific cellular responses. Performed specific labeling of neurons (NeuN), astrocytes (GFAP) and radial glia (Nestin) in combination with markers of myelination (MBP). Briefly, the method was as follows.
On the 7th (P7) and 21 (P21) postnatal day, respectively, in rat pups from each group were subjected to deep anesthesia using ketalar (50 mg/ml; 0.2-0.5 ml, intraperitoneal (i.p.)). Animals were perfesional intracardiac 0.9% NaCl followed by 4% paraformaldehyde. Removed the brain, weighed it and fixed overnight in 4% paraformaldehyde, then at least 24 hours in 30% sucrose and stored at -80°C until preparation of slices. Coronal sections (10 μm) at the level of the dorsal hippocampectomy on a cryostat (Microm Cryo-Star HM 560M, Microm International, Germany). Each animal received three of the slices at intervals of 200 μm.
Immunohistochemistry: brain tissue was processed to study the immune response against MBP (1:400 mark, city, country (brand city country), using the avidin-Biotin peroxidase complex (ABC; Vector Laboratories, Burlingame, CA, USA). Sections were blocked in 4% bovine serum albumin (BSA brand, city, country), then incubated with primary antibody for 24 h at 4°C, then incubated with secondary antibody (1:200 brand city country), then with a complex of avidin-Biotin (1:200, Vector Laboratories, Burlingame, CA, USA). The reaction was carried out slices with the Chromogen 3,3-diaminobenzidine (DAB brand, city, country) in 0.01% hydrogen peroxide, and then placed under a coverslip.
The same Protocol was used for fluorescent immunohistochemistry nestin (1:500 mark, city, country), GFAP (1:400 mark, city, country) and NeuN (1:200 mark, city, country), except for sections that are not incubated in a complex of avidin-Biotin and DAB.
All experimental groups and their corresponding controls were stained simultaneously. If the processing of the primary antibody was absent, staining occurred.
Quantitative analysis was performed using MetaMorph® imaging system (Meta Imaging Software, Molecular Devices Corporation, Pennsylvania, U. S. A). Values for each animal were combined and calculated CP�the found value is the average±SEM for each group. The measurements were performed on coded glasses that are unknown to the observer, and the codes were not revealed until the analysis is complete. The obtained results are shown in figure 4.
Histological analysis showed that the addition of lactoferrin (LF) Dex pup (n=2) significantly increased the morphology of the nuclei and the density of neurons in the CA2-CA3 field of hippocampus compared with 7-day control rats (Dex control pup at P7). The decrease in the density of neurons in the cortex on day 7 after birth involves the loss of neurons. The density of neurons is similar to the normal control group treated with the carrier (Figure 4). Lactoferrin obtained in this certain time interval of development, will affect the density of neurons in hippocampus and in an area with high sensitivity to lack of nutrition and dependent stress anomalies. This means that the introduction of LF increases the density of neurons and their protection, for example, in young rats retarded (IUGR).
The addition of lactoferrin reduces the expression of genes SOX10 and CRHbp colon on the 21st day after birth.
Collected tissues of the colon of rats treated with dexamethasone and treated or not with oral lactoferrin supplements or control isonitrogenous mixture of amino acids in the process of lactation to the 21st postnatal day. Was extracted with the total RNA content using.�and TriPure. 0.5 μg of RNA (RNA) was subjected to reverse transcription using oligo-dT and Superscript kit and performed real-time polymerase chain reaction (PCR) (Applied Biosystem, TaqMan PCR 7900 HT). Representing the genes of interest were normalized to the constitutive expression of the gene 18S. After normalization we calculated the percentage of difference between the two groups (expressed in percent, n=6). The results showed that the expression of the SOX10 gene in the group of rats treated with Lactoferrin, was reduced by 30% compared with the control group. SOX10 is a marker of glial and neuronal progenitor cells (Wegner M, Stolt CC. From stem cells to neurons and glia: a Soxist''s view of neural development. Trends Neurosci 2005 25(11):583-8; Young et al., Acquisition of neuronal and glial markers by neural crest-derived cells in the mouse intestine, The Journal of Comparative Neurology 2003 456:1-11). It is present in large quantities in the embryonic stages and the initial phases of postnatal development, and its expression then decreases during the ripening process. Our results suggest a better maturation of neuronal progenitor cells to the stage of Mature/differentiated neuronal cells of the enteric nervous system in lactoferrin group on the 21st day of postnatal development. Our results also show a 60% decrease in expression in colon gene hormone-binding protein, corticotropin releasing (CRHbp), lactoferrin group compared with �ontroller. Binding to corticotropin releasing hormone (CRH), CRHbp limits the availability of free and active CRH and thereby reduces its stimulating effect on the motility of the intestine (Saesholtz et al., Mouse models of altered CRH-binding protein expression. Peptides 2001. 22(5):743-51). Observed in our study 60% reduction in the expression of CRHbp gene may contribute to the increase of free and active CRH in the large intestine, the availability of which can stimulate the function of the motility of the intestines in these immature rat pups.
