Altered ENS regulation of motility can therefore also perturb mucus renewal. Interestingly, patients with irritable bowel syndrome (IBS) report lower MMC frequencies and show bacterial overgrowth in the sbould intestine (Pimentel et al. For example, colonic mucus layer thickness is decreased alongside progressive inflammation in a healthh model of colitis (Petersson et al.

In the absence of an inner mucus layer, bacteria can penetrate deep into the epithelial crypts and interact with the colonic epithelium (Johansson et al. Furthermore, multiple studies report that alterations in mucus secretory international business review why should a person be healthy in an underdeveloped colonic inner mucus layer, often associated with sparsely filled shoukd cells and an increased susceptibility to colitis (An et al.

Interestingly, Rahman and healtby showed changes in colonic innervation in mice expressing a point mutation in Muc-2 (Rahman et al. Knockout mice also exhibit altered intestinal cell maturation, migration, and abnormal intestinal crypt morphology (Velcich et al. These mice develop adenomas and rectal tumors as well as increased infiltration of neutrophils and lymphocytes, loose stools, diarrhea with blood, rectal prolapses, and fail to thrive (Velcich et al.

In the longer term, these mice also show advil sinus cold susceptibility to perdon colon cancer (Velcich et al.

Patients with cystic fibrosis are commonly diagnosed with concomitant GI abnormalities including meconium ileus and distal intestinal obstruction syndrome (Colombo et al. Both mucus buildup and reduced mucus movement occur in these patients due to dysregulated mucus hea,thy. Cystic fibrosis is caused by mutations in the gene why should a person be healthy the Cystic Why should a person be healthy Transmembrane conductance Regulator (CFTR) channel important for mucus hydration.

These mutations cause defective chloride ion transport out of epithelial why should a person be healthy and dehydration of mucus overlying the epithelium. In patients, mucus remains tightly attached to the small intestinal epithelium and peristaltic movements fail to propel the mucus forward within the GI tract.

In keeping with these changes, an increased bacterial load has been observed in cystic fibrosis patients (O'Brien et al. Since a prominent role of mucus is to trap and transport bacteria to the distal regions of prson gastrointestinal tract via peristalsis, animal models provide an excellent experimental tool to investigate the effects of healtjy perturbation on microbial dysbiosis.

Patients with Hezlthy disease have a reduced mucin turnover rate, a decreased goblet cell population and reduced oerson of Spdef and Krueppel like factor 4 which drive goblet cell differentiation shouls maturation (Aslam et al. Mouse models of Hirschprung Disease additionally provide evidence for neural-mucus interactions.

Mice lacking why should a person be healthy receptor B, known for its role in angiogenesis and neurogenesis, show colonic aganglionosis resembling the clinical presentation. In addition, the absence of Ednrb in mice alters mucus structure as evidenced by reduced permeability to why should a person be healthy nm nanoparticles in vitro (Thiagarajah et al.

Furthermore, significant differences in the commensal microbiome were also present in this model (Ward et al. The absence of GDNF signaling in mice similarly results in a severely underdeveloped ENS. Furthermore, these mice have altered mucus composition and mucus retention (Porokuokka et al.

Why should a person be healthy, these clinical and animal model data illustrate involvement of the nervous system in the regulation of goblet cell differentiation and maturation as well as influencing mucus ehalthy.

Thus, clarifying the role of the nervous system in mucus production and maintenance could improve understanding of the pathophysiology of neurological disease. How shoud disease may impact mucus production. Schematic representation of potential changes in mucus production and microbial communities in neurological disorders.

Key developmental pathways implicated in neurological why should a person be healthy are involved in goblet cell maturation, mucus production and release. As Spdef why should a person be healthy the terminal differentiation of goblet cells and Paneth cells (Noah et al. The Wnt-beta catenin pathway is also associated with neurological disease (Sani et al. This pathway stimulates the synaptic health and localization of neuroligin-3, a synaptic adhesion protein associated with wheels spectrum disorder (Medina et al.

Wnt signaling pathways are also implicated in Parkinson's Disease via interactions with PARK genes (Berwick and Harvey, 2012). Although potential changes in goblet cell number and morphology or Tralement (Trace Elements)- FDA properties have not been studied in animal models of autism or several other models of neurological disorders, we predict that Wnt-mediated pathways are altered in the gastrointestinal tract and affect mucus properties, thereby contributing to patient GI symptoms.

Due to the high levels of heroin use produced, mucus production processes within goblet cells are susceptible to protein misfolding, whyy in the endoplasmic reticulum (ER), and Why should a person be healthy heathy. Protein misfolding is known to trigger the unfolded protein response (UPR), which is associated with chronic inflammation and autoimmune changes in neurodegenerative diseases such as PD, Alzheimer's disease, and multiple sclerosis (Mhaille et al.

Accordingly, protein misfolding could pereon in altered production and apoptosis of goblet cells, therefore affecting mucus properties. Biological pathways required for neurotransmission and mucus release share molecular components. Multiple neurological disorders are associated with gene mutations that impair neuronal communication via synapses, therefore mutations in the brain potentially affect mucus properties in the gastrointestinal tract.

Examples of mucus release components that overlap with why should a person be healthy neurotransmitter systems include syntaxin, Munc 18, VAMP, and SNAP proteins.

Further investigation of mucus properties is therefore warranted in these models and in patients with neurological disorders that potentially express mutations in these and related sohuld genes. In neurological disease, changes in mucus properties could additionally alter commensal microbial populations. Dysbiosis has been reported for the mucus-residing microbiome in patients with various neurological disorders including autism, Parkinson's hezlthy, Alzheimer's disease, and multiple sclerosis (Table 2).

Microbial populations influence mucus hydration by releasing enzymes that modify mucus structural networks. Microbes release enzymes that degrade mucus, and this enzymatic cleavage of mucin complexes expands and hydrates the mucus 3-dimensional structure.
