Structural organization of enteric nervous system in human colon.
The organization of the Enteric Nervous System (ENS) was studied in the human colon. Fragments of the whole colonic wall were either routinely processed or Zinc-Iodide Osmium impregnated. Single-layer preparations were also obtained from some of the Zinc-Iodide Osmium-impregnated specimens. The results showed some differences in the organization of human colonic ENS from that of other mammals. ...
متن کاملThe enteric nervous system.
T HE enteric nervous system is a collection of neu-rons in the gastrointestinal tract 1 that constitutes the " brain of the gut " and can function independently of the central nervous system. 2 This system controls the motility, 3,4 exocrine and endocrine secretions, 5 and microcirculation 6 of the gastrointestinal tract; it is also involved in regulating immune and inflammatory processes. 7 In...
متن کاملThe human enteric nervous system.
Decades of work in animal models have demonstrated that the enteric nervous system (ENS) plays a key role in controlling gut functions. Recent advances made it possible to extend such studies to the ENS of man in health and even in disease. Such studies have already provided new insights into the pathophysiology of inflammatory and possibly functional bowel diseases. Studies on human ENS reveal...
متن کاملCharacterization of retinaldehyde dehydrogenase 3 Caroline
RALDH3 (retinal dehydrogenase 3) was characterized by kinetic and binding studies, protein engineering, homology modelling, ligand docking and electrostatic-potential calculations. The major recognition determinant of an RALDH3 substrate was shown to be an eight-carbon chain bonded to the aldehyde group whose kinetic influence (kcat/Km at pH 8.5) decreases when shortened or lengthened. Surprisi...
متن کاملThe timing and location of glial cell line-derived neurotrophic factor expression determine enteric nervous system structure and function.
Ret signaling is critical for formation of the enteric nervous system (ENS) because Ret activation promotes ENS precursor survival, proliferation, and migration and provides trophic support for mature enteric neurons. Although these roles are well established, we now provide evidence that increasing levels of the Ret ligand glial cell line-derived neurotrophic factor (GDNF) in mice causes alter...
