Immunophysiology of the Gut

Bristol-Myers Squibb/Mead Johnson Nutrition Symposia, Volume 11: Immunophysiology of the Gut represents a comprehensive and systematic coverage of the immunophysiology of the gut, compiling research that integrates the mucosal immune system and intestinal physiology.

This book discusses the immunological regulation of epithelial function, fibroblastic sheath, pathways of arachidonic acid metabolism, and gastric response to mucosal anaphylaxis. The implications for inflammatory diarrhea, role of breast milk in neonatal host defense, and milk-borne peptide growth factors in human and bovine milk are also elaborated. This publication likewise covers the immunopathologic features of celiac disease, immune responses in protein-energy malnutrition, and bacterial translocation.

This volume is suitable for experts and clinicians from the disciplines of mucosal immunology, intestinal physiology, and enteric neurophysiology.
