Intestinal glucose sensing and regulation of intestinal glucose absorption.
SGLT1 (Na(+)/glucose co-transporter 1) transports the dietary sugars, D-glucose and D-galactose, from the lumen of the intestine into enterocytes. SGLT1 regulation has important consequences for the provision of glucose to the respiring tissues and is therefore essential for maintaining glucose homoeostasis. SGLT1 expression is directly regulated in response to changes in the sugar content of t...
متن کاملThe study of microanatomy of intestinal epithelium in the Chinese soft-shelled turtle (Pelodiscus sinensis)
The microanatomy of the intestinal epithelium in the Chinese soft-shelled turtle (CST) was studied by light and transmission electron microscopy (TEM). The small intestinal epithelium (SIE) was single layered or pseudostratified. The enterocytes contained mitochondria or mitochondria and lipid droplets. The enterocytes were arranged tightly in the apical parts of epithelium and connected by des...
متن کاملMicrobial Sensing by the Intestinal Epithelium in the Pathogenesis of Inflammatory Bowel Disease
Recent years have raised evidence that the intestinal microbiota plays a crucial role in the pathogenesis of chronic inflammatory bowels diseases. This evidence comes from several observations. First, animals raised under germ-free conditions do not develop intestinal inflammation in several different model systems. Second, antibiotics are able to modulate the course of experimental colitis. Th...
متن کاملNonruminant Nutrition Symposium: intestinal glucose sensing and regulation of glucose absorption: implications for swine nutrition.
The Na(+/)glucose cotransporter (SGLT1) is the major route for the transport of dietary sugars from the lumen of the intestine into enterocytes. Regulation of this protein is essential for the provision of glucose to the body and avoidance of intestinal malabsorption. This has important nutritional implications in particular for young and growing animals. It has been demonstrated that dietary s...
متن کاملThe Role of SGLT1 and GLUT2 in Intestinal Glucose Transport and Sensing
Intestinal glucose absorption is mediated by SGLT1 whereas GLUT2 is considered to provide basolateral exit. Recently, it was proposed that GLUT2 can be recruited into the apical membrane after a high luminal glucose bolus allowing bulk absorption of glucose by facilitated diffusion. Moreover, SGLT1 and GLUT2 are suggested to play an important role in intestinal glucose sensing and incretin secr...
