BACKGROUND & AIMS Downstream effects of muscarinic receptor stimulation in intestinal smooth muscle include contraction and intestinal transit. We thought to determine whether classic transient receptor potential (TRPC) channels integrate the intracellular signaling cascades evoked by the stimulated receptors and thereby contribute to the control of the membrane potential, Ca-influx, and cell r...

There is growing evidence that the host innate immune system has a critical role in regulating carcinogenesis, but the specific receptors involved and the importance of their interaction with commensal bacteria need to be elucidated. Two major classes of innate immune receptors, the Toll-like receptors and Nod-like receptors, many of which are upstream of nuclear factor-KB, are involved in the ...

Chavele et al. studied the role of the mannose receptor (MR) in crescentic nephritis. The accelerated nephrotoxic model of glomerulonephritis was induced on both wild-type (WT) and MR-deficient mice. The mice lacking the MR showed a markedly altered phenotype. They were largely protected against the development of glomerulonephritis with less affected glomeruli, less proteinuria and much better...

Background & Aims: Type 1 fimbriae is the most common adhesion factor in urine tract infection. In this Study, presence of virulence genes in isolated strains of uropathogenic E.Coli, O serotyping and molecular detection of phase variation of type 1 fimbriae were assessed during solid surfaces exposure. Methods: Isolated E.coli from urine samples of patients were serotyped by using serologic me...

Toll-like receptors (TLRs) are innate receptors critical for host defense, and play a role in normal biological processes. For example, host DNA, a TLR9 ligand, stimulates epithelial repair following skin wounding. TLR signaling also plays a crucial role in regulating intestinal homeostasis. We therefore asked whether TLR9 is important for intestinal wound repair using a dextran sulfate sodium ...

There is growing evidence that the host innate immune system has a critical role in regulating carcinogenesis, but the specific receptors involved and the importance of their interaction with commensal bacteria need to be elucidated. Two major classes of innate immune receptors, the Toll-like receptors and Nod-like receptors, many of which are upstream of nuclear factor-kappaB, are involved in ...

Modulating the activity of the endocannabinoid system influences various gastrointestinal physiological and pathophysiological processes, and cannabinoid receptors as well as regulatory enzymes responsible for the synthesis or degradation of endocannabinoids representing potential targets to reduce the development of gastrointestinal mucosal lesions, hemorrhage and inflammation. Direct activati...
