... cytokine-induced secretion of prostaglandin E2 (PGE2). This inhibitory action has been associated with reduced expression of COX-2, without modulating COX-1 expression. This mechanism is associated with VA-induced destabilization of COX-2 mRNA, thereby depleting the functional COX-2 mRNA available...

... Abstract Maintenance of a film of saliva on oral surfaces is dependent upon nerve-mediated, reflex salivary gland secretion. Afferent signalling arises from taste, olfaction and mastication and is modified by signalling from other centres in the central nervous system before efferent signals...

... Abstract The role of amino acids in the regulation of insulin secretion has received relatively little attention because of the clinical and basic science focus on glucose and, more recently, on fatty acids as the essential determinants of this process. However, early clinical observation...

... design, flagellar and non-flagellar Type III secretion systems instead provideexcellent case studies in the evolution of complex systems from simpler components. ...

... Abstract In general way cell swelling evokes and shrinking inhibits exocytosis of proteins andpeptides stored in secretory vesicles from various types of cells. Dynamics of this typeof hormone secretion is indistinguishable from that induced by specific secretagogue.Peculiarities of swelling...

... Abstract Ghrelin, a peptide predominantly produced by the stomach, has been discovered as naturalligand of the GH secretagogue (GHS) receptor type 1a (GHS-R1a), suggesting the existencea new endogenous modulator of somatotrope secretion. Subsequently, ghrelin turnedout to exert pleiotropic...
