Molecular mechanisms regulating immune responses in thromboangiitis obliterans: a comprehensive review
Thromboangiitis obliterans (TAO) is a thrombotic-occlusive as well as an inflammatory peripheral vascular disease with unknown etiology. Recent evidence has supported the immunopathogenesis of the disease, however, the factors contributing to the altered immune function and vascular tissue inflammation are still unclear. This review was intended to collate the more current knowledge on the regu...
متن کاملProteomics and signal transduction in the crustacean molting gland.
Regulation of the molting cycle in decapod crustaceans involves 2 endocrine organs: the X-organ/sinus gland (XO/SG) complex located in the eyestalk ganglia and the Y-organ (YO) located in the cephalothorax. Two neuropeptides [molt-inhibiting hormone (MIH) and crustacean hyperglycemic hormone (CHH)] are produced in the XO/SG complex and inhibit ecdysteroidogenesis in the YO. Thus, YO activation ...
متن کاملImpacts of xenobiotics on crustacean molting: the invisible endocrine disruption.
Aquatic pollution has led to the accumulation of various xenobiotics in crustaceans. A number of these environmental chemicals have been found to interfere with molting of crustaceans. Results of initial mechanistic studies with Uca pugilator suggest that the disruption of molting results from the disturbance to the Y-organ-ecdysteroid receptor (EcR) axis by xenobiotics. Such disturbance to the...
متن کاملCyclic Nucleotides and Neuropeptide Signaling in the Crustacean Molting Gland Molting in decapod crustaceans is controlled by the eyestalk
Physiological processes are regulated by a diverse array of neuropeptides that coordinate organ systems. The neuropeptides, many of which act through G protein–coupled receptors, affect the levels of cyclic nucleotides (cAMP and cGMP) and Ca in target tissues. In this perspective, their roles in molting, osmoregulation, metabolite utilization, and cardiovascular function are highlighted. In dec...
متن کاملMolecular Mechanisms Regulating Macrophage Response to Hypoxia
Monocytes and Macrophages (Mo/Mɸ) exhibit great plasticity, as they can shift between different modes of activation and, driven by their immediate microenvironment, perform divergent functions. These include, among others, patrolling their surroundings and maintaining homeostasis (resident Mo/Mɸ), combating invading pathogens and tumor cells (classically activated or M1 Mo/Mɸ), orchestrating wo...
