The hallmark of human Mycobacterium tuberculosis infection is the presence of lung granulomas. Lung granulomas can have different phenotypes, with caseous necrosis and hypoxia present within these structures during active tuberculosis. Production of NO by the inducible host enzyme NOS2 is a key antimycobacterial defense mechanism that requires oxygen as a substrate; it is therefore likely to pe...
Proteases have been considered as an important group of targets for development of antiprotozoal drugs due to their essential roles in host-parasite interactions, parasite immune evasion, life cycle transition and pathogenesis of parasitic diseases. The development of potent and selective serine protease inhibitors targeting L. donovani secretory serine protease (pSP) could pave the way to the ...
Mast cell (MC) granules contain large amounts of proteases of the chymase, tryptase and carboxypeptidase A (MC-CPA) type that are stored in complex with serglycin,a proteoglycan with heparin side chains. Hence, serglycinprotease complexes are released upon MC degranulation and may influence local inflammation. Here we explored the possibility that a serglycin-protease axis may regulate levels o...
the present study was conducted to evaluate the effect of dietary inclusion of silver nanoparticle on general performance and digestive proteases in zebra fish. four experimental diets were designed with a concentration of 5, 20 and 40 parts per billion (ppb) nanoparticles in the diet (named s5, s20, and s40, respectively) and control group without any nanoparticles (s0). there was no significa...
Extracellular serine protease cascades have evolved in vertebrates and invertebrates to mediate rapid, local reactions to physiological or pathological cues. The serine protease cascade that triggers the Toll signaling pathway in Drosophila embryogenesis shares several organizational characteristics with those involved in mammalian complement and blood clotting. One of the hallmarks of such cas...
Proteases mediate important crucial functions in parasitic diseases, and their characterization contributes to the understanding of host-parasite interaction. A serine protease was purified about 43-fold with a total recovery of 60% from a detergent-soluble extract of promastigotes of Leishmania amazonensis. The purification procedures included aprotinin-agarose affinity chromatography and gel ...
Changes in barrier function of the gastrointestinal tract are thought to contribute to the inflammatory bowel diseases Crohn's disease and ulcerative colitis. Previous work in our lab demonstrated that apical exposure of intestinal epithelial cell lines to serine proteases results in an increase in transepithelial electrical resistance (TER). However, the underlying mechanisms governing this re...
