Effects of cystatins derived from two species of helminths on the release of nitric oxide and secretion of cytokines from murine peritoneal exudate cells
Objective To investigate the effects of cysteine protease inhibitors(cystatins) from Trichinella spiralis(Tscystatin) and Angiostrongylus cantonensis(Accystatin) on the release of nitric oxide(NO) and secretion of cytokines from mouse peritoneal exudate cells(PECs). Methods Ten BALB/c mice were sacrificed under anesthesia to collect intraperitoneal fluid, from which PECs were prepared, consisting mostly of macrophages. The lipopolysaccharide(LPS)-stimulated PECs were incubated with Tscystatin or Accystatin....
