background:the premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. so, it is necessary to tightly control ifn-γ pr...

Objective(s) Previous studies have demonstrated that the nitric oxide (NO) dependent death of murine peritoneal macrophages activated in vitro with IFN-g and LPS is mediated through apoptosis. In the present study, we investigated the synergistic effect of LPS, IFN-g and iron on NO production and apoptosis. Materials and Methods After determination of iron cytotoxicity, the peritoneal macrop...

Background: IBD is a chronic inflammatory condition associated with damage to the intestinal mucosal barrier. Supplementation of yacon tubers has been known to give positive effect in intestinal health. Therefore, we conducted the study to investigate the effect of yacon tuber powder on Th1 activation pathway by evaluating IFN-γ levels and the number of goblet cells in the colon of colitis mous...
