introduction and aims: impact of treatment on progression of fibrosis in autoimmune hepatitis (aih) is unknown. we assessed the changes in liver fibrosis before and after treatment among these patients. materials and methods: nineteen aih patients who had paired liver biopsies were studied. of these, seven had been treated with 6 months of cyclosporine-a and the rest with 6 months of prednisolo...

silybum marianum, is known to have anti-inflammatory, hepatoprotective and anticarciogenic effects. the aim of this study was to compare effects of silymarin, rapamycin and fk506 on proliferation and apoptosis of human t cells stimulated with con a. peripheral blood mononuclear cells (pbmc) were stimulated with concavalin a  ( con a) (5µg/ml) and then treated with different inhibitors (silymari...

background: the expanse of dendritic cells (dc) differentiation plays an important role in determining immune response. dc-based immunosuppressive drugs have notable side effects in increasing the risk of infectious diseases and cancers. g2013, as a novel anti-inflammatory and immunosuppressive agent, has been tested in experimental model of multiple sclerosis. the aim of this study was to cond...

Immunoglobulin G-binding factors (IgG-BF), which are produced by cells of the immune system, inhibit antibody production . In this paper, we show that transforming growth factor-(3 (TGF-(3) suppresses secondary in vitro anti-sheep red blood cell responses of mouse splenocytes and lipopolysaccharideor anti-IgM--stimulated mouse B cell responses in a way similar to, and with the same kinetics as,...

Immunotherapy has been used for years in many types of cancer therapy. Recently, cancer immunotherapy has focused on mechanisms which can enhance the development of cell-mediated immunity. Anticancer medications are administered to inhibit immunosuppressive factors such as nagalase enzyme, which is produced by neoplastic cells and destroys macrophage activating factor (Gc-MAF). Anti-neoplastics...

background: the pathogenesis of many diseases is correlated to irregularity in vascular endothelial growth factor (vegf) expression. results from several association studies show that variation in the level of vegf expression is related to polymorphic sequences within the vegf gene. additionally, there are many studies showing that some gene polymorphisms significantly influence the pharmacokin...
