Background and Objective: Oxidative stress induced by proinflammatory cytokines such as IL-1β plays a major role in β-cell destruction in diabetes type 1. Salvianolic acid B (Sal B) is a polyphenolic compound with antioxidant and protective effects. Thus, objective of this study was to assess the protection exerted by Sal B on isolated rat islets exposed to IL-1β and to investigate an underlyin...

background & objective: interleukin (il)-10 is an important anti-inflammatory and immunomodulatory cytokine. some authors believe that single nucleotide polymorphisms (snp) in the promoter region of the il-10 gene have been associated with susceptibility to hiv infection and progression to aids, but its role is not clearly defined yet. the present study was undertaken to evaluate the associ...

Interleukin (IL)-4 and IL-13 are related cytokines that share a common signaling pathway key drivers of several responses in atopic inflammation. Dendritic cells (DCs) potent antigen-presenting crucial for the situ activation polarization T to induce appropriate primary immune responses. Under specific conditions DCs can produce IL-12 IL-23 promote Th1 Th17 cell activity, respectively, thus ind...

AIM OF THE STUDY Aim of the study was to investigate interleukin (IL)-4 serum levels in patients with advanced endometriosis and whether IL-4 promoter region (-590C/T) genetic polymorphism is involved in genetic susceptibility to endometriosis. MATERIAL AND METHODS IL-4 serum levels and IL-4 -590C/T genetic polymorphism were determined for 80 patients with advanced endometriosis and 85 health...

BACKGROUND & OBJECTIVES Cytokine gene polymorphisms may alter Th1/Th2 balance with major implications in tuberculosis. The aim of our study was to find out whether Interferon gamma +874A and IL-4 -590T polymorphisms were associated with susceptibility to pulmonary tuberculosis as well as the level of IFNgamma and IL-4 in south Indian population. METHODS Interferon gamma +874A and IL-4 -590T p...

The effect of Sargassum pallidum (brown seaweed) aqueous extract on the immunity function and antioxidant activities in was studied gastric cancer rats. Treatment with Sargassum pallidum aqueous extract at oral doses 400, 600 or 800 mg/kg body weight was found to provide a dose-dependent protection against N-methyl-N′-nitro-Nnitrosoguanidine (MNNG)-induced immunity damage and oxidative injury b...

High in vitro lymphoproliferative responses were induced in humans and dogs by a recombinant Leishmania (Leishmania) chagasi cysteine proteinase, with secretion of IFN-gamma in asymptomatic subjects or of IFN-gamma, interleukin 4 (IL-4), and IL-10 in oligosymptomatic subjects. In contrast, responses of symptomatic patients and dogs were lower, with production of IL-4 and IL-10.
