the aim of this study was to investigate the possible influence of interferon-gamma (ifn- γ) gene polymorphism +874 (a/t) (rs2430561) in the susceptibility and renal complications of patients with henoch-schonlein purpura (hsp). we also studied the effects of ifn-γ allelic variation on serum levels of pro-and anti-inflammatory cytokines in hsp patients. the  study  population  comprised  97  pa...

background: the aim of this study was to determine the th1 and th2 serum cytokines, in patients with psoriasis and to com pare their cytokine levels with those of normal control subjects. methods: serum levels of interferon-gamma (ifn-γ), interleukin-2 (il-2), interleukin-4 (il-4), and interleukin-10 (il-10) were measured by enzyme linked immunosorbent assay in 40 patients with psoriasis and in...

background : cytokines produced by different subsets of t cells are the key mediators to adjust the quality of immune responses. despite evidence of induction of an immune reaction against tumors such as breast cancer, not all responses are protective. in this study we attempt to evaluate the expression profile of several cytokines from the t helper 1 and 2 subsets in blood cells from patients ...
