IL-2-dependent activated cells undergo apoptotic death when IL-2 is withdrawn either in vitro or after in vivo cell transfer. To attempt to sustain their survival after IL-2 withdrawal, melanoma-reactive human T lymphocytes were retrovirally transduced with an exogenous human IL-2 gene. Transduced PBMC and cloned CD8+ T cells produced IL-2 and maintained viability after IL-2 withdrawal. Upon re...

Introduction: Muscular inflammation and atrophy is one of the characteristics of diabetes that causes motor disability in these individuals. Studies have shown that exercise training with different intensities and the use of herbal drugs can have favorable effects on diabetes. The aim of this study was to interactive effects of continuous and interval training with crocin consu...

Interleukin 2 (IL-2) is an important lymphokine required in the process of T cell activation, proliferation, clonal expansion and differentiation. The IL-2 gene displays both T cell specilic ahd inducible expression: it is only expressed in CD4+ T cells after antigenic or mitogenic stimulation. Several cis-acting regulatory sites are required for induction of the IL-2 gene after stimulation. In...

Objective(s): Systemic lupus erythematosus (SLE) is a multi-factorial autoimmune disease which may be characterized by T lymphocytes dysfunctions. Th17 cells have been identified as new effector cells, which play an important role in the pathogenesis. In recent years, immunomodulatory effect of vitamin D3 has been noticed. In the present experiment, the effect of vitamin D3 on the expression of...

background: interleukin (il)-23 and il-27 are two il-12-related cytokines which their function may dramatically influence the inflammatory response to tumor development. il-12 and il-27 seem to have antagonistic roles with il-23 in tumor site. in this study, il-23 and il-27 mrna expressions were analyzed in peripheral blood of patients with breast cancer and healthy volunteers using quantitativ...

BACKGROUND The biological effects of cytokines are coming to be understood. The therapeutic effects of interleukin (IL) 2, IL-12, and interferon gamma (IFN-gamma) in cancer treatment have been reported, but there are problems when these cytokines are systemically used as therapeutic agents. OBJECTIVE To examine the efficacy of IL-2 and IL-12 gene-transfected tumor cell vaccines for head and n...

conclusions some il-10 promoter gene polymorphisms predisposed the infected hepatitis b virus cases to cirrhosis in our study population. patients and methods totally, 166 patients with chronic hepatitis b infection were enrolled. genotypes at different positions (i.e. -819, - 592, and - 1082) in the il-10 gene promoter were determined. results the c/a genotype at position -592, c/t genotype at...
