recent studies have established that sex hormones directly or indirectly affect t and b cells and macrophages by manipulating the production of cytokines. in this study the possibility of the effect of 5a-dht on macrophage (mφ) nitric oxide (no) release via interleukin-l, 6 (ll-1β, il-6) or tumor necrosis factor-a (tnfα) was investigated. the endogenous cytokines il-1β, il-6 and tnf-α were neut...

background: the expression of mouse tumor necrosis factor alpha (tnf-α) in escherichia coli is a favorable way to get high yield of protein; however, the formation of cytoplasmic inclusion bodies, which is the consequence of insoluble accumulated proteins, is a major obstacle in this system. to overcome this obstacle, we used a pulsed dilution method to convert the product to its native conform...

the aim of this study was to examine the anti-inflammatory effects of co-administration of growthhormone-releasing peptide-2 (ghrp-2) and growth hormone (gh) on tumor necrosis factor-α (tnf-α),interleukin-6 (il-6) and inducible nitric oxide synthase (inos) gene expression induced by lps in the mousebrain. thirty-five male nmri mice (25±5 g) were injected through the mouse tail vein with saline,...

The aim of this study was to examine the anti-inflammatory effects of co-administration of growthhormone-releasing peptide-2 (GHRP-2) and growth hormone (GH) on tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and inducible nitric oxide synthase (iNOS) gene expression induced by LPS in the mousebrain. Thirty-five male NMRI mice (25±5 g) were injected through the mouse tail vein with saline,...

Background and Aims: Plants as medicines have always played a vital role in human life. Tumor necrosis factor alpha (TNF)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. Some studies have been demonstrated that some of the Echinops species have anti-inflammatory activity. In fact, Echinops lasilepis is introduced as one of the ...

125I-labeled TNF(LuKII) (tumor necrosis factor) binds specifically to human and mouse cell lines sensitive to the cytotoxic effect of TNF, but not to cells made resistant to TNF. TNF-sensitive cells have cell surface receptors with a high affinity for TNF(LuKII). Mouse TNF competes with TNF(LuKII) for receptor binding. Scatchard analysis of the binding data yielded linear plots and suggests tha...
