The Role of Soluble TNF Receptors for TNF- in Uveitis
نویسندگان
چکیده
METHODS. Ocular fluid samples were collected from patients with active and inactive uveitis, as well as from control subjects without uveitis. The sTNF-Rs and TNFlevels were measured by enzyme-linked immunosorbent assay (ELISA). T-cell clones (TCCs) were established from intraocular infiltrating cells, and the TCCs were cocultured with recombinant sTNF-Rs or TNF. The supernatants were measured by ELISA. The neutralization of sTNF-R production by TCCs was evaluated with an anti-human TNF-R antibody.

Tumor necrosis factor-alpha (TNF-α) is a pro-inflammatory cytokine produced by a variety of cells, including hematopoietic and non-hematopoietic cells, malignant cells, macrophages, B lymphocytes, T lymphocytes, natural killer cells, neutrophils, astrocytes, endothelial cells, and smooth muscle cells. TNF-α is a homo-trimeric molecular whose individual subunits are composed of antiparallel beta...

Background & Objective: Systemic lupus erythematosus (SLE) is a disease with life-threatening complications. Since evidence indicates that measurement of triglyceride (TG) and HDL levels and tumor necrosis α factor (TNF- α) and its types I and II soluble receptors plays a major role in evaluation of lupus activity, this study was conducted to investigate the relationship between the above menti...

Background: Tumor necrosis factor alpha (TNF-) is a major mediator of inflammatory responses and also plays a role in Febrile non-hemolytic reactions (FNHRs) after platelet concentrates (PCs) injection. It is thought contaminating WBCs are the source of these cytokine so inactivating or decreasing of these WBCs will be effective to decline of the cytokines. Due to difference results between di...

Background : We investigated the mechanism of action of Dendrostellera lessertii effects on decreasing size of adeno-carcinoma of rat intestine and breast tumors. This purpose followed by assessing its effects on TNF-α and TNF-α receptors on cultured human monocytes. Material and method : The breast and intestine tumors were induced in rats by DMBA and DMH, respectively. Human monocytes isolat...
