cytotoxic t lymphocyte associated molecule -4 (ctla-4) gene polymorphisms in ovarian cancer patients
background: ovarian cancer is a relatively common cancer among postmenopausal women. nowadays, there is controversy about immunotherapy of ovarian cancer patients with interleukins such as interferon to reach better out come in prognosis of patients under chemotherapy. ctla-4 is a gene, which has an important role in homeostasis and regulation of immune response. inhibitory nature of ctla-4 is ...
متن کاملInduction of Cytotoxic T Lymphocyte Antigen 4 (Ctla-4) Restricts Clonal Expansion of Helper T Cells
Cytotoxic T lymphocyte antigen (CTLA)-4 plays an essential role in immunologic homeostasis. How this negative regulator of T cell activation executes its functions has remained controversial. We now provide evidence that CTLA-4 mediates a cell-intrinsic counterbalance to restrict the clonal expansion of proliferating CD4(+) T cells. The regulation of CTLA-4 expression and function ensures that,...
متن کاملRigid-body Ligand Recognition Drives Cytotoxic T-lymphocyte Antigen 4 (CTLA-4) Receptor Triggering
The inhibitory T-cell surface-expressed receptor, cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), which belongs to the class of cell surface proteins phosphorylated by extrinsic tyrosine kinases that also includes antigen receptors, binds the related ligands, B7-1 and B7-2, expressed on antigen-presenting cells. Conformational changes are commonly invoked to explain ligand-induced "trigge...
متن کاملCytotoxic T Lymphocyte–associated Antigen 4 (CTLA-4) Regulates the Unfolding of Autoimmune Diabetes
Evidence has been accumulating that shows that insulin-dependent diabetes is subject to immunoregulation. To determine whether cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is involved, we injected anti-CTLA-4 mAb into a TCR transgenic model of diabetes at different stages of disease. When injected into young mice, months before they would normally become diabetic, anti-CTLA-4 induced di...
متن کاملCytotoxic T lymphocyte antigen-4 (CTLA-4) A49G polymorphism and autoimmune blood diseases.
OBJECTIVE The cytotoxic T lymphocyte associated antigen-4 (CTLA-4) is expressed on T lymphocytes, and inhibits the T-cell responses. In animal models, it has been shown that complete CTLA-4 deficiency was lethal due to massive infiltration of tissues by polyclonally proliferating lymphocytes. CTLA-4 A49G polymorphism, which has been suggested to reduce the inhibitory function of the CTLA-4 mole...
