Cytotoxic T-lymphocyte-associated antigen-4.
Cancer immunotherapy relies on the ability of the immune system to target tumor-specific antigens to generate an immune response. This initial response requires both binding of the MHC/antigen peptide to T-cell receptor complex, along with a second costimulatory signal created by the binding of CD28 on the T cell, with B7 located on the antigen-presenting cell. Regulatory checkpoints, such as c...
متن کاملCytotoxic T-lymphocyte Associated Antigen-4 (CTLA-4) Polymorphism, Cancer, and Autoimmune Diseases
Immune system dysfunction is one of the key features in onset and development of cancer and autoimmunity. Cytotoxic T-lymphocyte-antigen-4 (CTLA-4), as a leader immune checkpoint plays a crucial effects in the regulation of immune suppression and tolerance. In this review, role of CTLA-4 and its three important polymorphisms (SNP), CTLA-4 +49A/G, CTLA-4 CT60 A/G and CTLA-4 −318C/T in developmen...
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 کاملB and T Lymphocyte Attenuator is a Target of miR-155 during Naive CD4+ T Cell Activation
Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...
