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 کاملAnti-cytotoxic T lymphocyte antigen-4 antibodies in melanoma
Approaches aimed at enhancement of the tumor specific response have provided proof for the rationale of immunotherapy in cancer, both in animal models and in humans. Ipilimumab, an anti-cytotoxic T lymphocyte antigen-4 (CTLA-4) antibody, is a new generation immunotherapeutic agent that has shown activity in terms of disease free and overall survival in metastatic melanoma patients. Its use was ...
متن کاملCytotoxic T lymphocyte antigen-4 and immune checkpoint blockade.
The relationship between cancer and the immune system is complex and provides unique therapeutic opportunities. Cytotoxic T lymphocyte antigen-4 (CTLA-4) is a regulatory molecule that suppresses T cell effector function following initial activation by costimulatory signals. Fully human monoclonal antibodies targeting CTLA-4 have been shown to increase T cell function and antitumor responses in ...
متن کاملCytotoxic T lymphocyte antigen - 4 and immune checkpoint blockade
Introduction The immune system is an important defense against the development and progression of cancer (1). Historically, there has been a waxing and waning enthusiasm for immune therapies to treat cancer due to limited efficacy. Immunotherapies, such as IL-2 and adoptive transfer of autologous tumor-infiltrating lymphocytes, can induce durable tumor responses in a subset of patients, leading...
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,...
