Cytotoxic 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 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-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 کاملDrug-associated dermatomyositis following ipilimumab therapy: a novel immune-mediated adverse event associated with cytotoxic T-lymphocyte antigen 4 blockade.
IMPORTANCE Ipilimumab, a human monoclonal antibody targeted against cytotoxic T-lymphocyte antigen 4, has shown promise in the treatment of metastatic melanoma. However, given its mechanism of action, immune-related adverse effects have been reported with this therapy. Despite increasing reports of immune-related adverse effects related to ipilimumab therapy, dermatomyositis associated with thi...
متن کاملEnterocolitis in patients with cancer after antibody blockade of cytotoxic T-lymphocyte-associated antigen 4.
PURPOSE Cytotoxic T-lymphocyte-associated antigen 4 (CTLA4) is an inhibitory receptor on T cells. Knocking out CTLA4 in mice causes lethal lymphoproliferation, and polymorphisms in human CTLA4 are associated with autoimmune disease. Trials of the anti-CTLA4 antibody ipilimumab (MDX-010) have resulted in durable cancer regression and immune-mediated toxicities. A report on the diagnosis, patholo...
