WebCytotoxic T-lymphocyte antigen 4 (CTLA-4) is an immune checkpoint receptor that negatively regulates the immune response. Blocking CTLA-4 may directly restore T-cell activation, reverse regulatory T cell (Treg) - driven T-cell suppression, and lead to long-term antitumor immunity. Research is ongoing to further optimize CTLA-4 blockade. Variants in this gene have been associated with Type 1 diabetes, Graves' disease, Hashimoto's thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, primary biliary cirrhosis and other autoimmune diseases. Polymorphisms of the CTLA-4 gene are associated with autoimmune diseases such as rheumatoid arthritis, autoimmune thyroid disease and multiple sclerosis, though this associatio…
WebJan 15, 2024 · CTLA-4, an immunoglobulin cell surface receptor, is an inhibitor of T cell activation [ 5, 6 ]. It is primarily expressed on naïve T cells after activation [ 7] and FoxP3 + regulatory T cells (Tregs) [ 8 ]. WebJan 17, 2024 · After CTLA-4 inhibition, massive immune cell infiltration accompanied tumor regression (Figure 1E), with a dramatic increase in T and B/plasma cell proportions (Figure 1F). Flow cytometry analysis confirmed the expansion of T and B cell populations after the CTLA4 inhibition, with variations in individual mice (Figures 1G and S1C,D).
WebMay 1, 2024 · In this phase II trial, we found that the PD-L1 inhibitor, durvalumab, and CTLA-4 inhibitor, tremelimumab, combined with either HFRT or LDFRT directed against 1–2 liver metastases was tolerated, with the spectrum and frequency of immune-related adverse events expected from combined PD-1/L1 and CTLA-4 blockade alone . No … WebAlthough the mechanism by which CTLA-4 enhances the inhibitory function of Tregs is not known, Treg-specific CTLA-4 knockout or blockade significantly inhibits their ability to regulate both autoimmunity and antitumor immunity. 248,249 Thus, in considering the mechanism of action for CTLA-4 blockade, both enhancement of effector CD4 T-cell …
