Other Information

**Key characteristics:** - CTLA4 is a cell surface protein that is expressed on regulatory T cells. - It is a member of the immunoglobulin superfamily. - CTLA4 is responsible for blocking the activation of T cells by interacting with the CD28 protein on the surface of antigen-presenting cells. - CTLA4 is a key negative regulator of T cell responses. **Pathways and functions:** - CTLA4 is involved in the regulation of the adaptive immune response. - It is expressed in high levels on regulatory T cells, which are responsible for suppressing immune responses. - CTLA4 binds to CD28 on antigen-presenting cells, blocking the activation of the T cell and preventing the development of an immune response. - CTLA4 also inhibits the activation of other immune cells, such as dendritic cells and macrophages. - By blocking T cell activation, CTLA4 helps to maintain immune tolerance and prevent excessive immune responses. **Clinical significance:** - CTLA4 is a potential therapeutic target for autoimmune diseases, such as rheumatoid arthritis, psoriasis, and lupus. - Antibodies that block CTLA4 have shown promise in preclinical studies of these diseases, resulting in a reduction in inflammation and disease activity. - CTLA4 is a promising target for the development of novel immunotherapies for autoimmune diseases.
