Regulatory effect of Vav1 on T cells and its relation to clinical diseases
2018
: Vav1, as a key downstream signaling molecule of T cell receptor, includes a catalytic core DH-PH-ZF domain with the function as guanine nucleotide exchange factor (GEF), and a SH3-SH2-SH3 domain with the function as adaptor protein. These two structures of Vav1 play different roles in the development, activation, proliferation and function of T cells, and thereby exert the different regulatory effect on the occurrence and development of autoimmune disease, graft rejection, cancer and other clinical conditions, implicating that Vav1 might be a potential therapeutic target for these diseases. This paper reviews the role of Vav1 in T cells and the occurrence of related diseases.
