Target Information
CD185, also known as CXCR5 or Burkitt lymphoma receptor 1 (BLR1), is a seven-transmembrane G protein-coupled receptor in the CXC chemokine receptor family. It plays a crucial role in lymphocyte trafficking, particularly in T cell migration into B cell follicles of germinal centers in response to CXCL13, making it a key marker of follicular helper T cells. In peripheral blood, CXCR5 is expressed on B cells, CD4+ T cells (excluding Th1 and Th2 cells), and a subset of memory (CD45RO+) T cells. These CD185+ T cells are in a resting state and migrate to lymph nodes due to CCR7 and CD62L expression. In tonsils, CD185 is found on nearly all CD4+ cells, along with activation markers like CD69 and ICOS, and can induce antibody production when co-cultured with B cells. CXCR5 is expressed in lymphatic tissues such as lymph node follicles and the spleen, and is also found in human blood and salivary glands, as well as various animal tissues. It is essential for B cell migration and is part of the larger family of G protein-coupled receptors (GPCRs), which have seven membrane-spanning helices and are involved in numerous signaling pathways. GPCRs, including CXCR5, are regulated by various ligands that affect their conformation and signaling through G-proteins and downstream effectors. The regulation of GPCRs, including their deactivation, has significant implications for cellular functions and is a major focus of pharmacological research, leading to the development of drugs like Zyprexa and Claritin for mental health and allergy treatments.
