Description

Description: This 87.1 monoclonal antibody reacts with non-human primate (specifically rhesus) CD185. CD185, which is also known as C-X-C chemokine receptor 5 (CXCR5) and Burkitt lymphoma receptor 1 (BLR1), is a seven transmembrane G protein-coupled receptor originally identified in Burkitt's lymphoma. In peripheral blood, CD185 is expressed on B cells, CD4+ T cells (but not Th1 or Th2 cells), and a subpopulation of memory (CD45RO+) T cells. CD185+ circulating T cells are in a resting state and migrate to the lymph nodes due to CCR7 and CD62L expression. In tonsils, CD185 is expressed on nearly all CD4+ cells along with CD45RO and the activation markers CD69 and ICOS. Tonsillar CD185+ cells have been shown to induce antibody production when co-cultured with B cells, thus supporting their role in providing B cell help. Furthermore, this chemokine receptor plays a critical role in lymphocyte trafficking, in particular CXCL13-induced T cell migration into the B cell follicles of germinal centers. Thus, CD185 is an established marker of follicular helper T cells (Tfh). In rhesus macaques, infection with simian immunodeficiency virus (SIV) has been reported to increase the number of germinal centers and Tfh cells within the lymph nodes. Refer to the rhesus reactive alternative clone MU5UBEE (cat. 12-9185) for identification of CXCR5 on T cells in addition to B cells. Applications Reported: This 87.1 antibody has been reported for use in flow cytometric analysis.

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.
