C-X-C motif chemokine 13 (CXCL13) also known as B lymphocyte chemoattractant (BLC) is a protein that in humans is encoded by the CXCL13 gene.[1][2]
Function
CXCL13 is a small cytokine belonging to the CXC chemokine family. As its name suggests, this chemokine is selectively chemotactic for B cells belonging to both the B-1 and B-2 subsets, and elicits its effects by interacting with chemokine receptor CXCR5.[1][3] CXCL13 and its receptor CXCR5 control the organization of B cells within follicles of lymphoid tissues.[4] and is expressed highly in the liver, spleen, lymph nodes, and gut of humans.[1] The gene for CXCL13 is located on human chromosome 4 in a cluster of other CXC chemokines.[2]
In T-lymphocytes, CXCL13 expression is thought to reflect a germinal center origin of the T-cell. Hence, expression of CXCL13 in T-cell lymphomas, such as Angioimmunoblastic T-cell Lymphoma, is thought to reflect a germinal center origin of the neoplastic T-cells.[5]
