CXCL13
chemokine (C-X-C motif) ligand 13 (CXCL13), also known as B lymphocyte chemoattractant (BLC) or B cell-attracting chemokine 1 (BCA-1), is a protein ligand that in humans is encoded by the "CXCL13" gene.
Function.
CXCL13 is a small chemokine 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
.
Rare primary FDC-tumors have been described. These sarcomas often involve lymphoid tissues, but in a number of cases the tumor has been found in the liver, bile duct, pancreas, thyroid, nasopharynx, palatum, submucosa of the stomach or the duodenum. 
In a number of chronic inflammatory conditions, cells producing CXCL13 chemokine and carrying such FDCs markers as VCAM-1 and CD21, have been observed at quite unexpected sites, including synovial tissue of patients with rheumatoid arthritis (RA), salivary glands of patients with
