 B  Cell-Attracting Chemokine 1 (BCA1) 
  CXCL13 is a CXC chemokine lacking the ELR motif. It is expressed highest in liver tissue, followed by spleen, lymph nodes, appendix, and stomach. It is a ligand for CXCR5 and is selectively chemotactic for B lymphocytes. CXCL13 plays an essential role in the development of lymph nodes and the organization of B cells within lymphoid follicles, but its expression is downregulated within lymphoid tissues by IFN-gamma during immune responses. CXCL13 induces B cells to upregulate lymphotoxin alpha-1-beta-2, leading to CXCL13 expression and creating a positive feedback loop essential for follicular dendritic cell development and homeostasis.
