Comment: CXCL13 is a C-X-C motif homeostatic chemokine that is selectively chemotactic for B cells belonging to both the B-1 and B-2 subsets. It exerts its biological effects via binding to the chemokine receptor CXCR5. CXCL13 expression can be regulated by the lymphotoxin β receptor (LTBR) pathway, and it contributes to ectopic tertiary lymphoid tissue development at sites of chronic inflammation in several autoimmune diseases, for example in the lacrimal and salivary glands of Sjögren's patients [4]. The CXCL13/LTBR axis is considered as a potential therapeutic target in conditions like Sjögren's syndrome. This is evidenced by the development of pharmaceutical agents that block LTBR activity being advanced to clinical trials (e.g. baminercept (BG9924) which is a soluble LTBR-IgG Fc fusion protein [3]).
