Biochem/physiol Actions

BCA-1 is a potent chemoattractant for B lymphocytes, but not T lymphocytes, monocytes, or neutrophils.
BCA-1 is a potent chemoattractant for B lymphocytes, but not T lymphocytes, monocytes, or neutrophils. Its specific receptor BLR1 is a G protein-coupled receptor originally isolated from Burkitt′s lymphoma cells. Among cells of the hematopoietic lineages, the expression of BRL1, now designated CXCR5, is restricted to B lymphocytes and a subpopulation of T helper memory cells.
The biological activity of human BLC/BCA-1 is measured by its ability to chemoattract mouse BaF/3 cells transfected with human CXCR5.

Physical form

Lyophilized from a 0.2 μm filtered solution in 35% acetonitrile and 0.1% TFA containing 50 μg bovine serum albumin per 1 μg of cytokine.

Abnormal overexpression of CXCL13 is observed in many inflamed tissues and in particular in autoimmune diseases. Myasthenia gravis (MG) is a neuromuscular disease mainly mediated by anti-acetylcholine receptor autoantibodies. Thymic hyperplasia characterized by ectopic germinal centers (GCs) is a common

Although most leukocytes, T lymphocytes in particular, respond to several different chemokines, there is virtually no information on chemokine activities and chemokine receptors in B lymphocytes. A putative chemokine receptor, BLR1, that is expressed in Burkitt's lymphoma cells and B

We describe the phenotype of gene-targeted mice lacking the putative chemokine receptor BLR1. In normal mice, this receptor is expressed on mature B cells and a subpopulation of T helper cells. Blr1 mutant mice lack inguinal lymph nodes and possess

Secondary lymphoid organs (spleen, lymph nodes and Peyer's patches) are divided into compartments, such as B-cell zones (follicles) and T-cell zones, which provide specialized environments for specific steps of the immune response. Migration of lymphocyte subsets into these compartments is

To investigate the effect of CXCL13 (C-X-C motif chemokine 13) on hepatocellular carcinoma and clarify the potential mechanisms. 32 patients with hepatocellular carcinoma and 12 healthy controls were recruited for analyzing the expression of CXCL13 by RT-PCR (reverse transcription-polymerase chain
