Chemotaxis Induced by CXCL13/BLC/BCA‑1 and Neutralization by Human CXCL13/BLC/BCA‑1 Antibody.

Chemotaxis Induced by CXCL13/BLC/BCA‑1 and Neutralization by Human CXCL13/BLC/BCA‑1 Antibody.

Recombinant Human CXCL13/BLC/BCA-1 (Catalog # 801-CX) chemoattracts the BaF3 mouse pro-B cell line transfected with human CXCR5 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin. Chemotaxis elicited by Recombinant Human CXCL13/BLC/BCA-1 (50 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human CXCL13/BLC/BCA-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF801). The ND50 is typically 1-4 µg/mL.

CXCL13/BLC/BCA-1 antibody in Human Lymphoma by Immunohistochemistry (IHC-P).

CXCL13/BLC/BCA‑1 in Human Lymphoma.

CXCL13/BLC/BCA-1 was detected in immersion fixed paraffin-embedded sections of human lymphoma using Goat Anti-Human CXCL13/BLC/BCA-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF801) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.

Detection of CXCL13/BLC/BCA‑1 in Human Lymphoma.

Formalin-fixed paraffin-embedded tissue sections of Hodgkin’s Lymphoma were probed for CXCL13 mRNA (ACD RNAScope Probe, catalog # 311321; Fast Red chromogen, ACD catalog # 322360). Adjacent tissue section was processed for immunohistochemistry using goat anti-human CXCL13 polyclonal antibody (R&D Systems catalog # AF801) at 5ug/mL with 1-hour incubation at room temperature followed by incubation with anti-goat IgG VisUCyte HRP Polymer Antibody (Catalog # VC004) and DAB chromogen (yellow-brown). Tissue was counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.

The anti-tumor function of Tfh cells was impaired in PDAC. (A) Representative flow cytometry data and the proportion of functional cTfh cells (CXCL13+ IL-21+) from the peripheral blood of healthy donors (n = 4) and patients with PDAC of different stages (nI = 5, nII = 4, nIII = 4). (B) Representative flow cytometry data and (C) the proportion of CD8+ T cells and B cells recruited to the bottom of the Transwell chamber by cTfh cells treated with or without rhCXCL13 or anti-CXCL13 neutralizing antibodies. (D) Representative flow cytometry data and the proportion of plasma cells (CD27+ CD38+) in B cells (CD19+ CD20+) from the peripheral blood of healthy donors (n = 4) and patients with PDAC at different stages (nI = 5, nII = 4, nIII = 4). (E) Representative flow cytometry data and the proportion of IgG-secreting plasma cells from cells in (D). (F) Representative flow cytometry data and the proportion of IgM-secreting plasma cells from cells in (D). (G) Representative flow cytometry data and the proportion of plasma cells (CD27+ CD38+) in B cells (CD19+ CD20+) co-cultured with cTfh cells sorted from the peripheral blood of healthy donors (n = 3) and patients with PDAC (n = 3). (H) Representative flow cytometry data and the proportion of IgG-secreting plasma cells from cells in (G). (I) Representative flow cytometry data and the proportion of IgM-secreting plasma cells from cells in (G). Asterisks indicated the significance level of the p-value (* p < 0.05 and ** p < 0.01).

Background: CXCL13/BLC/BCA-1

CXCL13, also known as B-lymphocyte chemoattractant (BLC), is a CXC chemokine that is constitutively expressed in secondary lymphoid organs. BCA-1 cDNA encodes a protein of 109 amino acid residues with a leader sequence of 22 residues. Mature human BCA-1 shares 64% amino acid sequence similarity with the mouse protein and 23‑34% amino acid sequence identity with other known CXC chemokines. Recombinant or chemically synthesized BCA-1 is a potent chemoattractant for B lymphocytes but not T lymphocytes, monocytes or neutrophils. BLR1, a G protein-coupled receptor originally isolated from Burkitt’s lymphoma cells, has now been shown to be the specific receptor for BCA1. Among cells of the hematopoietic lineages, the expression of BLR1, now designated CXCR5, is restricted to B lymphocytes and a subpopulation of T helper memory cells. Mice lacking BLR1 have been shown to lack inguinal lymph nodes. These mice were also found to have impaired development of Peyer’s patches and defective formation of primary follicles and germinal centers in the spleen as a result of the inability of B lymphocytes to migrate into B cell areas.
