Based on these observations, we next focused on defining the events that regulate the development of CXCL13 + MRC-like cells within the IFR of the mLN following infection. For instance, T cells … As its other names suggest, 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 CXCR5. CCL19/CCL21–CCR7 play an analogous role for T-cell–dendritic cell positioning in T-cell zones. Thus, CXCL13 production by interfollicular MRC-like cells is likely to play an important role in the T cell-DC interactions that are known to be important in driving T helper 2 responses.

In fact, thymic T cells express CCR9, and it is assumed that the CCL25/CCR9 axis is important for T cell development in particular on late double-negative and double-positive maturing cells. Name. CXCL13 and its receptor CXCR5 are essential for trafficking B cells and homing B cells to lymphoid tissues and for the embryonic development of the majority of lymph nodes and Peyer's patches (Ansel et al., 2000). Further study is required to clarify any potential role of neuronal stimulation in BALT development or function. The chemokine CXCL13 mediates recruitment of B cells to tumors and is essential for the formation of tertiary lymphoid structures (TLSs). Objective. CXCR5 is the receptor for the chemokine CXCL13, the chemokine important for secondary lymphoid tissue orchestration and lymphoid neogenesis. In the Myc-CaP and TRAMP prostate cancer models in vivo, CXCL13 is upregulated by myofibroblasts in the tumor stroma downstream of TGF-β in response to hypoxia, and this promotes metastasis and the development of more aggressive, hormone-independent tumors (Ammirante, Shalapour, Kang, Jamieson, & Karin, 2014). CD10 and CXCL13 have been recently recognized as characteristic markers of AITL, but have not been yet investigated in the skin. Mice deficient in either CXCL13 or its receptor, CXCR5, lack structured lymphoid organs including lymph nodes, Peyer's patches, and spleen, which appears due to a lack of follicular DC networks that are required for the organization of recruited B cells into follicles/germinal centers (Ansel et al., 2000). It may therefore function in the homing of B lymphocytes to follicles. It also remains to be seen whether this mutation is specific for AITL or other subtypes of PTCL derived from TFH cells. In the ectopic lymphoid‐like structures present in chronic inflammatory conditions such as rheumatoid arthritis, a subset of human effector memory CD4 + T cells that lacks features of follicular helper T (Tfh) cells produces CXCL13. By contrast, CXCR4 is not required for T cell lymphopoiesis. In homeostasis, CXCL13 is produced by high endothelial venules and by the follicular dendritic cells in B cell follicles. Results: CD4 T-cells of rheumatoid synovitis produced CXCL13 ex vivo without exogenous stimulation of TCR or cytokines and flow cytometric analyses showed that the CXCL13+ CD4 T-cells were a population independent of IFN-γ + Th1, IL-4 + Th2, and IL-17 + Th17 cells. Kim et al. Other molecules such as PSGL1, sphingosine-1-phosphate receptor 1 (S1PR1), and EBI2 also regulate the migration of activated CD4+ T cells toward and into follicles (all molecules need to be downregulated). Instead, expression may coordinately mediate immune cell recruitment into the TME as well as promote the metastasis of tumor cells, as many forms of tumor/tumor cell lines have been shown to express chemokines or chemokine receptors. CXCR5 is expressed on blood and follicular B cells but becomes downregulated on plasmablasts and plasma cells (Shaffer et al., 2002; Humpert et al., 2014; Wehrli et al., 2001).
