Diffuse large B cell lymphoma (DLBCL) is the most frequent lymphoma accounting for more than the 30% of the cases. Involvement of extranodal sites, such as bone marrow and central nervous system, is associated with poor prognosis. A contribution of the chemokine system in these processes is assumed as it is known as a critical regulator of the metastatic process in cancer. The atypical...

CXCR7 prevents excessive CXCL12-mediated downregulation of CXCR4 in migrating cortical interneurons

Abe, Philipp ; Mueller, Wiebke ; Schütz, Dagmar ; MacKay, Fabienne ; Thelen, Marcus ; Zhang, Penglie ; Stumm, Ralf

The CXCL12/CXCR4 signaling pathway is involved in the development of numerous neuronal and non-neuronal structures. Recent work established that the atypical second CXCL12 receptor, CXCR7, is essential for the proper migration of interneuron precursors in the developing cerebral cortex. Two CXCR7-mediated functions were proposed in this process: direct modulation of β-arrestin-mediated...

Expression of CXCL12 receptors in B cells from Mexican Mestizos patients with systemic lupus erythematosus

Biajoux, Vincent ; Bignon, Alexandre ; Freitas, Christelle ; Martinez, Valérie ; Thelen, Marcus ; Lima, Guadalupe ; Jakez-Ocampo, Juan ; Emilie, Dominique ; Llorente, Luis ; Balabanian, Karl

Background: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by B-cell hyperreactivity and the production of pathogenic anti-nuclear- directed auto-antibodies (Abs). B-cell ontogeny is partly dependent on the CXCL12/CXCR4 axis for which the contribution to SLE pathogenesis remains unclear. CXCR7, the novel receptor for CXCL12, is differentially expressed among...
