Cytokine regulation of B-cell migratory behavior favors formation of germinal centers in autoimmune disease.

ABSTRACT: Chemotaxis is essential for shaping immune responses and chemokine-receptor antagonists are now being evaluated as therapies for various inflammatory and autoimmune diseases. However, the dysregulation of chemotaxis in autoimmune disease may involve both promotion and inhibition of B-cell migration. This review focuses on the disparate mechanisms by which two inflammatory cytokines that have been associated with autoimmune disease, namely interferon-alpha (IFN-alpha) and interleukin-17 (IL-17), may regulate B-cell migratory responses. Chemotactic responses play a key role in orchestrating the cell-cell interactions in the germinal centers (GCs). This process involves active shuttling of the antigen-carrying B cells between the marginal zone and the GCs. We have shown that in autoimmune BXD
