A previous study showed that increases in chemokine expression and recruitment of antibody secreting cells (ASCs) in the CNS after intracerebral immunization contributed to the suppression of a neurotropic virus. In this study, intracerebral chemokine injection was used to investigate the usefulness of chemokines for controlling neurotropic viruses. Both CXCL12 and a cocktail chemokine (a mixture of CXCL9, 10, 12 and 13) attracted antigen-specific ASCs more strongly than CXCL9, 10 and 13 in an in vitro chemotaxis assay and in vivo intracerebral chemokine injection experiments. Mice pre-treated intracerebrally with CXCL12 and the cocktail chemokine showed an increased survival rate after intracerebral infection with rabies virus. These results suggest that intracerebral CXCL12 injection induces the migration of ASCs and suppresses the neuropathogenicity of rabies virus in the CNS. Copyright © 2012 Elsevier B.V.
