Chemokine redundancy versus specificity in the context of CXCR3 and its ligands.

In a recent article published in Immunology & Cell Biology, Dalit et al. describe how correcting mutations in the C57BL/6 mouse strain can restore production of the chemokine CXCL11, although surprisingly, this expression of CXCL11 had little effect on B and T cells and the innate immune response to infection with lymphocytic choriomeningitis virus or influenza virus.
