What is Requirement of the IFN‐α/β‐induced CXCR3 chemokine signalling for CD8^+^ T cell activation about?

## Abstract **Background:** Activation of both CD4^+^ T and CD8^+^ T cells is triggered by the engagement of the T cell antigen receptor (TCR) with MHC/peptide complexes on antigen‐presenting cells. This process also requires other molecular interactions, which transmit co‐stimulatory signals to these T cells. To ensure an effective immune response, distinct T cell subsets may additionally employ unique mechanism(s) for efficient activation. **Results:** We here show that mutant CD8^+^ T cells lacking the IFN‐α/β signalling components are hyporesponsive to antigen stimulation __in vitro__. We further show that IFN‐α/β‐mediated signals are required for induction of the chemokines IP‐10/I‐TAC and their common receptor, CXCR3, and in turn provide evidence that CXCR3‐mediated signals indeed function in the activation and proliferation of CD8^+^ T cells, particularly for the CD44^low^ naive phenotype cells. **Conclusion:** The CXCR3 chemokine system is regulated by IFN‐α/β in CD8^+^ T cells, and it is critical for the efficient cell activation. The present study therefore reveals a novel role of the IFN‐α/β–CXCR3 signalling cascade in CD8^+^ T cell activation.
