Likewise, we observed in mouse models of lymphoma, that mice with a T cell-specific deletion of <i>Hdac7</i> harbor impaired anti-tumor immune responses in syngeneic transfer models of lymphoma and we found that HDAC7 is required for CD8<sup>+</sup> T cell-dependent memory recall responses in models of lymphocytic choriomeningitis virus infection. This evidence concerns the gene CD8A and lymphoma.
