Calico finds new target for sensitizing leukemia to NK cells
Calico Life Sciences LLC (South San Francisco, Calif.) showed in an eLife paper that blocking DCAF15, an adaptor for E3 ubiquitin ligase substrates, could boost the sensitivity of leukemia to antitumor NK cell activity. DCAF15 deletion upregulated the lymphocyte costimulatory molecule CD80 in chronic myelogenous leukemia (CML) cells, resulting in amplified cell death when cocultured with NK cells. Reduced DCAF15 was associated with increased
