Myeloid Cells TREM Down Anti-tumor Responses
In this issue of Cell, Molgora et al. and Katzenelenbogen, Sheban, Yalin, et al. highlight the novel role of TREM2 in shaping the immunosuppressive profile of tumor-associated myeloid cells and report that complementing immune-checkpoint therapy with TREM2 blockade induces stronger anti-tumor immune responses and reduces tumor growth.
