White blood cells called neutrophils have an unappreciated role in eradicating solid tumors, according to a surprise discovery from a team led by Weill Cornell Medicine scientists.

In the study, published March 30 in Cell, the researchers investigated how a T cell-based immunotherapy was able to destroy melanoma tumors even though many of the tumor cells lacked the markers or “antigens” targeted by the T cells...
