Description

Xin Li and colleagues report 2026 findings on a tissue-resident natural killer cell group in non-small cell lung cancer, the most common lung cancer type. Natural killer cells normally kill tumor cells, yet this group, marked by CD49a, behaved in a suppressive way. The team studied surgical samples with single-cell gene readings.

Tumors rich in these cells responded poorly to therapy given before surgery and held fewer tertiary lymphoid structures, small immune hubs linked to better outcomes. The cells showed high checkpoint genes, low killing genes, and high CSF-1 output. That signal pushed macrophages toward a healing M2 state that favors tumors. Blocking this group could improve pre-surgery therapy.
