Complementary mechanisms of lenalidomide and rituximab induce immune‐mediated cytotoxicity in FL tumour cells. Lenalidomide single‐agent resulted in increased Natural Killer (NK)cell (orange) and T cell (blue) activation and proliferation and enhanced immune synapse formation, leading to apoptosis of follicular lymphoma (FL) cells (grey). Rituximab treatment of target FL cells led to NK cell–mediated antibody‐dependent cellular cytotoxicity (ADCC) of FL cells. Combining lenalidomide with rituximab resulted in enhancement of tumour apoptosis through complementary mechanisms.
