Neutral sphingomyelinases restrict natural killer cells activity against lung cancer
Blocking a lipid-regulating enzyme boosts natural killer cell activity against lung cancer in lab models, warranting further testing.
Inhibition of neutral sphingomyelinases enhanced NK cell activation, lipid raft stability, and infiltration of lung adenocarcinoma in preclinical models, proposing sphingomyelinase inhibitors as a novel immunotherapy enhancer. This is a preclinical finding that requires in vivo validation before clinical translation.
