m6A-Modified NK Cells

Rapid Activation, Enhanced Effector Function

Engineered with rapid m6A methylation driven by the mTORC1-SAM axis, these NK cells activate faster and exhibit enhanced antitumor effector functions even in the tumor microenvironment.

Advantages

m6A methylation levels rapidly upregulated upon short-term NK-cell activation

Double knockout of METTL3/14 significantly impacts NK-cell antitumor immunity

Prf1 and Gzmb directly modified by m6A methylation

mTORC1 inhibition prevents m6A increase, restored by SAM supplementation
