How TNF regulates NK cell function and homeostasis is not fully understood. Here the authors investigate conditional knock out mice with TNFR1 and/or TNFR2 deficiency in NK cells upon bacterial infection, and identify that TNFR1 promotes cell death and impairs immunity while TNFR2 increases NK accumulation and enhances immunity.
