NK depletion promotes development of M2 cells.
(A) Production of NO in the supernatant of restimulated CTL cultures. (B) Arginase activity in the adherent fraction of restimulated spleens that were cultured for 5 days. The concentrations are represented as quantity produced per 106 adherent cells. Mean values of 3 experiments (± SEM) are shown.
