Important paper by Björn Corleis. For decades a central tenet of #tuberculosis immunology has that IFNγ-driven iNOS expression in macrophages is the primary mechanism of bacterial control. Turns out this is really only in mice and maybe cattle. It’s not true in most species including humans an NHP.
