MYC and lymphoma: We further corroborated the requirement of NK cells in slowing down T-lymphoma growth by injecting intravenously luciferase-labeled MYCON T-lymphoblasts derived from an SRα-tTA/tet-O-MYC mouse (Supplementary Fig. 21) into recipients with (NOD SCID) or without (NOD SCID IL-2Rγ−/−, NSG) NK and other innate lymphoid cells.
