IL-2 and IL-7 differentially induce CD4-CD8- alpha beta TCR+NK1.1+ large granular lymphocytes and IL-4-producing cells from CD4-CD8- alpha beta TCR+NK1.1- cells: implications for the regulation of Th1- and Th2-type responses.

Abstract excerpt

Effector functions of CD4-CD8- double negative (DN) alpha beta TCR+ cells were examined. Among mouse DN alpha beta TCR+ thymocytes, NK1.1+ cells expressing a canonical V alpha 14/J alpha 281 TCR but not NK1.1- cells produce IL-4 upon TCR cross-linking and IFN-gamma upon cross-linking of NK1.1 as well as TCR. Production of IL-4 but not IFN-gamma from DN alpha beta TCR+NK1.1+ cells was markedly suppressed by IL-2....
