Mice that received WT or LIGHT−/− CD8 T cells in Fig 1 were analyzed on day 6 and 8 post-infection. (A-E) Lung cells were stained extracellularly with antibodies to CD8, Vα2, Vβ5, CD44, CD25, CD69, CXCR3, CD62L, IL7Rα (CD127); (B) intranuclearly with Ki67; (C) intracellularly with antibodies to TNF, IFNγ following re-stimulation with SIINFEKL peptide during which CD107α was added; and (D) intra-nuclearly with antibodies to t-bet, eomes, blimp1, pStat5, without peptide re-stimulation.
