^*P < 0·05 compared with contralateral popliteal lymph nodes (PLNc).

^†P < 0·05 compared with draining popliteal lymph nodes (PLNi), 2 days after inoculation with aMCMV [Smith's strain murine cytomegalovirus (MCMV), passaged three or four times through the rat fibroblast monolayer].

IFN-γ, interferon-γ; TNF-α, tumour necrosis factor-α.
