 (c-f) Activation of the gB-specific CD8+ T cell hybridoma (as described in Fig. 1a) by macrophages incubated at 37 °C (c) or exposed to mild heat shock (d), IL-1β (e) or IFN-γ (f) and infected for 8 h with wild-type HSV-1 with the addition of DMSO (negative control), 3-methyladenine, bafilomycin, brefeldin A or MG-132 at 2 h after infection. Results in a,c-f are normalized to results obtained for CD8+ T cells stimulated with macrophages incubated with DMSO in each condition and are presented in arbitrary units. Data are from three independent experiments (mean and s.e.m. of triplicate samples).
