Role of IFN-γ in LDV-mediated protection against AB1 growth. a Survival of groups of 8 BALB/c mice either uninfected (open circles) or infected with LDV one day before tumor administration, without (closed circles) or with (open triangles) anti-IFN-γ treatment, was monitored daily after i.p. administration of AB1 cells. b Proliferation of AB1 and P815 cells was measured after 3 days of culture in the presence of serial IFN-γ doses. Results for triplicate measurement are shown as means ± SEM. ***: significant differences when compared to cultures without IFN-γ (p < 0.001)
