Figure 3From: Induction of humoral and cellular immune responses against the HIV-1 envelope protein using γ-retroviral virus-like particlesFraction of total antigen specific splenocytes producing both IFN-γ and IL-2. All graphs show medians of results from five mice assayed in triplicate. Group medians were compared using the Mann-Whitney test * p < 0.05. All FLUOROspot results depicted represent antigen specific stimulation with background values (derived from unstimulated cells) subtracted.Back to article page
