Figure 1From: Identification of new HIV-1 Gag-specific cytotoxic T lymphocyte responses in BALB/c miceTat broadens T cell responses against HIV-1 Gag. Mice were immunized with Gag alone, with Gag in combination with Tat protein, or with PBS alone. After 3 immunizations, fresh splenocytes were tested by IFNγ Elispot assay using 15 amino acid long peptides encompassing the entire Gag sequence. Positive responses to the indicated peptides are represented in the Figure.Back to article page
