Immune responses in macaques (N = 4 per group) following four intradermal immunizations with NLC formulations containing the equivalent of 64 µg p24 and 253 µg CpG. a Specific antibodies and b IFN-γ-producing T lymphocytes. Individual macaques are represented by circular, triangular, square or diamond-shaped markers. Dashes represent the mean for each group, and bars indicate the standard error of the mean. Arrows below the X-axis indicate immunizations. Data were compared between groups base on a 2-way ANOVA test followed by Holm–Sidak method. ***p < 0.001; **p < 0.01; * p < 0.05 between NLC–p24+ NLC+ /CpG group and others
