DC frequencies in Ad-SIV immunized group are positively correlated with antigen-specific T and B cell responses in rectal mucosa. Non-parametric Spearman test was performed for correlation analysis by using the data obtained after 1st Ad-SIV (A–C) and 2nd Ad-SIV (D–F) immunizations. Frequencies of Ad-SIV immunized rectal DCs were measured at day 3 after each immunization. Rectal antigen-specific T and B cell responses in Ad-SIV group were measured at day 21 after each immunization. SIV Gag, SIVM766 Env, or SIVCG7V Env peptide pools as indicated were used for 6 h of T cell stimulation. The antigen-specific responses are reported following subtraction of unstimulated values.
