Control of dM HIV-1 infection by dNK cells. dMs were infected with HIV-1BaL at an MOI of 10−3. dNK cells were added to dMs after the infection at a ratio 1 dM:5 dNK. Viral production was followed by the quantification of the p24 Ag in the supernatants collected every 3 or 4 days. a The mean of the p24 Ag concentration in dM supernatants (circle symbol and full line) and in coculture supernatants (square symbol and dotted line) of 23 donors is displayed over time. Bars indicate standard error of the mean. b The percentage of inhibition of the p24 Ag production was calculated at day 20 post-infection. The mean of 23 donors is displayed on the graph. Each symbol represents one individual donor. The viral production in dMs cultured alone and in coculture with dNK cells were compared. The sign-rank test for paired data was used. **p < 0.005; ***p < 0.0005
