The potency of broadly neutralizing antibodies (bNAb) in the HIV-1 infected men who have sex with men (MSM) and injecting drug user (IDU) participants of the Amsterdam Cohort. Serum samples from MSM (n = 299) and IDUs (n = 85) from the Amsterdam Cohort Studies on HIV-1 infection and AIDS (ACS) were screened for the capability to neutralize six viruses from different HIV-1. (A) Comparison of bNAb responses in MSM (gray data points) and IDUs (black data points). Each data point represents one individual’s geometric mean ID50 titer (GMT) across the six-virus panel. (B) Same as A, but with the IDU separated in men (square) and women (triangle). Each data point represents one individual’s GMT. Statistically significant differences between the different cohorts were determined using a Mann–Whitney t-test and the respective P-values are shown. Horizontal bars represent the median values per group.
