Article Title: HIV-Specific B Cell Frequency Correlates with Neutralization Breadth in Patients Naturally Controlling HIV-Infection
doi: 10.1016/j.ebiom.2017.05.029
Figure Lengend Snippet: In HLA-B*57 + ECs, the frequency of HIV-specific B cells correlates with the neutralization of tier-2 T/F virus. (a) Association of HIV gp140-specific B cell frequency (among IgG + B cells) and percent of neutralization for all HIV strains tested (top panel) or T/F HIV strains (bottom panel) for all ECs (Total EC), HLA-B*57 + and HLA-B*57 − ECs. (*) p < 0.05. (b) Spearman correlation matrices between the frequency of gp140- and gp41-specific B cell of various IgG isotypes and the percentage of neutralized strains (All strains) or T/F strains and the frequency of Env-specific B cell of various IgG subtypes. Left panel HLA-B*57 + and right panel HLA-B*57 − ECs. Strength and significance are represented as size and color intensity: blue for positive correlation and red for negative correlation. The numbers are p values.
Article Snippet: Cell viability was evaluated using LIVE/DEAD® (ThermoFisher Scientific) and the following Abs were used: CD19-APCCy7 (SJ25C1), CD21-APC (B-ly4), CD27-PE (M-T271), IgD-PECF594 (IA6-2), IgG-BV605 (G18-145), CD38-V450 (HB7) (all from BD biosciences), IgM-AF700 (CH2, Exbio) and IgG2-AF488 (HP6002, Southern Biotech).
