Additional file 2: of Association between different anti-Tat antibody isotypes and HIV disease progression: data from an African cohort

magnitude of anti-Tat humoral responses: (A) Anti-clade B and C Tat IgG, IgA or IgM titers were determined in anti-Tat positive sera and displayed for every donor. (B) Heatmap showing, for single donors, positivity (black) or negativity (grey) towards clade C or clade B Tat for each isotype. (C) Optical density (O.D.) from screening ELISA tests are shown for each donor after cut-off subtraction. Cut-off values were included in the following ranges: 0.128 ± 0.029 for anti-clade C Tat IgG; 0.1245 ± 0.042 for anti-clade B Tat IgG; 0.1177 ± 0.022 for anti-clade C Tat IgA; 0.1387 ± 0.031 for anti-clade C Tat IgA; 0.1963 ± 0.060 for anti-clade C Tat IgM; 0.370 ± 0.086 for anti-clade B Tat IgM.

Expression of systemic T cell activation markers in relation to infection with different helminth species.

<p>The frequencies of HLA-DR⁺CD38⁻ and total HLA-DR⁺ (B) are shown on the y-axis for CD4 (left panels) and CD8 T cells (right panels). The worm infection status is indicated on the x-axis stratified into worm negative individuals or those infected with TT (<i>Trichuris trichiura</i>), SH (<i>Schistosoma haematobium</i>), SM (<i>Schistosoma mansoni</i>), AL (<i>Ascaris lumbricoides</i>) or HW (Hookworm). Statistical analysis was performed using Mann-Whitney test for comparing groups. Shown in (C) is a linear regression analysis between the frequency of HLA-DR⁺/CD38⁺ CD8 T cells and the worm egg counts (as measured by Kato-Katz method) within Trichuris (left panel) and <i>S. mansoni</i> (right panel) infected subjects.</p
