2. Figure 1
Representative flow cytometry profiles of the expression of five antigens on alveolar macrophages of an HIV-positive patient. Solid lines=FITC-conjugated specific monoclonal antibody; dotted lines=negative isotype control; AM Dot Plot=forward-sideward scatter plot of the total AM population analyzed with outgated lymphocytes (see Methods section).

3. Figure 2
Relative linear median fluorescence intensities (RLMFI) (y-axis) for HLA-DR, DP, and DQ in AMs for controls (C) and HIV-infected patients (HIV+). Single values and mean±SEM. Solid points=smokers; circles=nonsmokers. Any value of RLMFI ≤1 indicates absence of specific antigen expression. HLA-DP for smoking HIV-infected patients vs smoking controls: 9.6±1.3 (n=17) vs 6.0±1.1 (n=7), p=0.04; for nonsmoking HIV-infected patients vs nonsmoking controls: 18.8±3.3 (n=7) vs 7.7±1.7 (n=3), p=0.02. HLA-DR for smoking HIV-infected patients vs smoking controls: 23.1±4.1 (n=18) vs 18.0±3.7 (n=7), p=0.39; for nonsmoking HIV-infected patients vs nonsmoking controls: 67.5±11.8 (n=9) vs 48.9±14.2 (n=5), p=0.26. HLA-DQ for smoking HIV-infected patients vs smoking controls: 2.7±0.4 (n=15) vs 2.4±0.4 (n=7), p=0.78; for nonsmoking HIV-infected patients vs nonsmoking controls: 4.3±0.4 (n=9) vs 3.8±1.1 (n=6), p=0.35.

4. Figure 3
Relative linear median fluorescence intensities (RLMFI) (y-axis) for CD11c, CD11b, and CD14 in AMs from controls (C) and HIV-infected patients (HIV+). Single values and mean±SEM. Solid points=smokers; circles=nonsmokers. Any value of RLMFI ≤1 indicates absence of specific antigen expression. CD11c for smoking HIV-infected patients vs smoking controls: 8.4±1.1 (n=17) vs 5.1±1.1 (n=7), p=0.04; for nonsmoking HIV-infected patients vs nonsmoking controls: 10.3±2.4 (n=6) vs 4.1±1.4 (n=3), p=0.05. CD11b for smoking HIV-infected patients vs smoking controls: 2.6±0.4 (n=12) vs 1.7±0.3 (n=7), NS; for nonsmoking HIV-infected patients vs nonsmoking controls: 5.5±1.1 (n=5) vs 1.6±0.7 (n=2), p=0.05. CD14 for smoking HIV-infected patients vs smoking controls: 2.0±0.4 (n=17) vs 1.2±0.3 (n=7), p=0.02; for nonsmoking HIV-infected patients vs nonsmoking controls: 2.2±0.5 (n=6) vs 0.5±0.1 (n=3), p=0.02.

5. Figure 4
Relative linear median fluorescence intensities (RLMFI) (y-axis) for CD13 and CD33 in AMs from controls (C) and HIV-infected patients (HIV+). Single values and man±SEM. Solid points=smokers; circles=nonsmokers. Any value of RLMFI ≤1 indicates absence of specific antigen expression. CD33 for smoking HIV-infected patients vs smoking controls: 1.6±0.1 (n=15) vs 1.1±0.2 (n=6), p=0.05; for nonsmoking HIV-infected patients vs nonsmoking controls: 1.9±0.3 (n=4) vs 0.8±0.3 (n=2), p=0.05.

Relative linear median fluorescence intensities (RLMFI) (y-axis) for CD71 in AMs from controls (C) and HIV-infected patients (HIV+). Single values and mean±SEM. Solid points=smokers; circles=nonsmokers. Any value of RLMFI ≤1 indicates absence of specific antigen expression.

7. Figure 6
Representative flow cytometry profiles of CD11b antigen expression on large (left) and small (right) AMs taken from an HIV-positive patient. Red area=FITC-conjugated specific monoclonal anti-CD11b-antibody. Black background area=negative isotype control. Fluorescence intensity of large AM was 2.5, and that of small AM was 6.6 RLMFI units (see Methods section).
