Surface marker expression by small and large alveolar macrophages (AMs) from healthy HIV-1-uninfected participants. Bronchoalveolar lavage (BAL) cells were stained with anti-CD206 fluorescein isothiocyanate (FITC), anti-CD71 PE-Cy5, anti-HLA-DR Alexa fluor 700, anti-CD16 PE, anti-CD14 PE-Cy7, anti-CD11C PE, and anti-CD123 PE-Cy5, and analyzed by flow cytometry. (a) Proportions of small and large AMs expressing these surface markers. (b) The magnitude of surface marker expression by large and small AMs as measured by the geometric mean fluorescence intensity. Data were analyzed using the Wilcoxon matched-pairs signed-ranked test; black horizontal bars represent medians (HIV−, n=10).
