Lymphocytes phenotypes are illustrated during HIV-1 infection and ART treatment. Humanized NSG mice were infected with HIV-1ADA, and after 10 weeks of infection, cellular phenotyping were detected by flow cytometry. a First, percentages of CD4+ and CD8+ T cells were determined from total human CD45+ CD3+ gate from blood, spleen and BM of uninfected, infected and infected and treated animal with two or four ART regimens. Results shown are at 10 weeks post HIV-1 infection. b Then spleen and BM CD4+ cells were investigated to determine the phenotype for TSCM, TCM, TEM and TREG populations in all the groups as explained in a. Cell suspensions were labelled with anti-human monoclonal antibodies (mAb) targeting the following cell-surface markers: CD45, CD3, CD19, CD4, CD8, CD25, CD127, CD45RA, CD45RO, CD95, CCR7 (all from BD Biosciences). Data shows the percentage of the specific human CD4+ cells population. c Schematic description of the frequencies of TSCM, TCM and TEM and TREG during HIV-1 infection and ART treatment in humanized mice. All acquisitions were performed on a LSRII flow cytometer (Beckman Coulter) and data were analysed by FlowJo software. a, b Comparisons of means (±SEM) for 4–9 mice per treatment group were determined by one-way ANOVA and pairwise significance by Fisher’s LSD post hoc test. P ≤ 0.05 compared with auninfected, binfected, or cinfected and treated with 2ART
