Figure Lengend Snippet: FIGURE 1 | Experimental design and correlation of viral loads with engraftment levels. (A) Illustrates the experimental design for the generation of hCD34+ humanized mice, HIV infection, groups implemented and the tissues harvested for the study. The time point for the tissue harvest reflects chronic infection. Representative flow cytometric dot plot of mouse blood-stained for human CD45-PerCP and mouse CD45-FITC used to identify successfully engrafted animals. The 2 × 2 design for female and male mice is indicated. (B) Correlation analyses between measured variables %hCD45+ cells (at time of engraftment) and viral loads (at study endpoint) for each mouse in the four HIV-infected groups. The Spearman coefficients (rs) indicated, while positive, did not reach significance (P < 0.05) in any of the groups. F-HIV-Opn+ n = 5, F-HIV-Opn– n = 9, M-HIV-Opn+ n = 8 and M-HIV-Opn– n = 5.
Article Snippet: Tissues were evaluated at the study endpoint to validate and quantify human leukocytes by seven-color flow cytometry with a cocktail containing the following antibodies: human pan-CD45-Viogreen or PerCP (Miltenyi Biotec), 130-110-638, ThermoFisher (MHCD4531), CD3-PE (ThermoFisher, MHCD0304), CD4-Vioblue (Miltenyi Biotec, 130-113-219), CD8-APC-Vio770 (Miltenyi Biotec, 130- 113-155), CD14-APC (BioLegend, 301808), CD19-FITC or PerCP (eBiosciences, 11-0199-42; BioLegend, 302228) and mouse CD45-FITC (eBiosciences, 11-0451-82).
