Figure Legend Snippet: Primary human CD4 T cells from eight different donors ( n = 8) were separately infected with lab‐adapted and primary HIV‐1 strains. Combined expression of DR4 and DR5 was assessed by flow cytometry 4 days after infection. Uninfected CD4 T cells were determined as CD4‐positive and HIV‐1 p24‐negative, infected cells as CD4‐negative and p24‐positive. Histograms (overlay) of one representative donor displaying combined DR4/5 surface expression on CD4 T cells previously incubated with NL4‐3, JR‐CSF, WITO, CH198, or CH236. Expression is displayed as fluorescence intensity ( x ‐axis). Comparison of the combined surface expression of DR4/5 between mock (white circles), uninfected (grey circles), and infected CD4 T cells (orange circles), from left to right: Mock: n = 8; NL4‐3: n = 8; JR‐CSF: n = 8; WITO: n = 7; CH198: n = 7; CH236: n = 8 (7–8 different donors per condition). Expression is displayed as relative fluorescence intensity (RFI) after normalization to the respective secondary AB‐only control ( y ‐axis). Data information: Wilcoxon signed‐rank test. Values for non‐infected and infected cells of the same donor are connected with lines. Source data are available online for this figure.
