Fig 2. CD32 expression on CD4⁺ and CD4^dimCD8^bright T cells among HIV seronegative and seropositive donors.

a) CD32 expression on CD4^dimCD8^bright T cells and CD4⁺ T cells from HIV⁺ and HIV^- blood donors was evaluated by flow cytometry using peripheral blood of HIV seronegative (n = 4) and HIV seropositive (n = 11 donors). b) PBMCs from elite controllers (EC) (undetectable viral loads for >5 years) including one long term non-progressor (high viral load, CD4 > 500 cells/μL), cART adherent (viral load <40 copies/mL), and cART non-adherent/ treatment naïve (viremic) (viral load >10,000 copies/mL, CD4 count <500 cells/μL) donors were evaluated by flow cytometry for CD32 expression. c) Relationship between CD32 expression on CD4^dimCD8^bright T cells and CD4 count of HIV⁺ participants. Clinical CD4 counts taken on day of blood draw. * denotes p<0.05 determined by unpaired T-test and *** denotes p<0.01 as measured by paired T-test.
