Characterization of markers of SIV susceptibility. A-G, Vaginal lymphocytes from uninfected, acutely and chronically SIVmac251-infected RMs were stained by CD3, CD4, CD8, CCR5, CCR6 and Ki-67. B-G, All cells analyzed were gated on the live CD4+CD8-CD3+ cell populations. Bars indicate the mean. H, Vaginal tissue from animal EB11 was stained for SIV antigens Gag (Green) and Env (Red), and Ki-67 (Red or Blue in inset) to measure whether SIV infected cells were actively dividing. Scale bars measure 10µm unless indicated. I-J, The frequency and MFI of CCR6+ cells was measured on the CD4 T cell population after 5 days of infection. PBMC from uninfected RMs were cultured with or without SIVmac251. Box plots indicate the median and interquartile range. * p < 0.05.
