Rhesus Macaque Acute SIV Infection Study

Question Addressed: How does Simian immunodeficiency virus (SIV) infection alter gene expression in memory CD4 T cell subsets very early during the 1st 10 days after infection? Memory CD4 T cells were sorted from rhesus macaque peripheral blood samples before infection and then at 4 and 10 days post SIV infection. RNA was recovered from the sorted memory CD4 T cells samples. RNA from the time point prior to SIV infection from each individual animal was used as the reference for the post SIV infection time points for that same animal. Thus, for each data set, the 4 and 10 day time points are being directly compared to the pre-infection data from the same animal. RNA samples as indicated above were used for reverse transcription reactions that directly incorporate Cy5 and Cy3 labeled nucleotides into the cDNA. Time: Time after infection with SIV time series design
