Novel strategies for characterizing T Cell responses in SIV-infected rhesus monkeys

[摘要] (cont.) One of the challenges in studying mucosal cellular immunity is the limited number of cells available in biopsies, making traditional assay systems such as flow cytometry very difficult to employ. Here, technologies for isolating rare cell populations and extracting RNA from these cells for gene expression analysis were developed. These technologies were then applied to peripheral blood specimens, looking at gene expression differences between virus-specific CD8+ T cells in Mamu-A*01+ and Mamu-A*02+ monkeys. The ultimate goal of these studies is to gain a better understanding of SIV immunopathogenesis (as a model for HIV immunopathogenesis) and to find a way to control or eliminate the virus.
