miRNAs play an important role in regulating CD8+ T cell response. We used the microarray approach to profile the miRNA signatures of naïve, day 5 effector, day 8 effector, and memory CD8+ T cells. We identified a miRNA signature associated with rapidly proliferating effector CD8+ T cells. CD8+ T cel...

During acute viral infections, effector CD8+ T cells differentiate into memory precursors or short-lived terminal effectors. miR-17-92a over-expression skews CD8+ effector cells to the terminal differentiation. We used microarray to identify the genes that are differentially expressed caused by miR-...

T cell dysfunction is an important feature of many chronic viral infections. In particular, it was shown that PD-1 regulates T cell dysfunction during chronic LCMV infection in mice and PD-1 high cells exhibit an intense exhausted gene signature. These findings were extended to human chronic infecti...

Analysis of the gene expression profiles of naïve B cells, resting memory B cells (MBCs), activated B cells (ABCs) and antibody-secreting cells (ASCs) isolated from peripheral blood one week following influenza vaccination. Upon antigen exposure B cells eventually bifurcate into two distinct lineag...

CD4 T follicular helper (Tfh) cells provide the required signals to B cells for germinal center reactions that are necessary for longlived antibody responses. However, it remains unclear whether there are CD4+ memory T cells committed to the Tfh lineage after antigen clearance. Using adoptive transf...

Understanding the response of memory CD8 T cells to persistent antigen re-stimulation and the role of CD4 T cell help is critical to the design of successful vaccines for chronic diseases. However, studies comparing the protective abilities and qualities of memory and naïve cells have been mostly pe...
