RNA expression of reactivated Antigen-specific memory CD4 T cells previously exposed to tolerogenic or immunogenic stimulation
Ontology highlight
ABSTRACT: Activated and memory CD4 T cells play important roles in many autoimmune diseases often acting as upstream co-ordinators of inflammation and tissue destruction. A major therapeutic strategy is to turn off or tolerize these CD4 T cells thereby providing a cure. While much is understood about inducing tolerance in naïve CD4 T cells, little is known about whether or how to induce tolerance in previously activated or memory CD4 T cells. Here, we use RNA-sequencing to investigate the consequences of activating mouse CD4 memory T cells with antigen delivered in the absence of adjuvant, a classic tolerance-inducing strategy for naïve T cells. To examine the long term consequences of exposing memory CD4 T cells to tolerizing signals, we first reactivated them with antigen delivered with (control) or without (experimental) adjuvant, rested the cells and then reactivated them with antigen and adjuvant 5 days prior to isolating RNA for gene expression analysis.
