Role of Adenosine 2A Receptors (A2AR) on regulatory T cells (Tregs). Mus musculus

The adenosine 2A receptor (A2AR) is expressed on regulatory T cells (Tregs), but the functional significance is currently unknown. We compared the gene expression between wild-type (WT) and A2AR knockout (KO) Tregs and between WT Tregs treated with vehicle or a selective A2AR agonist. Overall design: FACS-sorted GFP positive Tregs from WT or A2AR KO FoxP3GFP mouse spleen and lymph nodes were incubated 18 hr with vehicle (DMSO), a separate set of WT Tregs were incubated with the selective A2AR agonist ATL1222 10 nM (Dogwood Pharmaceuticals, Inc.) for 18 hr prior to RNA isolation.
