Figure 4. Peripheral human γδ T cells predominantly express the A2a, P2X1, P2X4, P2X7, and P2Y11 receptor subtypes.

Total RNA isolated from >98% pure γδ T cells was subjected to qPCR using primers specific for the 19 known human purinergic receptor subtypes. Analyses were performed in triplicate, and mRNA expression levels of individual receptors were normalized to β-actin. Data shown are averages ± sd; n = 3.
