Mitochondria, pannexin-1 (panx1) channels, and P2X4 receptors congregate at the IS where mitochondria produce the ATP that panx1 channels release in order to stimulate P2X4 receptors. P2X4 receptor stimulation causes cellular Ca2+ influx that up-regulates mitochondrial metabolism and localized ATP production at the IS. Here we show that P2Y11 receptors are essential players that sustain these T cell activation mechanisms. We found that P2Y11 receptors retract from the IS toward the back of cells where their stimulation by extracellular ATP induces cAMP/PKA signaling that redirects mitochondrial trafficking to the IS. P2Y11 receptors thus reinforce IS signaling by promoting the aggregation of mitochondria with panx1 ATP release channels and P2X4 receptors at the IS. This dual purinergic signaling mechanism involving P2X4 and P2Y11 receptors focuses mitochondrial metabolism to the IS where localized ATP production sustains synaptic activity in order to allow successful completion of T cell activation responses. Our findings have practical implications because rodents lack P2Y11 receptors, raising concerns as to the validity of rodent models to study treatment of infections and inflammatory conditions."xsd:string |
