1 NAD+ and ATP released from injured cells induce P2X7-dependent shedding of CD62L and externalization of phosphatidylserine by murine T cells. NAD purinergic receptor P2X, ligand-gated ion channel, 7 Mus musculus
2 Although ATP acts as a soluble ligand to activate P2X(7), gating of P2X(7) by NAD(+) requires ecto-ADP-ribosyltransferase ART2.2-catalyzed transfer of the ADP-ribose moiety from NAD(+) onto Arg125 of P2X(7). NAD purinergic receptor P2X, ligand-gated ion channel, 7 Mus musculus
3 Although ATP acts as a soluble ligand to activate P2X(7), gating of P2X(7) by NAD(+) requires ecto-ADP-ribosyltransferase ART2.2-catalyzed transfer of the ADP-ribose moiety from NAD(+) onto Arg125 of P2X(7). NAD purinergic receptor P2X, ligand-gated ion channel, 7 Mus musculus

7 Steady-state concentrations of NAD(+) and ATP in extracellular compartments are highly regulated and usually are well below the threshold required for activating P2X(7). NAD purinergic receptor P2X, ligand-gated ion channel, 7 Mus musculus
8 We show that lysis of erythrocytes releases sufficient levels of NAD(+) and ATP to induce activation of P2X(7). NAD purinergic receptor P2X, ligand-gated ion channel, 7 Mus musculus
9 We further show that the routine preparation of primary lymph node and spleen cells induces the release of NAD(+) in sufficient concentrations for ART2.2 to ADP-ribosylate P2X(7), even at 4 degrees C. Gating of P2X(7) occurs when T cells are returned to 37 degrees C, rapidly inducing CD62L-shedding and PS-externalization by a substantial fraction of the cells. NAD purinergic receptor P2X, ligand-gated ion channel, 7 Mus musculus
