- P2YGi receptor agonists inhibit depolarization-evoked Ca++ transients in sensory neurons at 5 minutes after application. Table shows the percentage of sensory neurons in wild type and P2Y1-/- mice inhibited by each agonist and the magnitude of inhibition (change in peak response); values are given as mean ± SEM. Data are given for all sensory neurons, as well as for capsaicin-responsive cells (TRPV1+).
