Double-label confocal images showing P2X2- with IP3R3-LIR in rat circumvallate taste buds. A: P2X2-LIR is present in nerve processes. Intense immunoreactivity can be seen in the nerve plexus near the basal lamina (BL). B: Type II taste cells displaying IP3R3-LIR. C. Double-label image showing P2X2-LIR nerve processes in close apposition with IP3R3-LIR taste cells (C1 and C2). C3 indicates an IP3R3-LIR cell that is enveloped by a P2X2-LIR nerve process. TP: taste pore, Scale bar = 20 μm.
