Four types of kidney projecting sensory neurons based on capsaicin reactivity. Traces are representative recordings obtained from each type of neuron. A: repeated applications of capsaicin (CAP; 1 μM) cause TRPV1 desensitization. B: in the second type of neuron, TRPV1 is not desensitized by repeated applications of capsaicin. C: in the third type of neuron, capsaicin does not induce a TRPV1 response until after pretreatment with ATP (100 μM). D: capsaicin does not cause a TRPV1 response, even after ATP pretreatment. Responses are representative of recordings obtained from 189 kidney projecting sensory neurons.
