    There is enormous interest toward vanilloid agonists of the pain receptor TRPV1 in analgesic therapy, but the mechanisms of their sensory neuron-blocking effects at high or repeated doses are still a matter of debate. Our results have demonstrated that capsaicin and resiniferatoxin form nanomolar complexes with calmodulin, and competitively inhibit TRPV1-calmodulin interaction. These interactions involve the protein recognition interface of calmodulin, which is responsible for all of the cell-regulatory calmodulin-protein interactions. These results draw attention to a previously unknown vanilloid target, which may contribute to the explanation of the paradoxical pain-modulating behavior of these important pharmacons.
