Ruthenium red blocks the capsaicin-induced increase in intracellular calcium and activation of membrane currents in sensory neurones as well as the activation of peripheral nociceptors in vitro
In a number of sensory neuron preparations, Ruthenium red (RR) selectively attenuated the response to capsaicin. First, RR (100 nM) reversibly abolished capsaicin but not bradyk...
