Figure 2From: TRPV1 antagonists attenuate antigen-provoked cough in ovalbumin sensitized guinea pigsIntracellular Ca2+ in response to capsaicin (0.1 μM) was measured in isolated guinea pig nodose ganglia neurons and expressed as 334/380 ratio change. When cells were preincubated with BCTC, capsaicin-induced Ca2+ response was inhibited in a concentration dependent manner. * p < 0.05 compared with control (n = 5–12).Back to article page
