TRPV1 is found in dorsal root ganglia, brain, kidney, pancreas, testes, uterus, spleen, stomach, small intestine, lung and liver.
Functional Gastro-intestinal disorders
In an experimental mouse model of Eczema endocannabinoids AEA and PEA were increased and TRPV1 and PPARα were upregulated (Petrosino et al., 2010). PEA enhances AEA activity at CB1, CB2 and TRPV1 receptors and protects against keratinocyte inflammation in a TRPV1-, but not CB1, CB2 or PPARα-dependent way.
In mice, stimulating CB1 receptors (ACEA) or blocking TRPV1 receptors (capsazepine) protected against PTZ-induced seizures (Naderi et al., 2015). Interestingly, co-administration of both compounds attenuated the anti-convulsive effect, suggesting an interaction between CB1 and TRPV1 mediated signaling.
