TRPV1 is part of the transient receptor potential family and is one of the non-GPCR cannabinoid receptors. TRPV1 is involved in thermoregulation and pain detection (nociception).

Chemical Name: 
Transient receptor potential cation channel subfamily V member 1/Vanilloid receptor 1.
IUPHAR entry: 
Wikipedia entry: 

TRPV1 is found in dorsal root ganglia, brain, kidney, pancreas, testes, uterus, spleen, stomach, small intestine, lung and liver.

Literature Discussion: 


Anandamide anti cancer properties depend on TRPV1 and not on CB1 or CB2 (Contassot et al., 2004; Ramer and Hinz, 2008).


Bone Cancer

Research shows that bone cancer cells express TRPV1 receptor  (Kawamata et al., 2010). 

Cervical Cancer

cannabinoid receptors CB1CB2 and TRPV1 are expressed in the cervix (Ayakannu et al., 2015).


CBD modulates Id-1 gene and targets receptors CB1, CB2, TRPV-1 and TRPV-2 (Solinas et al., 2013; Soroceanu et al., 2013)


OEA reduced food intake and weight gain in rodents via PPARα and TRPV1 (Overton et al., 2006).

Functional Gastro-intestinal disorders

Apart from CB1 and CB2, there is evidence for the involvement of PPARγ and TRPV1 in Crohn’s Disease (de Fontgalland et al., 2014; Schicho and Storr, 2014)

CB1 and TRPV1 signaling are both required for the development of stress-induced visceral hyperalgesia and TRPV4 and TRPA1 may also be involved (Lin et al., 2013).


In a rat study, Anandamide was found to induce bladder inflammation pain through TRPV1 suggesting this receptor might be a therapeutic target (Dinis et al., 2004).


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 CB1CB2 and TRPV1 receptors and protects against keratinocyte inflammation in a TRPV1-, but not CB1CB2 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.
