ABSTRACT: The thermo-transient receptor potentials (TRPs), a recently discovered family of ion channels activated by temperature, are expressed in primary sensory nerve terminals where they provide information about thermal changes in the environment. Six thermo-TRPs have been characterised to date: TRP vanilloid (TRPV) 1 and 2 are activated by painful levels of heat, TRPV3 ... Continue Reading

STUDY: Fine-tuning of defensive behaviors in the dorsal periaqueductal gray by atypical neurotransmitters
ABSTRACT: This paper presents an up-to-date review of the evidence indicating that atypical neurotransmitters such as nitric oxide (NO) and endocannabinoids (eCBs) play an important role in the regulation of aversive responses in the periaqueductal gray (PAG). Among the results supporting this role, several studies have shown that inhibitors of neuronal NO synthase or ... Continue Reading
STUDY: “Redundancy” of Endocannabinoid Inactivation: New Challenges and Opportunities for Pain Control
ABSTRACT: Redundancy of metabolic pathways and molecular targets is a typical feature of all lipid mediators, and endocannabinoids, which were originally defined as endogenous agonists at cannabinoid CB1 and CB2 receptors, are no exception. In particular, the two most studied endocannabinoids, anandamide and 2-arachidonoylglycerol, are inactivated through alternative ... Continue Reading
STUDY: Cancer – Transient receptor potential (TRP) channels: a clinical perspective
ABSTRACT: Transient receptor potential (TRP) channels are important mediators of sensory signals with marked effects on cellular functions and signalling pathways. Indeed, mutations in genes encoding TRP channels are the cause of several inherited diseases in humans (the so-called ‘TRP channelopathies’) that affect the cardiovascular, renal, skeletal and nervous systems. TRP ... Continue Reading
STUDY: Cancer – Effects of cannabinoids and cannabinoid-enriched Cannabis extracts on TRP channels and endocannabinoid metabolic enzymes
BACKGROUND AND PURPOSE Cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) interact with transient receptor potential (TRP) channels and enzymes of the endocannabinoid system. EXPERIMENTAL APPROACH The effects of 11 pure cannabinoids and botanical extracts [botanical drug substance (BDS)] fromCannabis varieties selected to contain a more abundant cannabinoid, on TRPV1, ...
