TRIGGERED ALARM RESPONSE. "Activation of TRPA1 can cause extreme irritation, lacrimation, coughing, bronchial contraction and depressed respiration. Therefore, potent electrophilic compounds (for example, 1-chloroacetophenone, dibenz[b,f][1,4]-oxazepine, 2-chlorobenzylidene malononitrile, and chloropicrin) are used as tear gases and riot control agents." https://lnkd.in/e-WBvC9 View in LinkedIn

EXTERNAL AND INTERNAL ALARM. "The TRPA1 ion channel (also known as the wasabi receptor) is a detector of noxious chemical agents encountered in our environment or produced endogenously during tissue injury or drug metabolism. These include a broad class of electrophiles that activate the channel through covalent protein modification." https://lnkd.in/evaGrBq View in LinkedIn

THERMOREGULATION. "TRP channels are expressed in thermoregulatory effector organs, such as adipose tissue, muscle, vasculature and gastrointestinal tract, thereby potentially modulating the metabolic status." https://lnkd.in/ekDF8xf View in LinkedIn

METABOLIC ROLE. "Since many TRP channels are functionally implicated in sensory systems, it is thus not surprising to discover their direct (or indirect) modulatory role in the context of metabolic regulation." https://lnkd.in/ekDF8xf View in LinkedIn

SENTINEL MOLECULE. "The non-selective cation channel TRPA1...is perhaps the most versatile of all polymodal sensory ion channels. Different TRPA1 orthologues were reported to mediate the detection of cold, heat and noxious chemicals, such as allyl isothiocyanate (AITC), the pungent agent from wasabi and other mustard plants." https://lnkd.in/eFfEp_R View in LinkedIn

MANY ACTIVATORS. "TRPA1 can also be activated by endogenous metabolic products and oxidative stress-derived substances and sensitized through G protein-coupled receptors (GPCRs), cyclic adenosine monophosphate/protein kinase A (cAMP/PKA), and protease activated receptor 2 (PAR2) signaling pathways." https://lnkd.in/ecaVp5Q View in LinkedIn

MANY ACTIVATORS. "TRPA1 is activated by a variety of chemical compounds, such as allyl isothiocyanate in mustard oil (MO), allicin in garlic and onion, and synthetic drugs such as clotrimazole, chlorpromazine, and clioquinol." https://lnkd.in/ecaVp5Q View in LinkedIn

RADS, ASTHMA, COPD. "In addition to directly activating a cough reflex, TRPA1 ligands may also be involved in the hypersensitization of cough and other sensory reflexes." https://lnkd.in/ey47aVM View in LinkedIn

CAPSAICIN LINK. "The capsaicin- and heat-activated non-selective cation channel TRPV1 exhibits robust temperature activation above 42°C in heterologous systems and primary neurons...TRPV1-deficient mice show complete loss of capsaicin sensitivity and significant reduction in the detection of noxious (≥50°C) heat stimuli and/or thermal hyperalgesia." Similarly, birds are oblivious to capsaicin. https://lnkd.in/eFfEp_R View in LinkedIn

DIVERSE ACTIVATORS AND OUTCOMES. "TRPA1 was found to be activated by a variety of chemical compounds, including mustard oil and cannabinoids. Subsequent studies identified additional ligands and revealed roles in pain, inflammation, itch, mechanical sensation, oxygen regulation, and more." https://lnkd.in/e-WBvC9 View in LinkedIn
