Detection of innocuous temperatures allows an organism to select an appropriate environmental climate, while the ability to recognize noxious temperature extremes warns of impending tissue damage. For temperatures considered cold, the menthol receptor TRPM8 is activated when temperatures drop below ~26°C, thus making it an intriguing candidate as the molecular mediator of cold perception. Howev...

Abstract Mechanical algesia is an important process for the preservation of living organisms, allowing potentially life-saving reflexes or decisions when given body parts are stressed. Yet, its various underlying mechanisms remain to be fully unraveled. Here, we quantitatively discuss how detection painful mechanical stimuli by human central nervous system may, partly, rely on thermal measureme...

CONCLUSION It is suggested that TRPV1, 2, 3, and 4, TRPM5 and 8, and TRPA1 may play several roles in the olfactory epithelium (OE), contributing to olfactory chemosensation, olfactory adaptation, olfactory–trigeminal interaction, and OE fluid homeostasis. In patients with olfactory disturbance, TRPV1 and TRPM8 may be closely related to a high rate of recognition of curry and menthol odors, whil...

Background and structure Transient receptor potential vanilloid receptor 1 (TRPV1) is one of 6 members of the subfamily of vanilloid receptors that belongs to the family of transient receptor potential (TRP) channels. TRP channels are an intrinsic part of the mammalian sensory system responding to a broad range of stimuli such as temperature, touch, pain, osmolarity, pheromones, and taste (8). ...

The transient receptor potential (TRP) channels are important membrane sensors, responding to thermal, chemical, osmotic, or mechanical stimuli by activation of calcium and sodium fluxes. In this study, three distinct TRP channels were detected and their role established in mediating cytosolic free calcium concentration ([Ca(2+)](cyt)) response in tumor-derived SW982 synoviocytes and primary cu...
