Thermosensing in hypothalamic osmoregulatory circuits
, 2013 L'homéostasie physiologique est maintenue par l'activation de réponses autonomes et comportementales via l'activité de neurones situés dans l'hypothalamus antérieur. Plus spécifiquement, les cellules magnocellulaires neurosécrétoires (CMNs) situés dans les noyaux périventriculaire et supraoptique relâchent la vasopressine (VP), une hormone peptidique ...

Thermosensory Roles of G Protein-Coupled Receptors and Other Cellular Factors in Animals. [PDF]
BioessaysRecent studies have revealed GPCR functions in temperature sensation. This article introduces dual thermosensing via GPCRs and TRP channels associated with the intracellular signaling components and cellular factors such as lipid interactions and pH changes, highlighting the complexity of the temperature sensing mechanism.

The effect of mutation in the stem of the MicroROSE thermometer on its thermosensing ability: insights from molecular dynamics simulation studies. [PDF]
RSC Adv, 2022 A large number of bacteria have been found to govern virulence and heat shock responses using temperature sensing RNAs known as RNA thermometers (RNATs).

Intra- and inter-session reliability and repeatability of an infrared thermography device designed for materials to measure skin temperature of the triceps surae muscle tissue of athletes [PDF]
PeerJ, 2023 Background Infrared thermography devices have been commonly applied to measure superficial temperature in structural composites and walls. These tools were cheaper than other thermographic devices used to measure superficial human muscle tissue ...

TRP channels in thermosensation
Current Opinion in Neurobiology, 2022 The ability to sense external temperature is assumed by somatosensory neurons, in which temperature information is converted to neural activity by afferent input to the central nervous system. Somatosensory neurons consist of various populations with specialized gene expression, including thermosensitive transient receptor potential ion channels ...

Thermosensation and longevity [PDF]
Journal of Comparative Physiology A, 2015 Temperature has profound effects on behavior and aging in both poikilotherms and homeotherms. To thrive under the ever fluctuating environmental temperatures, animals have evolved sophisticated mechanisms to sense and adapt to temperature changes. Animals sense temperature through various molecular thermosensors, such as thermosensitive transient ...

Thermosensory TRPV Heterotetramers Drive Seasonal Polyphenism: Molecular Basis of CcIav/CcNan-PKCα-AKH/AKHR Signaling in Pear Psyllid Morph Transition. [PDF]
Adv Sci (Weinh)At 2 5 °C, thermal activation initiates: i) CcIav/CcNan heterotetramer assembly → Ca2⁺ influx; ii) CcPKCα phosphorylation → AKH signaling potentiation; iii) CcAKH1 binding to membrane‐localized CcAKHR → energy mobilization (lipid catabolism/glycogenolysis) and vitellogenin transport via follicular patency; iv) Oocyte maturation → summer‐form nymph ...

The physiological role of TRP channels in sleep and circadian rhythm. [PDF]
J Cell Mol MedAbstract TRP channels, are non‐specific cationic channels that are involved in multiple physiological processes that include salivation, cellular secretions, memory extinction and consolidation, temperature, pain, store‐operated calcium entry, thermosensation and functionality of the nervous system.

The Cellular Code for Mammalian Thermosensation [PDF]
The Journal of Neuroscience, 2013 Mammalian somatosenory neurons respond to thermal stimuli and allow animals to reliably discriminate hot from cold and to select their preferred environments. Previously, we generated mice that are completely insensitive to temperatures from noxious cold to painful heat (−5 to 55°C) by ablating several different classes of nociceptor early in ...

Engineering vanilloid-sensitivity into the rat TRPV2 channel
eLife, 2016 The TRPV1 channel is a detector of noxious stimuli, including heat, acidosis, vanilloid compounds and lipids. The gating mechanisms of the related TRPV2 channel are poorly understood because selective high affinity ligands are not available, and the ...
