Kozyreva TV, Orlov IV, Boyarskaya AR, Voronova IP. Hypothalamic TRPM8 and TRPA1 ion channel genes in the regulation of temperature homeostasis at water balance changes. Neurosci Lett 2024; 828:137763. [PMID: 38574849 DOI: 10.1016/j.neulet.2024.137763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 03/28/2024] [Accepted: 03/29/2024] [Indexed: 04/06/2024]
Abstract
The role of the hypothalamic cold-sensitive ion channels - transient receptor potential melastatin 8 (TRPM8) and transient receptor potential ankyrin 1 (TRPA1) in homeostatic systems of thermoregulation and water-salt balance - is not clear. The interaction of homeostatic systems of thermoregulation and water-salt balance without additional temperature load did not receive due attention, too. On the models of water-balance disturbance, we tried to elucidate some aspect of these problems. Body temperature (Tbody), O2 consumption, CO2 excretion, electrical muscle activity (EMA), temperature of tail skin (Ttail), plasma osmolality, as well as gene expression of hypothalamic TRPM8 and TRPA1 have been registered in rats of 3 groups: control; water-deprived (3 days under dry-eating); and hyperhydrated (6 days without dry food, drinking liquid 4 % sucrose). No relationship was observed between plasma osmolality and gene expression of Trpm8 and Trpa1. In water-deprived rats, the constriction of skin vessels, increased fat metabolism by 10 % and increased EMA by 48 % allowed the animals to maintain Tbody unchanged. The hyperhydrated rats did not develop sufficient mechanisms, and their Tbody decreased by 0.8 °C. The development of reactions was correlated with the expression of genes of thermosensitive ion channels in the anterior hypothalamus. Ttail had a direct correlation with the expression of the Trpm8 gene, whereas EMA directly correlated with the expression of the Trpa1 gene in water-deprived group. The obtained data attract attention from the point of view of management and correction of physiological functions by modulating the ion channel gene expression.

Spatial summation of pain is associated with pain expectations: Results from a home-based paradigm. PLoS One 2024; 19:e0297067.

Abstract
The purpose of this study was to reproduce the previously observed spatial summation of pain effect (SSp) using non-laboratory procedures and commercial equipment. An additional aim was to explore the association between expectations and SSp. The Cold Pressor Task (CPT) was used to induce SSp. Healthy participants (N = 68) immersed their non-dominant hands (divided into 5 segments) into cold water (CPT). Two conditions were used 1) gradual hand immersion (ascending condition) and 2) gradual hand withdrawal (descending condition). Pain intensity was measured on a Visual Analogue Scale (VAS). Psychological factors, such as the participants' expectations of pain intensity were also measured on a VAS. Results showed significant SSp (χ2(4) = 116.90, p < 0.001), reproduced with non-laboratory equipment in a home-based set-up. Furthermore, two novel findings were observed: i) there was a significant correlation between expectations and perceived pain, indicating a link between pain expectations and SSp, ii) spatial summation increased with the increase in duration exposure to the noxious stimulus (Wald χ2(8) = 80.80, p < 0.001). This study suggests that SSp is associated with pain expectations and can be formed by a mixture of excitatory and inhibitory mechanisms potentially driven by temporal characteristics of neural excitation. Moreover, this study proposes a new feasible way to induce SSp using a home-based set-up.

Abstract
Analysis of the role of genomic regulation of systolic BP (SBP) in normal and hypertensive rats showed the presence of an inverse relationship between the level of Trpa1 gene expression in the anterior hypothalamus and SBP. Losartan, an antagonist of angiotensin II type 1 receptors, shifts it to the region of lower SBP and greater expression of the Trpa1 gene, which can attest to interaction of the TRPA1 ion channel in the anterior hypothalamus with angiotensin II type 1 receptors. No association was found between the expression of the Trpv1 gene in the hypothalamus and SBP. We have previously shown that activation of the peripheral ion channel TRPA1 in the skin also contributes to SBP decrease in hypertensive animals. Hence, activation of the TRPA1 ion channel both in the brain and at the periphery has similar effects on SBP and leads to its decrease.

Abstract
Cold exposure-induced secretion of stress hormones activates cold-defense responses and mobilizes substrates for increased energy demands to fuel thermogenesis. However, it is unclear whether acute cold exposure-induced stress hormone response kinetics affect circulating lipid parameter kinetics. Therefore, we aimed to investigate the 2-day kinetics of stress hormones (i.e., cortisol, epinephrine, and norepinephrine) and the lipid profile (i.e., total cholesterol [TC], high-density lipoprotein [HDL] cholesterol, low-density lipoprotein [LDL] cholesterol, and triglycerides) in response to whole-body long- (intermittent 170 min; 170-CWI) or short-duration (10 min; 10-CWI) cold-water immersion (CWI; 14 °C water) in 17 healthy, young, adult men. Both CWI trials induced a marked release of the stress hormones, epinephrine, and norepinephrine, with higher concentrations detected after 170-CWI (p < 0.05) and a disrupted diurnal peak of cortisol lasting for a few hours. 170-CWI increased triglyceride levels from immediately after until 2 h after CWI, thereafter the concentration decreased at 4 h, 6 h, 1 day and 2 days after CWI (p < 0.05). Furthermore, the HDL-cholesterol level increased immediately after and at 6 h after 170-CWI (p < 0.05), while TC and LDL-cholesterol levels were not altered within 2 days. Lipid parameters were not affected within the 2 days after 10-CWI. Although both CWIs decreased deep body temperature and increased stress hormone levels for a few hours, only long-duration CWI induced changes in the circulating lipid profile within 2 days after CWI. This should be considered when discussing therapeutic protocols to improve circulating lipid profiles and ameliorate diseases associated with such profiles.

Thermoregulatory Response to Cold at Various Levels of Activation of Peripheral TRPA1 Ion Channel. Bull Exp Biol Med 2021; 170:420-424.

Abstract
The effect of TRPA1-ion channel on thermoregulatory responses depending on the level of its activity was studied in Wistar rats. To activate the TRPA1 ion channel localized in the skin, its agonist allyl isothiocyanate (AITC) was used in different concentrations (0.04, 0.4, 1, and 2.5%). Low concentration of AITC (0.04%) enhanced and high concentrations (1 and 2.5%), on the contrary, inhibited cold-defense responses (decreased their magnitude and led to their later initiation due to an increase in temperature thresholds). With an increase in TRPA1 activation, the increase in temperature thresholds (afferent link) was ahead of the decrease in the magnitude of responses (efferent link), which can attest to different sensitivity of these processes to TRPA1 activation.

Abstract
The effects of pharmacological stimulation of skin ion channels TRPA1, TRPM8, TRPV1 on the immune response are presented. These effects are compared with the effects of different types of temperature exposures - skin cooling, deep cooling, and deep heating. This analysis allows us to clear the differences in the influence on the immune response of thermosensitive ion channels localized in the skin; (2) whether the changes in the immune response under temperature exposures are due to these thermosensitive ion channels. Experiments were performed on Wistar rats. For stimulation of TRPM8 ion channel, an application to the skin of 1% menthol was used, for TRPA1 - 0.04% allylisotiocianate, and for TRPV1 - capsaicin in a concentration of 0.001.The antigen binding in the spleen was two-times stimulated by activation of the cold-sensitive ion channel TRPM8 and much weaker by activation of warm-sensitive TRPV1 (by 15%), and another cold-sensitive ion channel TRPA1 (by 40%). Only the stimulation of TRPA1 significantly (by 140%) increased antibody formation in the spleen, while TRPM8 had practically no effect on this process, and activation of TRPV1 significantly (by 60%) inhibited antibody formation. Stimulation of the TRPM8 ion channel significantly (by 60%) reduced the level of IgG in the blood, which is believed to control of infectious diseases.The obtained results show that pharmacological activation of the skin TRPA1, TRPM8, TRPV1 ion channels can differently affect the immune system. At the epicenter of changes there were the antigen binding and antibody formation in the spleen, as well as the level of IgG in the blood. Exactly stimulation of the TRPM8 ion channel determines the changes in the immune response when only the skin is cooling, while at deep body heating, the changes in the immune response are mostly determined by the activation of the skin TRPV1 ion channel.

Abstract
The transient receptor potential ankyrin (TRPA) channels are Ca2+-permeable nonselective cation channels remarkably conserved through the animal kingdom. Mammals have only one member, TRPA1, which is widely expressed in sensory neurons and in non-neuronal cells (such as epithelial cells and hair cells). TRPA1 owes its name to the presence of 14 ankyrin repeats located in the NH2 terminus of the channel, an unusual structural feature that may be relevant to its interactions with intracellular components. TRPA1 is primarily involved in the detection of an extremely wide variety of exogenous stimuli that may produce cellular damage. This includes a plethora of electrophilic compounds that interact with nucleophilic amino acid residues in the channel and many other chemically unrelated compounds whose only common feature seems to be their ability to partition in the plasma membrane. TRPA1 has been reported to be activated by cold, heat, and mechanical stimuli, and its function is modulated by multiple factors, including Ca2+, trace metals, pH, and reactive oxygen, nitrogen, and carbonyl species. TRPA1 is involved in acute and chronic pain as well as inflammation, plays key roles in the pathophysiology of nearly all organ systems, and is an attractive target for the treatment of related diseases. Here we review the current knowledge about the mammalian TRPA1 channel, linking its unique structure, widely tuned sensory properties, and complex regulation to its roles in multiple pathophysiological conditions.
