The existence of co-transmitters of the sympathetic nervous system norepinephrine (NE) and ATP implies variations in the neuromodulator mechanisms of physiological processes. The role of ATP, as a transmitter of the peripheral part of sympathetic nervous system in the formation of thermoregulatory response is not clear. Whether ATP modulates any parameters(More)
Preliminary non-thermal activation of cold-sensitive TRPM8 ion channel facilitates initiation of the heat-defense responses in homoiothermal animals by decreasing temperature threshold of the vasodilatory response. TRPM8 activation leads to earlier heat-initiated increase in oxygen consumption, but reduces its magnitude. Warming inhibits the lipolytic(More)
In rats, the effect of activation of the cold- and menthol-sensitive TRPM8 ion channel on different thermoregulatory parameters: total oxygen consumption, carbon dioxide release, respiration coefficient, constriction response of skin blood vessels, muscle activity, was studied. Activation of TRPM8 with menthol even in thermoneutral conditions produces an(More)
Slight cooling had no effect on heat emission and heat production, but modulated the immune response to antigen in animals. Changes in the immune response upon rapid slight cooling of the skin (by 1.5°C) depended on the phase of immunogenesis corresponding to cold exposure. When cooling was performed immediately after immunization, antibody production(More)
Preliminary ionophoretic administration of Ca2+ ions into the skin prevents the inhibitory effects of deep cooling on some processes characterizing the immune response. Differently directed changes in some immune response parameters induced by exogenous calcium and deep cooling suggest that competitive interactions between calcium-dependent processes can(More)
Animal experiments were performed to study the effects of activation of cold- and menthol-sensitive TRPM8 receptors by menthol on thermoregulatory parameters in thermoneutral conditions and on cooling. Total oxygen consumption was measured, along with expiration of carbon dioxide, the respiratory coefficient, the skin vessel constriction reaction, and(More)
Mechanisms of maintenance of temperature homeostasis in warm and under effect of cold were studied in mice of AKR line and of its coherent line AKR.CBA-D13Mit76 with the changed gene i16 encoding the gp130 receptor via which IL-6 performs its action. Under thermoneutral conditions and under action of cold, there were recorded temperature parameters, total(More)
The role of thermosensitive TRP ion channels in physiological processes in the whole organism is far from being clear. In present work we tried to understand the possible participation of the cold-sensitive ion channel TRPM8 in regulation of the pro-inflammatory cytokine level in blood, and to see if hypertension (widely spread disease) changes this(More)
Involvement of various areas of the body surface in heat emission response to warming is characterized by a certain succession. The first response preceding the deep body temperature rise is dilation of ear skin vessels. Then, an increase in deep body temperature is counterbalanced by vascular reaction in the tail region, which plays the leading role in(More)
G protein-coupled 5-HT2A receptors are involved in the regulation of numerous normal and pathological physiological functions. At the same time, its involvement in the regulation of body temperature (Tb) in normal conditions is obscure. Here we study the effect of the 5-HT2A receptor activation or blockade on Tb in sick animals. The experiments were carried(More)
