Abstract:
This paper presents the new priority data on the effect of genetically determined deficiency of endogenous vasopressin on the functioning of V2 receptor in the plasma membrane of the principal cells of the collection ducts of Brattleboro rats. It was found that 2-day desmopressin administration results in the activation of V2 receptor gene expression in Brattleboro rat, whereas in Wistar rats the content of mRNA did not change. In addition, short-term exposure of the collection ducts of the kidneys to the hormone led to V2 receptor internalization from the plasma membrane in Wistar rats, but had no effect on the protein content in Brattleboro rats.

Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
