[Age aspects of receptor-effector reactions and the regulation of adenylate cyclase activity]

The present-day notions on the trends and mechanisms of changes in the activity of the cyclic nucleotide system are considered in the age aspect. Their role in disturbances of the neurohumoral regulation processes at the molecular level is discussed. Biochemical mechanisms of changes in the receptor-effector reactions are analyzed. An analysis of these changes is very important for elucidating general regularities of the cyclase system functioning with disturbances of biochemical regulation at the membrane and cell levels.
