Abstract:
Correlation between the relative magnitude of activity or concentration in youth and the relative magnitude of age-related decrease occurs in several systems. We have observed this correlation in density of D2-dopamine receptors of the striatal membrane, activity of lymphocyte activated killer cells, relative density of CD8 on thymocytes, augmenting activity of T splenocytes and mRNA, coding for IL-1 in Langerhans cells. We have suggested that this correlation should be considered in the context of balanced investment in lifespan and reproductive efficiency, that it may be the result of feedback regulation and have designated it as "economic correction".
