Effect of repeated immobilization stress on the uptake of exogenous [3H]dopamine in adrenal chromaffin cells of mice.
Uptake of [3H]dopamine in adrenal chromaffin cells of the mouse during repeated immobilization was examined by autoradiography. Repeated daily immobilization of mice resulted in an increased uptake of [3H]dopamine to the level of denervated chromaffin cells. The increase was observed only in adrenaline-storing (A) cells, not in noradrenaline-storing (NA) cells. The results indicate that sympathetic outflow to the adrenal gland, especially to A cells, is ceased or blocked during the adaptation to stress.
