Effects of cadmium on the uptake of dopamine and norepinephrine in rat brain synaptosomes

Cadmium (Cd) a known environmental contaminant is neurotoxic. Kinetics of cadmium inhibition indicate that the metal may compete with ATP and Na/sup +/ sites on Na/sup +/-K/sup +/ ATPase in rat brain synaptosomes. Uptake and release processes of catecholamines into the central nervous system are dependent on membrane bound Na/sup +/-K/sup +/ ATPase. It is suggested that the uptake and release processes of dopamine (DA) and norepinephrine (NE) in neurons are energy utilizing and hence are dependent on active ion transport. If the two aforementioned mechanisms are truly interdependent, then any alteration caused by a toxin to either of the above two mechanisms should also cause a parallel change in the other. The purpose of this study was to examine in vitro effects of cadmium chloride on the uptake of DA and NE and the activity of ATPase in the rat brain synaptosome.
