Abstract: | Summary The (Na++K+)- and Mg2+-dependent ATPase distribution in several brain areas has been investigated in Quaking mutant mice characterized by myelin deficiency. A marked decrease of (Na++K+)-ATPase activity has been found in limbic structures, hypothalamus and cerebellum. The Mg2+-dependent activity did not change. A possible involvement of the impairment of the (Na++K+)-ATPase activity in the seizure susceptibility of this mice is discussed.Chargée de Recherche au CNRS. |
