[Biochemical studies on histones of the central nervous system. II. Acetylation of histones from neurons and glia of the rat brain in vitro].

There are no qualitative differences in the electrophoretic patterns of histones from neurones and glia. A 25% increased acetylation rate is found in neuronal histones as compared to glial histones after incubation of chopped brain in a [14C]-acetate containing medium. This result probably reflects different condensation states of the chromatins of both cell types, as demonstrated by electron microscopy.
