[Effect of antisynaptosome antibodies on the metabolism of synaptosomal proteins]

The authors studied the effect of intraventricular injection of antisynaptosomal gamma-globulin on the protein of synaptosomal proteins in the rat brain cortex. The effect was assesed according to the protein specific radioactivity 2 and 3 hours after injection into animals of 14C-protein hydrolysate of Chlorella. Injection of antisynaptosomal gamma-globulin provoked an increase and reduction in the specific radioactivity of the proteins under study 2 and 3 hours, respectively, after labeled precursor injection. It is assumed that interaction of synaptosomal antibodies with protein synaptosomal antigens produces intense decay of antigens, leading to activation of their synthesis.
