[Dicarboxylic amino acids in brain proteins under conditions of sensitization with brain antigen]

Under conditions of the organism sensibilization with brain antigen there occur changes in amino acid composition of the brain protein fractions. The ratio of negatively charged amino acids to positively charged ones in sharply shifted towards predominance of the negative charge. A conclusion is made that such a brain protein modification activates acid peptide hydrolases and intensifies the sensibility of the proteins to these acid proteinases.
