title: [Effect of the cAMP-dependent phosphorylation of sheep erythrocyte membrane on their ability to induce a humoral immune response].
abstract: It was found that the immunization of mice with sheep red blood cells (SRBC) phosphorylated under conditions of cAMP synthesis induction led to a more than 3-fold decrease in the number of antibody-forming cells (AFC) in the mouse spleen as compared to control. Phosphorylation of SRBC led to a 2-fold and 3-fold reduction in the activity of cAMP-independent and cAMP-dependent protein kinases. It is assumed that the decreased immune response to phosphorylated SRBC is consequent on the inactivation of a certain percentage of SRBC antigenous determinants and that an important part in the recovery of their activity is played by the action of cAMP-dependent protein kinase membranes.
