[The nature of serum factor precipitating autologous alpha-globulins in rabbits].

The nature of serum factor, resulted from the immune response to human albumin being a precipitant of auto-alpha-globulins in rabbits, have been studied. The use of ion exchange, immunoaffinity chromatography and immunoelectrophoresis has shown, that antibodies to human albumin, carrying the binding site to alpha-globulin in antigen-binding fragment are the factor responsible for alpha-globulin precipitation. The synthesis of antibodies cross-reacting to alpha-globulin gives the evidence of the selective derangement of tolerance to one of organism self antigens during the immune response to heterologous antigen.

[The characteristics of the autoimmune reactions in donors immunized with influenza vaccine and staphylococcal anatoxin].

Regularities in the formation of autoantibodies to human IgA, IgM, IgG and their fragments, such as F(ab')2, Fab, Fc, in donors immunized with influenza vaccine (44 subjects) and staphylococcal toxoid (15 subjects) were studied with regard to the dynamics of specific immune response. After immunization with staphylococcal toxoid autoimmune reactions were registered only in the precipitation tests during 3-5 weeks of observation. In donors immunized with influenza vaccine the induction of isotypically heterogeneous autoimmune reactions was established. These reactions were represented mainly by IgA and IgG autoantibodies to immunoglobulins of different classes and their fragments. The duration of autoimmune reactions registered in this group of donors was specially noteworthy. The levels of autoantibodies to most of the antigens under study remained significantly elevated for 6 months. After immunization with influenza vaccine the presence of direct correlation between the level of specific immune response and the level of autoantibody formation was established.
