[The humoral immunity characteristics of women with neurotic depressions].

The levels of autoantibodies and their anti-idiotypes to proteins of nervous tissue (S100b, GFAP, MP65 and nerve growth factor) were studied in 85 women of 18-48 years of age with psychogenic neurotic depressions. It was found that the changes of the levels of autoantibodies to the proteins of nervous tissue correspond to various somatoautonomic manifestations and correlate with severity of depression, its typological variations and duration of the disease. The data obtained show a close relationship between nervous and immune systems that was expressed by some parallelism of the dynamics of the changes of both neurotic depressive symptoms and serum immunoreactivity to neuroantigens.
