[Role of T-, B-, null, suppressor lymphocytes and anti-brain antibodies in infectious-allergic disease of the nervous system].

Clinicoimmunologic studies involving 255 patients with infectious and allergic nervous disorders showed some alterations in their immune homeostasis in association with a certain imbalance in B-cell immunity. These changes were expressed in a decrease in the functional activity and absolute content of T-lymphocytes in the peripheral blood, in a steady increase in O-cells, and in insufficient lymphocyte T-suppressory control. The importance of elevated brain antibody levels for making the differential diagnosis of the autoallergic process in the nerve tissues is demonstrated.
