Antibrain antibodies in mental disorder: no evidence for antibodies against synaptic membranes.
Antibody reactivity in serum to synaptic membranes from human was investigated in major depressive disorder (N = 20), paranoid schizophrenia (N = 20), schizoaffective psychosis (N = 20), and in controls (N = 20) using Western and Immunoblots and ELISA technique. None of the patients showed a significant immune response to synaptic membranes. There was a base-line activity in both controls and patients with antibodies directed to a double band of proteins at 66kD. These antibodies may represent natural autoantibodies. The authors conclude from this and other studies that there is at present no proof of antibrain antibodies in mental disorder.
