Abstract :

Rats injected intravenously with monoclonal antibodies reactive with brain acetylcholinesterase (AChE) developed a prolonged depression of plasma AChE without changes in butyrylcholinesterase, lactic acid dehydrogenase, or hematocrit. One antibody, ZR1, accumulated in the brain and spinal cord. Within 3 days of injection, ZR1 bound to most of the AChE in cerebral cortex and certain other regions of the CNS. Examination of the molecular forms of cortical 10S AChE, whereas 4S AChE remained free. In vitro, however, ZR1 bound equally to solubilized 4S and 10S forms. These data provide direct evidence for the compartmentalization of different AChE forms in the CNS, 10S being mainly extracellular and 4S apparently intracellular. Development of a striking and persistent bilateral ptosis within hours of injection suggests that AChE in the autonomic nervous system is also accessible to antibodies and, furthermore, is the site of an immunopathological lesion. This novel model of cholinergic autoimmunity may have relevance for human neurological disorders of unknown etiology.
