| Abstract: | Cerebrospinal fluid (CSF) cells from 4 mumps meningitis and 11 multiple sclerosis (MS) patients were cultured in vitro for 7 days with and without pokeweed mitogen (PWM) stimulation. The cells produced varying amounts of IgG without stimulation and no significant increase of IgG synthesis was observed after PWM stimulation. Antibodies against mumps, measles, rubella, herpes simplex, and adeno viruses were measured in the supernatants of the cultures by a sensitive enzyme immunoassay. In the mumps meningitis patients, the largest amount of antibody was against mumps virus but low amounts of antibodies with other specificities were also synthesized by CSF cells of one patient. The most commonly detected specificities in MS patients were against measles and rubella viruses, whereas antibodies against adeno and mumps viruses were detected in only one CSF cell supernatant. No antibodies produced against herpes simplex virus in vitro were detected in any of the supernatants. The amounts of viral antibodies produced in vitro and intrathecally were only partially correlated. |
