title: Plasma cell generation inhibition in lymphocyte cultures containing cerebrospinal fluid from children with central nervous system viral infections.
abstract: Plasma cell generation in pokeweed mitogen-pulsed lymphocyte cultures was markedly suppressed when the experiments were carried out by adding cell-depleted cerebrospinal fluid (CSF) from 5 acute aseptic meningitis or meningoencephalitis children known to have an overexpanded cell population with the suppressor-cytotoxic T-cell surface phenotype in their CSF. In contrast, B-cell terminal differentiation was not affected by the addition of CSF from 5 control children with non-neurological diseases, thereby indicating that CSF from central nervous system virus-infected children contains soluble factors which are themselves capable of exerting regulatory influences on immunocompetent cells.
