title: Generation of phenotypic helper/inducer and suppressor/cytotoxic T-cell lines from cerebrospinal fluid in multiple sclerosis.
abstract: The investigation of cell-mediated events in man has been largely limited to the study of the cells in the peripheral circulation. The study of T cells from localized anatomic compartments has been difficult due to the small numbers of cells usually obtainable from these sites. Investigation of such compartmentalized responses theoretically may yield information relating to both normal immunoregulation and autoimmune diseases--information that may not be obtainable through the investigation of the circulating cellular immune system. Utilizing cerebrospinal fluid (CSF) lymphocytes from patients with multiple sclerosis as a model of compartmentalized immunologically relevant cells, the technology for the generation of long-term T-cell lines from compartments both in continuous culture and after cryopreservation and that consist of both helper/inducer and suppressor/cytotoxic phenotypes have been generated. The 10(4) to 10(5) CSF cells obtained initially from individual patients have often been expanded into greater than 10(8) total cells within 4 months. The ability to generate large, stable, cryopreservable helper and suppressor/cytotoxic T-cell lines from limited access compartments will allow for new investigative approaches into both normal immunoregulation and autoimmune diseases in man.
