T cell vaccination in secondary progressive multiple sclerosis
Four secondary progressive MS patients were vaccinated with bovine myelin-reactive irradiated T cell lines from their peripheral blood. Patients were followed for 30-39 months, and monitored for immunological responses toward the vaccine, and for their clinical characteristics. Two patients showed s...

All T cell lines lysed not only myelin-reactive T cells, but also TCL specific for MBP143-168, PLP104-117 and MOG43-55 peptides. Control TCL specific for tetanus toxoid were not lysed. Neutralizing anti-Fas mAb did not influence the killing. Moreover, culture supernatants from two TCL which produce IL-10, were able to block the proliferation of myelin protein-specific TCL. This effect was abrogated using mAbs specific for IL-10. The data obtained indicated that TCV using autologous irradiated bovine myelin-reactive T cells promotes an effective depletion of T cells reactive against different myelin antigens.
