Profiles were generated using a panel of 50 monoclonal antibodies which primarily targeted lymphocyte populations and were distributed amongst 56 pools of four antibodies each. The key finding of this discovery-based study was that a population of CD8dimCD4– cells was reduced in frequency in both RR-MS and CIS patients.
