title: Increased tendency to spontaneous in-vitro lymphocyte transformation in clinically active multiple sclerosis.
abstract: Lymphocytes from 8 of 10 patients with clinically active multiple sclerosis (MS) but from only 3 of 18 patients with quiescent MS and 4 of 20 healthy donors transformed spontaneously on in-vitro culture. The transformed cells from all donors had the characteristics of B lymphocytes (surface and intracytoplasmic immunoglobulin and complement receptors) and carried antigens of Epstein-Barr virus. It is suggested that these results are further evidence that immunoregulation in active MS is abnormal.
