title: HLA antigens and mitogen responsiveness in multiple sclerosis.
abstract: Thirty-one MS patients were studied for their in vitro response to lymphocyte mitogens. Patients with HLA antigens A3 and/or B7 had lower mean peak responses to all three mitogens compared to A3, B7-negative patients. The difference in the mean peak responses to Con A were significantly different at a level of p less than 0.05. This supports the concept of a histocompatibility-linked T-cell deficiency in many patients with MS.
