B-Lymphocyte Alloantigens Associated with Systemic Lupus Erythematosus

Abstract
We examined B-lymphocyte alloantigens in 41 patients with systemic lupus erythematosus and 184 controls, using a panel of 47 pregnancy serums, and compared reaction frequencies of individual serums. One serum, la-715, reacted with B lymphocytes from 75.6 per cent of patients and 14.1 per cent of controls (Pccc<0.03) were increased in systemic lupus erythematosus.
