Abstract

Circulating lymphocytes were isolated from normal individuals and from patients with IM. IM lymphocytes synthesized RNA at 10 times the rate of normal lymphocytes. A 1-hour exposure to PHA did not result in the stimulation of 4 to 30S RNA synthesis which occurs in a similarly treated normal lymphocyte. RNA synthesis in IM lymphocytes actually appeared to be depressed by this short exposure to PHA.
