• The effect of a new immunosuppressant, FK506, on experimental allergic neuritis (EAN) was examined in Lewis rats. EAN was induced by inoculation with bovine peripheral myelin. The EAN rats were divided into two groups. FK506-treated EAN rats were prophylactically administered FK506 by injection into the peritoneal cavity at a dosage of 5.0 mg/kg/day for 13 days beginning the day after inoculation. The control EAN rats were injected with only saline solution. FK506 prevented the development of EAN, histologically and clinically. In FK506-treated EAN rats, flow cytometric analysis of T cell subsets of the lymph nodes showed a significant decrease in W3/13 positive T cells on the 14th and 21st day and a decrease in W3/25 positive T cells on the 21st day after inoculation when compared with the control EAN rats. The percentage of OX-8 positive T cells were not significantly different between the two groups. Our results suggest that FK506 prevented the development of EAN by decreasing W3/13 and W3/25 positive T cells.(Internal Medicine 31 : 6-10, 1992)
