The mice were killed at intervals varying from 2 1/2-14 months postinoculation.

متن کاملReduced suppressor cell response to Mycobacterium leprae in lepromatous leprosy.

In this study, we demonstrated that the proportion of cells bearing the Leu8 antigen (associated with suppressor-inducer cells) is low in LL patients and tends to normalize during the erythema nodosum leprosum (ENL) episode. Antigen-induced suppressor ...
