title: T and B lymphocytes and blastogenesis in leprosy.
abstract: T and B cell percentages and their blastogenic response to PPD and lepromin have been studied in 107 patients of various types of leprosy. T cell counts and their blastogenic response were found to be considerably lower in all types of leprosy as compared to the normal. The counts and stimulation were the lowest for lepromatous leprosy. B cell counts were unaltered in all types of leprosy.
