[Lymphotoxin production by human lymphocytes. III. The action of adenovirus antigen]

Abstract

In lymphocyte cultures (LC) from 5 immune donors blast transformation occurred as a result of the stimulting action of adenovirus antigen; the supernatants obtained from these cultures produced a cytotoxic effect on L cells, thus suggesting the presence of lymphotoxin (LT). No blast transformation and no LT production were detected in nonstimulated LC used for control, as well as in LC from 9 nonimmune donors. LT production was shown to depend on the time elapsed after recovery from acute adenovirus infection. LT production was found to be most intensive during the first 2 months after recovery.
