The specific AchE (EC 18.104.22.168) activity of lymphocytes from the peripheral blood of normal donors was determined. On Leukopak filter the isolated T lymphocytes showed activity, whereas in stepwise Percoll gradient, population TLD displayed enzyme activity. The THD and B cells were inactive. [Szelényi J. G., Bartha E. & Hollán S. R. (1982) Br. J. Haemat. 50, 241]. A mixed cell population derived from CLL patients had significantly lower enzyme activity than normal. With the progress of B-cell proliferation AchE activity decreased in parallel with the number of T cells. The sp. act. of TLD population isolated from CLL patients was the same as that of normal donors whereas their B cells were inactive.
