[Change in acid phosphatase and N-acetyl-beta-glucosaminidase activity in mouse lymphocytes induced by concanavalin...

The treatment with concanavalin A (5 micrograms/ml) of mouse lymphocytes containing 70-72% of T cells entails an increase in the activity of acid phosphatase and a decrease in the activity of N-acetyl-beta-glucosaminidase. These changes were detectable 15 h after lymphocyte incubation with Con A. After 24 h of incubation acid phosphatase activity rose 2-fold whereas that of N-acetyl-beta-glucosaminidase dropped 45-50%. Possible mechanisms of these changes are discussed.
