[Kallikrein inhibition of the expression of the lymphocyte E rosette receptor. Prevention of this effect by alpha-2-macroglobulin].

In vitro Kallikrein inhibits the expression of lymphocytes-E-rosetting-receptor. The preincubation of alpha-2-macroglobulin with Kallikrein prevents this effect quickly. The incubation with alpha-2-macroglobulin of Kallikrein pretreated-lymphocytes is ineffective.
