We have previously shown that in T cells the PI3-K inhibitor , wortmannin , interferes with activation of the mitogen-activated kinase , Erk2 , after T cell receptor ( TcR ) stimulation .
 ( protein: TcR, None) , ( protein: Erk2, None) , ( cell type: T cells, None) , ( protein: T cell receptor, None) , ( protein: PI3-K, None) , ( protein: mitogen-activated kinase, None)
