Webb4 maj 2000 · The hallmark of T-cell activation is the production of interleukin 2 (IL-2). c-Jun amino-terminal kinase (JNK), a MAP kinase that phosphorylates c-Jun and other … WebbThis process leads to the production of many millions of T cells that recognise the antigen. In order to control the response, stimulation of CD28 by B7 induces the production of CTLA-4 (CD152). This molecule competes with CD28 for B7 and so reduces activation signals to the T cell and winds down the immune response.
