Med Poster1992

The Nobel Prize in Physiology or Medicine 1992

Activation of the immune system in response to a specific antigen illustrates how a series of protein phosphorylation and dephosporylation reactions convert a cell surface event to changes in DNA transcription and cell replication. A protein phosphatase in the lymphocyte is activated (when contacting the antigen-presenting cell)

	Lymphocytes divide and the immune system is activated
