Apoptosis

Apoptosis plays a central role in the regulation of cell proliferation. Disruption of this control mechanism may cause serious human diseases such as encephalomyelitis and cancer. Thus, understanding of the molecular mechanisms of apoptotic cell death should lead to fundamental advances in the therapy of these diseases.
