Programmed cell death: alive and well in the new millennium

Abstract

Research performed over the past decade has transformed apoptosis from a distinctive form of cell death known only by its characteristic morphology and genomic destruction to an increasingly well understood cellular disassembly pathway remarkable for its complex and multifaceted regulation. Here, we summarize current understanding of apoptotic events, note recent advances in this field and identify questions that might help guide research in the coming years.
