[Programmed cell death: history and future of a concept].
Cell death was observed and understood since the 19th century, but there was no experimental examination until the mid-20th century. Beginning in the 1960's, several laboratories demonstrated that cell death was biologically controlled (programmed) and that the morphology was common and not readily explained (apoptosis). By 1990 the genetic basis of programmed cell death had been established and the first components of the cell death machinery (caspase 3, bcl-2 and Fas) had been identified, sequenced, and recognized as highly conserved in evolution. The rapid development of the field has given us substantial understanding of how cell death is achieved. However, capitalizing on our knowledge for therapeutic purposes requires us to learn much more about how a cell commits to death, as well as recognizing that apoptosis may be the most common and efficient means of death, but that there are alternative pathways that can result in cell death even when the conventional pathway is blocked. Interestingly enough, many of the arguments and missteps in the history of the field were anticipated by Claude Bernard, and his warnings and recommendations remain valid today.
