title: Proteases implicated in apoptosis: old and new.
abstract: OBJECTIVE
  The role of proteases in the regulation of apoptosis is becoming increasingly apparent. Whilst many of these proteases are already characterised, some have yet to be identified. Traditionally caspases held the traditional role as the prime mediators of apoptosis; however, attention is now turning towards the contribution made by serine proteases.
  
  
  RESULTS
  As unregulated apoptosis is implicated in various disease states, the emergence of this proteolytic family as apoptotic regulators offers novel and alterative opportunities for therapeutic targets.
  
  
  CONCLUSIONS
  This review presents a brief introduction and overview of proteases in general with particular attention given to those involved in apoptotic processing.
