Caspases
U ncontrolled lymphoproliferation is a characteristic feature of lymphomas and leukemias. Nonmalignant lym-phoproliferative diseases are also observed in humans as well as in lpr (lymphoproliferation) and gld (generalized lymphad-enopathy) mice. The discoveries that spontaneous mutations of Fas (APO-1/CD95) or its ligand (FasL) were associated with the lpr and gld phenotypes led to a satisfying...
متن کاملDeath without caspases, caspases without death.
Apoptosis is a conserved cell-death process displaying characteristic morphological and molecular changes including activation of caspase proteases. Recent work challenges the accepted roles of these proteases. New investigations in mice and the nematode Caenorhabditis elegans suggest that there could be caspase-independent pathways leading to cell death. In addition, another type of cell death...

متن کاملDo plant caspases exist?
Programmed cell death (PCD) is a functional concept that refers to cell death that is part of the normal life of a multicellular organism; it involves controlled disassembly of the cell. In animal systems PCD is synonymous with apoptosis, a cell death process characterized by a distinct set of morphological and biochemical features, mediated by a class of specific Cys proteases called cysteinyl...
متن کاملAre metacaspases caspases?
The identification of caspases as major regulators of apoptotic cell death in animals initiated a quest for homologous peptidases in other kingdoms. With the discovery of metacaspases in plants, fungi, and protozoa, this search had apparently reached its goal. However, there is compelling evidence that metacaspases lack caspase activity and that they are not responsible for the caspaselike acti...
