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 کاملCaspases: the executioners of apoptosis.
Apoptosis is a major form of cell death, characterized initially by a series of stereotypic morphological changes. In the nematode Caenorhabditis elegans, the gene ced-3 encodes a protein required for developmental cell death. Since the recognition that CED-3 has sequence identity with the mammalian cysteine protease interleukin-1 beta-converting enzyme (ICE), a family of at least 10 related cy...
متن کاملCaspases: the enzymes of death.
The caspases are a unique family of cysteine proteases, which cleave proteins next to an aspartate residue. Among all known mammalian proteases, only the serine protease granzyme B has similar substrate specificity. In addition to a central role of caspases in the initiation and execution phases of apoptosis, these enzymes have some other non-apoptotic functions in living cells. During apoptosi...
