Caspase-8 comes in from the CYLD
摘要
The lethal effect of injection of the endotoxin, lipopolysaccharide, as a surrogate for sepsis, is known to require both Caspase-8 and Caspase-11 in mice. In this issue, Liu et al. provide compelling evidence that the cleavage of the de-ubiquitinase CYLD by Caspase-8 is required for Caspase-11 expression, thus providing the “missing link” for the role of Caspase-8 in endotoxicity.
