Death of the septic monocyte: is more better?
Apoptosis is of pivotal importance in the pathogenesis of sepsis. Depending on the cell type involved and the time point of the disease process, apoptosis may be linked to either a good or a bad outcome. Work presented in this issue by Giamarellos-Bourboulis and coworkers suggests that an early increase in the apoptosis of blood monocytes is associated with improved survival in patients with varying degrees of sepsis. Although the mechanism by which monocyte apoptosis influences the outcome of sepsis cannot be determined by this study, these observations represent an important advance in our understanding of this complicated disease process.
