Abstract:
:Recognition of peptidoglycan is integral to detection of gram-positive bacterial pathogens. In a recent issue of Cell, Wolf et al. (2016) report that detection of the N-acetylglucosamine component of peptidoglycan by the glycolytic enzyme hexokinase activates the NLRP3 inflammasome, revealing an intriguing interplay between pathogen detection and metabolism.

评论,杂志文章abstract::Type III secretion systems (T3SS) are used by bacteria to deliver proteins into the cytoplasm of eukaryotic cells. Most studies of T3SS have focused on the role of these secretion systems in specific host interactions. However, there is increasing evidence to suggest that T3SS are also used in interactions with multip...
