Abstract Shigellosis (bacillary dysentery) is an acute enteric infection caused by members of Shigella genus. It causes annual deaths of approximately five million children in developing countries. Among Shigella spp., S. flexneri causes more serious forms of dysentery than other Shigella species. Due to the appearance of multidrug-resistant strains of Shigella spp., it is...

Activation of the innate immune receptor NLRP1B leads to the formation of an inflammasome, which induces autoproteolytic processing of pro-caspase-1, and ultimately to the release of inflammatory cytokines and to the execution of pyroptosis. One of the signals to which NLRP1B responds is metabolic stress that occurs in cells deprived of glucose or treated with metabolic inhibitors. NLRP1B might...

Enterohemorrhagic Escherichia coli (EHEC) is a diarrheagenic pathogen that colonizes the gut mucosa and induces attaching-and-effacing lesions. EHEC employs a type III secretion system (T3SS) to translocate 50 effector proteins that hijack and manipulate host cell signaling pathways, which allow bacterial colonization and subversion of immune responses and disease progression. The aim of this...

The second messenger cyclic di-GMP is almost ubiquitous among bacteria and so are the cyclic di-GMP turnover proteins, which mediate the transition between motility and sessility. EAL domain proteins have been characterized as cyclic di-GMP-specific phosphodiesterases. While most EAL domain proteins contain additional, usually N-terminal, domains, there is a distinct family of proteins within...
