Innate immune sensing of bacterial modifications of Rho GTPases by the Pyrin inflammasome
The Pyrin inflammasome detects the presence of a pathogen not through recognition of a microbial molecule but by the activity of a bacterial toxin that modifies host Rho activity.

Cysteine methylation disrupts ubiquitin-chain sensing in NF-κB activation
A conserved protein from enteropathogenic Escherichia coli, NleE, inhibits innate immune defence against infection by disrupting the NF-κB signalling pathway through methylation of ubiquitin-chain sensing protein...

The NLRC4 inflammasome receptors for bacterial flagellin and type III secretion apparatus
The inflammasomes are multiprotein complexes involved in innate immunity, and induce an immune response to pathogenic microbes by activating the caspase 1 protease. Two groups now report that the intracellular...
