Cryo-EM structures of type IV pili complexed with nanobodies reveal immune escape mechanisms

Nature Communications
Type IV pili (T4P) are prevalent, polymeric surface structures in pathogenic bacteria, making them ideal targets for effective vaccines. However, bacteria have evolved efficient strategies to evade type IV pili-directed antibody responses.

Diachronic Development in Isolation: The Loss of V2 Phenomena in Cimbrian [PDF]

, 2007
This paper deals with the syntactic development of Cimbrian, a German dialect, which was spoken for centuries in some enclaves in northern Italy. In particular, we argue that the ‘dismantlement’ of the V2 phenomenon is connected with a change concerning ...

The response regulator FpsR controls the flagella–pili transition and mucosal colonization in Ligilactobacillus ruminis

Gut Microbes
Ligilactobacillus ruminis is a flagellated lactic acid bacterium found in the intestines of various mammals, including humans. Although this species harbors a complete flagellar gene cluster, flagella formation has not been observed in human-derived ...

Electron Transfer in the Biogeochemical Sulfur Cycle

Life
Microorganisms are key players in the global biogeochemical sulfur cycle. Among them, some have garnered particular attention due to their electrical activity and ability to perform extracellular electron transfer.

To be or not to be a cytochrome: electrical characterizations are inconsistent with Geobacter cytochrome ‘nanowires’

Frontiers in Microbiology
Geobacter sulfurreducens profoundly shapes Earth’s biogeochemistry by discharging respiratory electrons to minerals and other microbes through filaments of a two-decades-long debated identity. Cryogenic electron microscopy has revealed filaments of redox-
