Our paper on the in situ structure of the Tad pili machine is now published in mBio journals.asm.org/eprint/D9AT2... #microsky
Investigating the Tad pilus nanomachine in a genetically tractable, non-pathogenic organism like Caulobacter crescentus provides a powerful model for elucidating the architecture and functional dynamics of this widespread system. Insights gained from studying the Tad machinery can improve our understanding of related Tad pilus systems in pathogenic bacteria such as Aggregatibacter actinomycetemcomitans, where Tad pili are a key determinant of biofilm formation and chronic infection. Additionally, the remarkable functional diversity of Tad systems, ranging from surface sensing in C. crescentus to bacterial predation in Myxococcus xanthus, highlights their broad biological relevance. By revealing the in situ architecture of the Tad pilus biosynthetic machinery, this study advances our understanding of a major class of bacterial nanomachines and may thus provide structural insights that could inform the development of new therapeutic strategies targeting pilus-mediated virulence.
Great collaboration with @guo-lab.bsky.social to determine an in situ architectural model of the Tad pilus machine. Be on the lookout soon for a preprint on the same topic by Grant Jensen and @viollierpat.bsky.social. #microsky
