Pseudomonas aeruginosa differentiates substrate rigidity using retraction of type IV pili

Matthias Koch, Endao Han, Joshua Shaevitz, Zemer Gitai,

The ability of eukaryotic cells to differentiate substrate stiffness is fundamental for many processes such as the development of stem cells into mature tissue. Here, we establish that bacteria feel their microenvironment in a similar manner. We show that Pseudomonas aeruginosa actively probes and measures substrate stiffness using type IV ... Read more >>

Competitive binding of independent extension and retraction motors explains the quantitative dynamics of type IV pili.

Matthias D Koch, Chenyi Fei, Ned S Wingreen, Joshua W Shaevitz, Zemer Gitai,

Type IV pili (TFP) function through cycles of extension and retraction. The coordination of these cycles remains mysterious due to a lack of quantitative measurements of multiple features of TFP dynamics. Here, we fluorescently label TFP in the pathogen <i>Pseudomonas aeruginosa</i> and track full extension and retraction cycles of individual ... Read more >>

Pseudomonas aeruginosa detachment from surfaces via a self-made small molecule.

Robert J Scheffler, Yuki Sugimoto, Benjamin P Bratton, Courtney K Ellison, Matthias D Koch, Mohamed S Donia, Zemer Gitai,

Pseudomonas aeruginosa is a significant threat in both healthcare and industrial biofouling. Surface attachment of P. aeruginosa is particularly problematic as surface association induces virulence and is necessary for the ensuing process of biofilm formation, which hampers antibiotic treatments. Previous efforts have searched for dispersal agents of mature biofilm collectives, but ... Read more >>
