Type IV Pili in Thermophilic Bacteria: Mechanisms and Ecological Implications [PDF]

Biomolecules
Type IV pili (T4P) machinery is critical for bacterial surface motility, protein secretion, and DNA uptake. This review highlights the ecological significance of T4P-dependent motility in Thermus thermophilus, a thermophilic bacterium isolated from hot ...

Visualization of Type IV Pili: Linking Structural Architecture, Dynamic Function, and Translational Opportunities [PDF]

Biology
Type IV pili are widespread and multifunctional filamentous nanomachines that contribute to bacterial motility, adhesion, surface sensing, DNA uptake, biofilm formation, and, in some organisms, extracellular electron transfer.

Beyond movement: the dynamic roles of Type IV pili in cyanobacterial life [PDF]

Journal of Bacteriology
Type IV pili are versatile prokaryotic cell appendages that are extremely widespread in the bacterial and archaeal domains of life. The structure, dynamics, and functions of type IV pili have been most intensively studied in several species of ...

Structural basis of Acinetobacter type IV pili targeting by an RNA virus [PDF]

Nature Communications
Acinetobacters pose a significant threat to human health, especially those with weakened immune systems. Type IV pili of acinetobacters play crucial roles in virulence and antibiotic resistance.

Type IV Pili of Streptococcus sanguinis Contribute to Pathogenesis in Experimental Infective Endocarditis [PDF]

Microbiology Spectrum, 2021
Streptococcus sanguinis is a common cause of infective endocarditis (IE). Efforts by research groups are aimed at identifying and characterizing virulence factors that contribute to the ability of this organism to cause IE.

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

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.

Type IV Pili Can Mediate Bacterial Motility within Epithelial Cells [PDF]

mBio, 2019
Pseudomonas aeruginosa is among bacterial pathogens capable of twitching motility, a form of surface-associated movement dependent on type IV pili (T4P). Previously, we showed that T4P and twitching were required for P.

Subcellular localization of type IV pili regulates bacterial multicellular development [PDF]

Nature Communications, 2022
Bacteria can form organized multicellular communities through regulation of cell growth, motility, shape and differentiation. Here, Ellison et al. show that bacterial multicellular development can also be driven by specific patterns of localization of ...
