Quorum Sensing of Periodontal Pathogens

open access: yesActa Stomatologica Croatica, 2015
The term ‘quorum sensing’ describes intercellular bacterial communication which regulates bacterial gene expression according to population cell density. Bacteria produce and secrete small molecules, named autoinducers, into the intercellular space.

The Influence of Motility on Bacterial Accumulation in a Microporous Channel [PDF]

open access: yesSoft Matter, 2020, Advance Article, 2020
We study the transport of bacteria in a porous media modeled by a square channel containing one cylindrical obstacle via molecular dynamics simulations coupled to a lattice Boltzmann fluid. Our bacteria model is a rod-shaped rigid body which is propelled by a force-free mechanism.

Production, reproduction, and reversion of protoplast-like structures in the osmotic strain of Neurospora crassa [PDF]

open access: yes, 1958
Protoplasts devoid of cell walls have been produced in Bacillus megaterium and certain other Gram-positive species of bacteria.(1) Structures resembling protoplasts but not completely devoid of cell walls have also been produced in Escherichia coli and ...

Sortase enzymes in Gram‐positive bacteria [PDF]

open access: yesMolecular Microbiology, 2011
SummaryIn Gram‐positive bacteria proteins are displayed on the cell surface using sortase enzymes. These cysteine transpeptidases join proteins bearing an appropriate sorting signal to strategically positioned amino groups on the cell surface. Working alone, or in concert with other enzymes, sortases either attach proteins to the cross‐bridge peptide ...

The immunological interface: dendritic cells as key regulators in metabolic dysfunction‐associated steatotic liver disease

open access: yesFEBS Letters, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Swimming statistics of cargo-loaded single bacteria [PDF]

open access: yesarXiv, 2020
Burgeoning interest in the area of bacteria-powered micro robotic systems prompted us to study the dynamics of cargo transport by single bacteria. In this paper, we have studied the swimming behaviour of oil-droplets attached as a cargo to the cell bodies of single bacteria.

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms

open access: yesFEBS Letters, EarlyView.
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...
