Heterologously secreted MbxA from Moraxella bovis induces a membrane blebbing response of the human host cell

Scientific Reports, 2022
Many proteins of the Repeats in Toxins (RTX) protein family are toxins of Gram-negative pathogens including hemolysin A (HlyA) of uropathogenic E. coli. RTX proteins are secreted via Type I secretion systems (T1SS) and adopt their native conformation in ...

Associated roles of hemolysin and p60 protein for the intracellular growth ofBacillus subtilis [PDF]

FEMS Immunology & Medical Microbiology, 2006
Hemolysin expressing Bacillus subtilis strain (B. subtilis ble/hlA) was used as a carrier for listerial protein p60 to study the impact of this protein on bacterial virulence independent of other gene products of Listeria monocytogenes. Bacillus subtilis ble/hlyA exhibited longer cell chains than B. subtilis ble/hlyA/iap.

Complex Formation between NheB and NheC Is Necessary to Induce Cytotoxic Activity by the Three-Component Bacillus cereus Nhe Enterotoxin. [PDF]

, 2013
The nonhemolytic enterotoxin (Nhe) is known as a major pathogenicity factor for the diarrheal type of food poisoning caused by Bacillus cereus. The Nhe complex consists of NheA, NheB and NheC, all of them required to reach maximum cytotoxicity following ...

TolC, an Escherichia coli outer membrane protein required for hemolysin secretion. [PDF]

Proceedings of the National Academy of Sciences, 1990
Secretion of Escherichia coli alpha-hemolysin into the medium does not require the cleavage of an N-terminal signal peptide. The specific secretion apparatus was shown to consist of two proteins, HlyB and HlyD, both located in the inner membrane and encoded by genes contiguous to the hemolysin structural gene (hlyA).

DNase and Gelatinase Activities Of β -Hemolysin Aeromonas hydrophila Isolated from Catfish (Clarias batrachus ) [PDF]

, 2021
Aeromonas hydrophila infection can cause mass mortality in fish and result in economic losses for farmers. These are bacterium that secrete substances or compounds that support its virulence by producing toxins and extracellular proteins in the form ...

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Identification and characterization of two temperature-induced surface-associated proteins of Streptococcus suis with high homologies to members of the arginine deiminase system of Streptococcus pyogenes

, 2002
The present study was performed to identify stress-induced putative virulence proteins of Streptococcus suis. For this, protein expression patterns of streptococci grown at 32, 37, and 42°C were compared by one- and two-dimensional gel electrophoresis ...

Photoactivated Signaling Networks using DNA‐Based Synthetic Organelles as Biomimetic Protocells

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Light‐triggered intercommunication between two types of organelle‐loaded liposomes lead to DNAzyme‐mediated on transcription‐guided structural reconfiguration of the organelles. ABSTRACT Membraneless organelles formed by phase‐separated nucleic acid or protein condensates play vital roles in regulating cellular functions.

Comparative proteomic analysis of Streptococcus suis biofilms and planktonic cells that identified biofilm infection-related immunogenic proteins. [PDF]

PLoS ONE, 2012
Streptococcus suis (SS) is a zoonotic pathogen that causes severe disease symptoms in pigs and humans. Biofilms of SS bind to extracellular matrix proteins in both endothelial and epithelial cells and cause persistent infections.
