Synthesized Geopolymers Adsorb Bacterial Proteins, Toxins, and Cells

Frontiers in Bioengineering and Biotechnology, 2020
Pore-forming and hemolytic toxins are bacterial cytotoxic proteins required for virulence in many pathogens, including staphylococci and streptococci, and are notably associated with clinical manifestations of disease.

Leptospiral TlyC is an extracellular matrix‐binding protein and does not present hemolysin activity [PDF]

FEBS Letters, 2009
The role of TlyA, TlyB and TlyC proteins in the biology of Leptospira is still uncertain. Although these proteins have been considered as putative hemolysins, we demonstrate that leptospiral recombinant TlyB and TlyC do not possess hemolytic activity.

Pore-Forming Toxin-Like Proteins in the Anti-Parasitoid Immune Response of Drosophila

Journal of Innate Immunity
Introduction: Species of the ananassae subgroup of Drosophilidae are highly resistant to parasitoid wasp infections. We have previously shown that the genes encoding cytolethal distending toxin B (CdtB) and the apoptosis inducing protein of 56

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 ...

Determination of the antibacterial effect of bee venom against rainbow trout pathogens and antibiotic resistance gene expression

Acta Veterinaria, 2023
Bee venom (BV) is a rich source of secondary metabolites from honeybees (Apis mellifera L.). It contains a variety of bioactive ingredients including peptides, proteins, enzymes, and volatile metabolites. This study investigated the antibacterial effects

Directionality of substrate translocation of the hemolysin A Type I secretion system

Scientific Reports, 2015
Type 1 secretion systems (T1SS) of Gram-negative bacteria are responsible for the secretion of various proteases, lipases, S-layer proteins or toxins into the extracellular space.

Roles of Hcp family proteins in the pathogenesis of the porcine extraintestinal pathogenic Escherichia coli type VI secretion system

Scientific Reports, 2016
Hcp (hemolysin-coregulated protein) is considered a vital component of the functional T6SS (Type VI Secretion System), which is a newly discovered secretion system.
