Alvarez R, Neumann G, Fravega J, Diaz F, Tejias C, Collao B, et al.
Biochem Biophys Res Commun
. 2015 Feb;
458(1):46-51.
PMID: 25637663
It has been proposed that some antibiotics exert additional damage through reactive oxygen species (ROS) production. Since H₂S protects neurons and cardiac muscle from oxidative stress, it has been hypothesized...

Aguayo D, Pacheco N, Morales E, Collao B, Luraschi R, Cabezas C, et al.
Arch Biochem Biophys
. 2015 Jan;
568:38-45.
PMID: 25600570
OmpD is the major Salmonella enterica serovar Typhimurium (S. Typhimurium) porin and mediates hydrogen peroxide (H2O2) influx. The results described herein extend this finding to hypochlorous acid (HOCl), another reactive...

PMID: 25496196
Background: Most semiconductor nanoparticles used in biomedical applications are made of heavy metals and involve synthetic methods that require organic solvents and high temperatures. This issue makes the development of...

Ipinza F, Collao B, Monsalva D, Bustamante V, Luraschi R, Alegria-Arcos M, et al.
PLoS One
. 2014 Nov;
9(10):e111062.
PMID: 25360745
Salmonella Typhimurium is the etiological agent of gastroenteritis in humans and enteric fever in mice. Inside these hosts, Salmonella must overcome hostile conditions to develop a successful infection, a process...

Calderon I, Morales E, Collao B, Calderon P, Chahuan C, Acuna L, et al.
Res Microbiol
. 2013 Nov;
165(1):30-40.
PMID: 24239962
As part of the response to specific stress conditions, bacteria express small molecules of non-coding RNA which maintain cellular homeostasis by regulating gene expression, commonly at the post-transcriptional level. Among...

PMID: 24044554
Background: Hydrogen peroxide (H₂O₂) is a reactive oxygen species (ROS), which is part of the oxidative burst encountered upon internalization of Salmonella enterica serovar Typhimurium (S. Typhimurium) by phagocytic cells....

Res Microbiol
. 2010 Dec;
162(2):214-22.
PMID: 21144897
Here we demonstrate that OmpD, the most abundant porin in Salmonella enterica serovar Typhimurium, facilitates uptake of hydrogen peroxide (H₂O₂) and that its expression is negatively regulated by ArcA upon...
