Unraveling Mechanisms of Persister Formation during Normal Growth

open access: yes, 2015
Persisters are phenotypic variants present within bacterial populations that exhibit extreme tolerance toward antibiotic stress and are believed to be responsible for chronic and recurrent infections.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

open access: yesFEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Controlling Bacterial Persister Cells and Biofilms by Synthetic Brominated Furanones

open access: yes, 2013
Bacteria are well known to obtain tolerance to antibiotics by forming multicellular structures, known as biofilms, and by entering dormancy and forming persister cells.

Immune system detection of Pseudomonas aeruginosa persister cells

open access: yes, 2020
Persister cells are a subpopulation of bacterial cells known to be tolerant to antimicrobials. Their reduced susceptibility to antimicrobials allows them to be the source of recurrence of many chronic bacterial infections.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Persister cell-mediated antimicrobial tolerance in pseudomonas aeruginosa biofilm populations

open access: yes, 2011
Bacteria preferentially live in biofilms; complex structures of single- or multiple- species of bacteria, surrounded by a self-produced polymeric extracellular matrix and attached to a surface.

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Persister Cell Control Mechanisms in Uropathogenic Escherichia coli

open access: yes, 2015
Persister cells are a subpopulation of bacteria that demonstrate high tolerance to antibiotics, but revert to sensitivity after antibiotics are removed.

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.
