Long-term memory in epithelia: transient IFNγ exposure drives stable repression of TFF1 in gastric epithelial cells via epigenetic changes

Frontiers in Immunology
IntroductionInterferon-gamma (IFNγ) is a pro-inflammatory cytokine that is transiently produced and typically activates short-lived JAK–STAT1 signaling, yet it can also induce long-term transcriptional changes.

Association of Helicobacter pylori vacA polymorphisms with the risk of gastric precancerous lesions in a Moroccan population

Journal of Infection in Developing Countries, 2021
Introduction: Helicobacter pylori infection is the major risk factor of atrophic gastritis and intestinal metaplasia. The vacA gene is one of the most virulence factors of H.

Misidentifying Helicobacters: the Helicobacter cinaedi Example [PDF]

Journal of Clinical Microbiology, 2000
ABSTRACT Whole-cell protein electrophoresis and biochemical examination by means of a panel of 64 tests were used to identify 14 putative helicobacters to the species level. The results were confirmed by means of DNA-DNA hybridization experiments and were used to discuss misidentification of helicobacters based on 16S rRNA gene ...

Helicobacter salomonis sp. nov., a Canine Gastric Helicobacter sp. Related to Helicobacter felis and Helicobacter bizzozeronii [PDF]

International Journal of Systematic Bacteriology, 1997
During a study of the prevalence and distribution of gastric helicobacters in domestic pets, a novel group of Helicobacter-like organisms were identified. These "Helicobacter group 2" strains were initially distinguished from the species Helicobacter felis and Helicobacter bizzozeronii by their cellular morphology and the type of motility exhibited ...

The SlyD metallochaperone targets iron-sulfur biogenesis pathways and the TCA cycle

mBio, 2023
Control of protein folding is a conserved function in all domains of life. The ubiquitous peptidyl-prolyl cis-trans isomerases (PPIases) catalyze the cis/trans-isomerization of peptidyl-prolyl bonds, often a rate-limiting step for protein folding ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,
