CD27 and ICOS as Targets of PD‐1/PD‐L1 Signaling to Regulate Resident Memory CD8+ T‐Cell‐Mediated Pulmonary Protection and Pathology

Advanced Science, EarlyView.
Here it is revealed that the costimulatory receptors CD27 and ICOS are essential for the long‐term maintenance of PD‐1high CD8+ TRM cells following influenza infection. PD‐L1 blockade enhances the proliferation and activation of these cells through Nur77 activation downstream of the CD27/ICOS signaling axis, thereby boosting host immunity against ...

OTUD6A in Airway Epithelial Cells Exacerbates Allergic Asthma by Promoting Airway Inflammation and Airway Remodeling Through Deubiquitination of hResistin/mRELMα

Advanced Science, EarlyView.
This study elucidates a novel mechanistic role of the deubiquitinase OTUD6A in asthma pathogenesis, uncovering its regulatory function in airway inflammation and airway remodeling through the stabilization of hResistin/mRELMα. This study offers a novel regulatory axis (OTUD6A‐hResistin/mRELMα) in asthma pathogenesis and OTUD6A inhibition as a potential

Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

Advanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

Prognostic Implications of Bronchoalveolar Fluid Analysis in Ventilator-Associated Pneumonia: An Observational Cohort Study

Egyptian Journal of Critical Care Medicine, 2022
Background Ventilator-associated pneumonia (VAP) is one of the most frequent infections with high mortality rates in intensive care units (ICUs) and the prediction of outcome is paramount in the decision-making process. Objective To assess the prognostic

Macrophage TRIM21 Inhibition Ameliorates Murine Acute Pancreatitis via PHB2‐Mediated Mitochondrial Stabilization

Advanced Science, EarlyView.
Macrophage‐derived TRIM21 drives the progression of AP via ubiquitin‐proteasome‐mediated degradation of PHB2, leading to impaired PHB2‐mediated mitophagy. Therefore, accumulation of cytosolic mtDNA hyperactivates the cGAS‐STING signaling axis, thereby amplifying inflammatory cascades.

Untargeted LC-MS metabolomics of bronchoalveolar lavage fluid differentiates acute respiratory distress syndrome from health.

Journal of Proteome Research, 2014
Acute respiratory distress syndrome (ARDS) remains a significant hazard to human health and is clinically challenging because there are no prognostic biomarkers and no effective pharmacotherapy.

CsdA‐LaeB Regulatory Hub Contributes to Aspergillus fumigatus Virulence via Fumiquinazoline C Biosynthesis

Advanced Science, EarlyView.
This study identifies a conserved CsdA‐LaeB hub in Aspergillus fumigatus that regulates secondary metabolite fumiquinazoline C (FqC). Disrupting this hub enhances FqC production and virulence, shedding new light on the post‐transcriptional regulatory logic linking secondary metabolism to pathogenicity and offering alternative strategies for diagnostic ...
