Polyphenol‐Based Biomaterials for Antibacterial Infection Management: From Assembly Chemistry to Infection Site‐Specific Therapeutic Platforms

open access: yescMat, Volume 3, Issue 3, September 2026.
Polyphenol assembly chemistry provides a versatile basis for antibacterial biomaterials. Matching material format and function to the distinct barriers of wound, respiratory, intestinal, and implant‐associated infections is central to effective and translatable design. ABSTRACT Bacterial infections involving multidrug‐resistant pathogens and persistent

3D Reconstruction of the Human Airway Mucosa In Vitro as an Experimental Model to Study NTHi Infections

open access: yesPLoS ONE, 2016
We have established an in vitro 3D system which recapitulates the human tracheo-bronchial mucosa comprehensive of the pseudostratified epithelium and the underlying stromal tissue. In particular, we reported that the mature model, entirely constituted of

Resolving Endoplasmic Reticulum‐Protein Misfolding Restores Corticosteroid Sensitivity in Experimental Models of Severe Asthma

open access: yesAllergy, Volume 81, Issue 9, Page 3221-3235, September 2026.
This study investigates the role of ER stress in steroid resistance in severe asthma. Results from advanced 3D models of human bronchial epithelial cells, steroid‐resistant severe asthma mouse models, and human severe asthma sputum samples show that treatment with ICS in combination with the ER stress inhibitor 4‐PBA significantly enhances steroid ...

NTHi-IAV coinfection of macrophages alters infection outcomes and inflammatory responses

open access: yes, 2022
Nontypeable Haemophilus influenzae (NTHi) chronically colonises the airway of individuals with chronic respiratory disease, with persistence suggested to be facilitated by invasion of airway macrophages. Previous data supports an interaction between NTHi

Curcumin suppresses NTHi-induced CXCL5 expression via inhibition of positive IKKβ pathway and up-regulation of negative MKP-1 pathway

open access: yesScientific Reports, 2016
Otitis media (OM) is the most common childhood bacterial infection and leading cause of conductive hearing loss. Nontypeable Haemophilus influenzae (NTHi) is a major bacterial pathogen for OM.

On the Alternative Protonation of Heterocyclic Michler´s Ketone Analogues

open access: yesChemistrySelect, Volume 11, Issue 32, 24 August 2026.
Bis(5‐aminothionyl)ketones exhibit a significant bathochromic shift in the UV–vis absorption spectrum and form deeply violet proton adducts under acidic conditions. NMR spectroscopy and quantum chemical calculations confirm that O‐protonation occurs. In contrast, protonation of the amino groups in Michler´s ketone and the heterocyclic aza moieties in ...

Human neutrophil elastase degrades SPLUNC1 and impairs airway epithelial defense against bacteria. [PDF]

open access: yesPLoS ONE, 2013
Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are a significant cause of mortality of COPD patients, and pose a huge burden on healthcare. One of the major causes of AECOPD is airway bacterial (e.g.

Research on the Mechanism of Natural Products Acting on Chronic Obstructive Pulmonary Disease

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
This figure illustrates that approximately 80 natural compounds exert therapeutic effects against chronic obstructive pulmonary disease by targeting pathological mechanisms such as airway inflammation, oxidative stress, airway remodeling, mucus hypersecretion, emphysema, protease–antiprotease imbalance, apoptosis, and autophagy.

Distribution of sequenced NTHi isolates.

open access: yes, 2015
Neighbor joining dendogram of NTHi strains used in this study. The tree is rooted with Eschericia coli MG1655 and is based on sequence comparisons of the concatenated adk, pgi, recA, infB and 16s rRNA gene sequences, with bootstrap values of greater than
