PMA synergistically enhances NTHi-induced MUC5AC expression via MKK3/6-p38 MAPK pathway. [PDF]

open access: yes, 2013
(A) PMA synergistically enhanced NTHi-induced phosphorylation of p38 MAPK and MKK3/6, but not ERK and MEK1. (B) The synergistic induction of MUC5AC transcription by NTHi and PMA was inhibited by overexpressing DN mutant forms of p38α and p38β in human ...

Cross-talk between PKA-Cβ and p65 mediates synergistic induction of PDE4B by roflumilast and NTHi [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
SignificanceChronic obstructive pulmonary disease (COPD) is the fourth-leading cause of death worldwide. Roflumilast has been approved for COPD. However, its efficacy has been hampered by the development of tolerance, and the underlying mechanism remains unknown but may be attributed to phosphodiesterase (PDE) 4B up-regulation.

Modified Lipooligosaccharide Structure Protects Nontypeable Haemophilus influenzae from IgM-Mediated Complement Killing in Experimental Otitis Media

open access: yesmBio, 2012
Nontypeable Haemophilus influenzae (NTHi) is a Gram-negative, human-restricted pathogen. Although this bacterium typically colonizes the nasopharynx in the absence of clinical symptoms, it is also one of the major pathogens causing otitis media (OM) 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.

In Silico Modeling of Biofilm Formation by Nontypeable Haemophilus influenzae In Vivo

open access: yesmSphere, 2019
Biofilms formed by nontypeable Haemophilus influenzae (NTHI) bacteria play an important role in multiple respiratory tract diseases. Visual inspection of the morphology of biofilms formed during chronic infections shows distinct differences from biofilms

Incidence of Cefotaxime‐Resistant Haemophilus influenzae Is Linked to Regional Consumption of Oral Aminopenicillins and Parenteral Third‐Generation Cephalosporins in Norway

open access: yesAPMIS, Volume 134, Issue 4, April 2026.
ABSTRACT The emergence of cefotaxime‐resistant Haemophilus influenzae (CRHI) in Norway during the 2000s coincided with increased use of oral aminopenicillins and parenteral third‐generation cephalosporins. This study examined associations between beta‐lactam consumption and CRHI incidence. Surveillance data on antibiotic usage across Norwegian regions (

A detailed analysis of possible efficacy signals of NTHi-Mcat vaccine against severe COPD exacerbations in a previously reported randomised phase 2b trial [PDF]

open access: yes, 2022
Background: An investigational vaccine containing non-typeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis (Mcat) surface proteins did not show vaccine efficacy (VE) against combined moderate and severe (moderate/severe) exacerbations in a ...

PI3K/Akt mediates EGFR-dependent inflammation induced by NTHi in middle ear epithelial cells. [PDF]

open access: yes, 2013
(A) Cells were incubated with NTHi with or without wortmannin, and NTHi-induced NF-κB activation was measured by performing luciferase assay. (B) Cells were incubated with NTHi with or without wortmannin, and whole cell protein was collected and blotted ...
