Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

Structural and Biochemical Characterization of the Diaminopimelate Epimerase DapF From Pseudomonas aeruginosa PA14

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The emergence of antibiotic resistance in bacteria is a major threat to global public health. To combat increasingly drug‐resistant bacteria like Pseudomonas aeruginosa, new targets for pharmaceuticals need to be explored. One such potential target for P.

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

open access: yesAllergy, EarlyView.
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 ...

Longer Asthma Duration Is Associated With Elevated Non‐T2 Sputum Biomarkers and Reduced T2 Inflammation in Severe Asthma

open access: yesAllergy, EarlyView.
Longer asthma duration is associated with increased airway non‐T2 inflammation and reduced airway and systemic T2 inflammation. Sputum CXCL9 is independently associated with duration and may predict a reduced poor response to anti‐IL‐4Rα therapy. Airway sampling and combined T2 and non‐T2 targeted strategies may be needed in long‐standing asthma. CXCL9,

Revisiting mutational resistance to ampicillin and cefotaxime in Haemophilus influenzae

open access: yesGenome Medicine
Background Haemophilus influenzae is an opportunistic bacterial pathogen that can cause severe respiratory tract and invasive infections. The emergence of β-lactamase-negative ampicillin-resistant (BLNAR) strains and unclear correlations between ...

Simultaneous purulent pericarditis and acute epiglottitis from Haemophilus influenzae in an immunocompetent adult: a case report

open access: yesInternational Journal of Infectious Diseases
Objectives: Haemophilus influenzae can cause severe and invasive disease. While purulent pericarditis and epiglottitis are known to be rare complications of Haemophilus influenzae, we report a rare case of their simultaneous occurrence.

The Airway Transcriptome in Type 2 Cytokine Biomarker‐High and ‐Low Severe Asthma

open access: yesAllergy, EarlyView.
This study distinguishes severe asthma–related airway transcriptomic changes from the effects of high‐dose ICS. Most dysregulated genes in severe asthma show concordance with corticosteroid responses. Corticosteroid‐resistant T2‐high asthma featured T2‐high and epithelial barrier gene upregulation, while T2‐low asthma featured Th1/IL‐17 signatures. ASM,
