This study aims to assess mast cell infiltration in airway smooth muscle of individuals with asthma compared to healthy controls.
Used design-based stereology to quantify mast cells in airway compartments.
Analyzed biopsy samples from 32 individuals: 8 healthy controls and 24 with asthma (14 EIB+ and 10 EIB-).
Evaluated mast cell density, ASM volume, and correlation with airway functions and inflammatory markers.
No significant differences in mast cell density in airway smooth muscle between asthma and control groups.
Airway hyperresponsiveness was not linked to differences in mast cell density.
Higher intra-epithelial mast cell density found in individuals with asthma, particularly in those with exercise-induced bronchoconstriction.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Randomized trial demonstrates no differences in mast cell density in airway smooth muscle in asthma, suggesting a lack of association with airway hyperresponsiveness.
