Heat‐Not‐Burn Tobacco Aerosols Induce Immune Dysregulation and Barrier Disruption Comparable to Conventional Cigarettes

Allergy, Volume 81, Issue 3, Page 781-795, March 2026.
Comparative analysis between cigarette smokers and HnB users revealed similar inflammatory lung function parameters and immunophenotypic patterns. Cigarette smoke and HnB aerosol had an impact on ECM through divergent downstream pathways. Exposed to Cigarette smoke and HnB aerosol caused comparative TJ weakening in the epithelial barrier.
