Transforming growth factor beta (TGF-β) plays a key role in severe asthma. This review explores TGF-β1 as a potential therapeutic target for personalized asthma treatments.
Area of Science:
- Immunology
- Pulmonology
- Genetics
Background:
- Asthma is a chronic airway inflammatory disease influenced by cellular interactions and mediators.
- Biomarkers for asthma symptoms and obstruction are crucial for treatment development.
- Transforming growth factor beta (TGF-β) is implicated in airway inflammation and remodeling in asthma.
Purpose of the Study:
- To review the role of TGF-β in severe asthma.
- To explore its interactions with T-helper cells, cytokines, and regulatory T-cells.
- To investigate associations with eosinophils and genetic polymorphisms of TGF-β1.
Main Methods:
- Literature review focusing on TGF-β in severe asthma.
- Analysis of TGF-β interactions with immune cells and cytokines.
- Exploration of genetic polymorphisms and clinical phenotypes.
Main Results:
- TGF-β is a significant mediator in severe asthma, influencing inflammation and fibrosis.
- Interactions with T-cells and cytokines are central to its role.
- TGF-β1 genetic variations may impact asthma susceptibility and severity.
Conclusions:
- TGF-β1 is a promising therapeutic target for severe asthma.
- Understanding TGF-β pathways can identify phenotypes for individualized therapy.
- Modulating TGF-β may offer novel treatment strategies for specific asthma patient groups.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
