Cellular senescence, the aging of cells, plays a key role in asthma development and progression. Targeting senescent cells with senolytics and senomorphics offers promising new asthma treatment strategies.
Area of Science:
- Pulmonology
- Cellular Biology
- Gerontology
Background:
- Asthma affects 10% of the global population as a chronic respiratory disease.
- Cellular senescence, a normal process, can trigger disease when cells accumulate.
- Recent research highlights cellular senescence's significance in asthma.
Purpose of the Study:
- To review the role of cellular senescence and stress responses in asthma.
- To explore the link between asthma triggers and cellular senescence.
- To examine senolytics and senomorphics as potential asthma therapies.
Main Methods:
- Literature review focusing on cellular senescence and asthma.
- Analysis of cellular stress responses (telomere shortening, DNA damage, oxidative stress).
- Examination of the senescence-associated secretory phenotype (SASP).
Main Results:
- Cellular senescence is linked to asthma phenotypes, airway inflammation, and remodeling.
- Asthma triggers can induce cellular senescence through various stress pathways.
- Senolytics and senomorphics show potential for asthma treatment.
Conclusions:
- Cellular senescence is a potential mechanism underlying asthma.
- Targeting senescence-related molecules and pathways may offer therapeutic benefits for asthma.

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.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
