Summary
Transforming growth factor beta 1 (TGF-β1) contributes to airway remodeling and cell shortening in asthma. Further research is needed to clarify its role in airway hyperresponsiveness and its potential as a therapeutic target.
Area of Science:
- Pulmonary Medicine
- Cell Biology
- Immunology
Background:
- Asthma pathogenesis involves airway inflammation, hyperresponsiveness, and remodeling.
- Airway structural cells play a key role in all three aspects of asthma.
- The precise relationship between airway remodeling and bronchomotor tone is not fully understood.
Purpose of the Study:
- To review the literature on the role of transforming growth factor beta 1 (TGF-β1) in airway remodeling and cell shortening.
- To elucidate the function of TGF-β1 in asthma pathogenesis.
- To investigate the link between airway remodeling and hyperresponsiveness in asthma and identify TGF-β1 as a potential therapeutic target.
Main Methods:
- Literature review of studies on TGF-β1 in asthma.
- Analysis of the role of TGF-β1 in airway structural cell function.
- Examination of the relationship between TGF-β1, airway remodeling, and hyperresponsiveness.
Main Results:
- TGF-β1 is elevated in asthmatic airways and contributes to airway remodeling and structural cell shortening.
- The specific role of TGF-β1 in mediating airway hyperresponsiveness requires further investigation.
- Evidence suggests TGF-β1 influences airway structural cell contractility.
Conclusions:
- TGF-β1 is implicated in airway remodeling and structural cell changes in asthma.
- Clarifying TGF-β1's role in airway hyperresponsiveness is crucial.
- Targeting TGF-β1 may offer a novel therapeutic strategy for asthma management.

10.8K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

4.7K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:20Asthma: Pathogenesis and Management
1.5K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
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.

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce...
