How Does asthma affect the epithelial tissue?
In asthma, the bronchial epithelium is modified and appears fragile and activated. Abnormalities include the loss of the most superficial layer of the epithelium, destruction of ciliated cells, upregulation of growth-factor release, and the overexpression of receptors, such as epidermal growth factor receptors (EGFR).
What disease affects the epithelial tissue?
Epithelioid mesothelioma is a form of the asbestos cancer that develops in the epithelial cells. It is the most common type of mesothelioma, making up about 70 percent of all mesothelioma cases.
Does asthma affect cells?

What cell causes asthma?
Asthma is a chronic airway inflammatory disease characterized by the infiltration of airway T cells, CD(+) (T helper) cells, mast cells, basophils, macrophages, and eosinophils.
What are the immediate health effects of asthma?
Pneumonia: Asthma affects the airways and breathing. This can affect how long it takes for you to recover from pneumonia. This infection causes inflammation in the lungs. Symptoms include difficulty breathing, a fever, chest pain, and a rapid heartbeat.
Is asthma a lung disease?

Severe asthma is defined as someone diagnosed with asthma requiring medium or high-dose inhaled corticosteroids combined with other longer-acting medications. Asthma is also considered severe when it is uncontrolled despite proper use of these medications.
