Overview
The exact pathogenesis of [disease name] is not fully understood.
OR
It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
OR
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
OR
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
OR
The progression to [disease name] usually involves the [molecular pathway].
OR
The pathophysiology of [disease/malignancy] depends on the histological subtype.
Pathophysiology
Pathogenesis
- The pathophysiology of pneumothorax depends on the underlying disease causing it.
Primary spontaneous pneumothorax
- The most common underlying pathology of primary sponataneous pneumothorax is an apical subpleural bleb (small air-filled lesions under the pleural surface).[1]
Genetics
Genetic assocaiation
The genetic association of primary sponatneous pneumothorax is as follows:[2][3][4][5][6][7]
- Primary spontaneous pneumothorax can result as a mutation in the FLCN (folliculin) gene.
- This gene codes for a protein called folliculin.
- It is produced by the cells lining the alveoli of the lung.
- Folliculin is found in the connective tissue cells that allow the lungs to contract and expand while breathing.
- It plays a role in repairing the lung tissue after damage.
- Nonsense mutation in the folliculin gene results in isolated familial sponataneous primary pneumothorax.[8]
- Altered folliculin protein can trigger the inflammatory process within the lung tissue that can alter and damage the tissue, resulting in blebs formation.
