- IPF development involves a two-hit process: an initial vulnerability of the lung's epithelial cells followed by a second injury that triggers fibrotic changes.
- Genetic factors play a crucial role in the first hit, while ongoing damage disrupts normal cell function and activates fibroblasts, leading to lung fibrosis.
- Understanding IPF in terms of its stages may lead to new treatments that target these underlying causes, aiming for a shift from palliative care to potential cures for patients.
