What causes excess secretion of trypsin to lead to emphysema?

Excess secretion of trypsin can lead to the degradation of elastic fibers in lung tissue, contributing to the development of emphysema. Normally, trypsin is regulated by alpha-1 antitrypsin, which protects lung tissue from excessive proteolytic activity. When there is an imbalance, either due to genetic factors like alpha-1 antitrypsin deficiency or increased trypsin activity, it can result in the destruction of alveolar walls, leading to emphysema. This condition impairs lung function and reduces respiratory efficiency.
