What is the difference between Cystic Fibrosis and Primary Ciliary Dyskinesia? (pathophysiology)
Переглядів 2 тис.4 роки тому
The question asked was: “What is the difference between CF and PCD?” Script: PCD was once considered a milder form of CF as the two present the same. However, the pathophysiologies differ. Now in cystic fibrosis, we have a defective CFTR gene. This CFTR gene is responsible of movement of chloride ions out of the cells and inhibition of the epithelial sodium channel or ENaC. Remember wherever so...
