Cystic Fibrosis Explained | Why CFTR Channel Is So Unique? | MBBS | NEET PG | Dr Vivek Nalgirkar |

Cystic fibrosis is a genetic disorder caused by a defect in a very unusual ion channel — the CFTR channel. What makes this channel special? 👉 It is named after the disease itself 👉 It functions as a chloride (Cl⁻) channel 👉 It also regulates and inhibits other adjacent ion channels Pathophysiology of cystic fibrosis involves a channel. It is a Cl- channel. The channel is named after the disease, which is unusual. It regulates not only the flow of Cl- through it, but also regulates/inhibits flow of other ions through other adjacent channels. Watch the video to understand its pathophysiology in detail. In this concept-based video, we explain the pathophysiology of cystic fibrosis in a clear, exam-oriented manner — focusing on how CFTR dysfunction leads to thick secretions, recurrent infections, and multisystem involvement. 🧠 In this video, you will understand: • What is the CFTR channel and why it is unique • How CFTR regulates chloride movement • How it indirectly controls sodium and water transport • Why its dysfunction causes thick mucus • The integrated physiology behind cystic fibrosis 🎯 High-yield for: • 1st MBBS – Physiology • Pathophysiology concepts • NEET PG / NExT / FMGE • USMLE / PLAB basics • Channelopathies & transport mechanisms 📌 Language: English (conceptual) 📌 Topic: Physiology – Cell membrane & ion channels 👉 Watch till the end — CFTR is a favorite examiner concept and easy to score when understood properly. #cysticfibrosis #CFTR #physiology #pathophysiology #mbbs #neetpg #nextexam #fmge #usmle #medicalconcepts #channel
