What do you know about CFTR
1. 2. 3. 4. 5.
It stands for cystic fibrosis transmembrane
conductance regulator
It functions as a chloride ion channel
It is localized to the plasma membrane
Cystic fibrosis is caused by a mutation in the
CFTR gene
There are over 400 different mutations known for
CFTR gene

Mucus, Mucus, Mucus
1. 2. 3. 4. 5.
Traps dust, dirt, germs in the lining of your
nose, trachea and lungs
What does mucus do?
Tiny hairs that push mucus out of your lungs and
into your throat
What are cilia?
Mucus glands
Where is mucus made?
The system of mucus and cilia that rids our lungs
of bacteria
What is the mucociliary escalator?
There are over 400 different mutations known for
CFTR gene
What is different about the mucus of people with
CF?
