Why does a1 antitrypsin destroy lungs?
Alpha-1 antitrypsin deficiency (AATD) is an inherited disorder characterized by low serum levels of alpha-1 antitrypsin (AAT). Loss of AAT disrupts the protease-antiprotease balance in the lungs, allowing proteases, specifically neutrophil elastase, to act uninhibited and destroy lung matrix and alveolar structures.

How does alpha 1 affect the lungs?
If you have alpha-1, you don't have enough of a protein that normally protects the lungs from damage. Augmentation therapy raises your levels of that protein. You get it through an IV tube into a vein in your arm. The extra alpha-1 moves through your blood to your lungs and may slow down the damage.

What is the alpha 1 gene?
Alpha-1 antitrypsin deficiency (AATD) is inherited in families in an autosomal co dominant pattern. Codominant inheritance means that two different variants of the gene (alleles) may be expressed, and both versions contribute to the genetic trait.

What is codominant inheritance?
Codominant inheritance means that two different variants of the gene (alleles) may be expressed, and both versions contribute to the genetic trait. The M gene is the most common allele of the alpha-1 gene. It produces normal levels of the alpha-1 antitrypsin protein. The Z gene is the most common variant of the gene.
What is the S allele?
The S allele is another, less common variant that causes ATTD. If a person inherits one M gene and one Z gene or one S gene ('type PiMZ' or 'type PiMS'), that person is a carrier of the disorder. While such a person may not have normal levels of alpha-1 antitrypsin, there should be enough to protect the lungs.

What is the name of the disease that affects the alveoli?
Emphysema is a disease of the alveoli (the tiny air sacs in the lungs). Chronic bronchitis is a disease of the bronchus (the tubes through which air passes in the lungs). The trachea can also be involved. During inhalation, air travels through the nose and/or mouth into the trachea (windpipe).
What are the two tubes that separate the trachea?
The trachea further divides into two tubes called bronchi. The bronchi branch out into smaller tubes called bronchioles. The ends of bronchioles open into little air sacs called alveoli, which aid in gaseous exchange.
