Overweight People More
Likely To Have Asthma - Obesity Linked to Lung Ailment - Australian
Study Found Protein That Triggers Attacks
July 14th 2006
Australian researchers at Sydney's Garvan Institute believe there is a
link between obesity and asthma and speculate that this is the reason
why asthma is on the increase in Western countries. They have found a
fatty acid binding protein called aP2 in the lungs of asthma patients.
This protein has already been known for its role in diabetes and
obesity. Now they know it is present in the lungs where it is crucial
in controlling inflammation in asthma.
There are various triggers, such as dust mites and pollen that bring on
asthma attacks. The scientists believe that high levels of aP2 in human
lung cells trick the body into thinking it is undergoing an asthma
attack. The attack is characterized by inflammation of the airways, a
tightening of the surrounding muscles, and excess mucus production.
