I’m Gabe Garza with today’s health news. If you’ve ever had an asthma attack, you
know how terrifying it can be. Some asthmatics compare those attacks to trying
to breathe through a straw. What if asthma attacks could simply be switched
off? According to a press release issued by Johns
Hopkins Medicine, researchers at the university have discovered a cellular “off” switch
for the inflammatory immune response that triggers lung-constricting asthma attacks. The switch is composed of regulatory proteins
that control an immune signaling pathway in cells. Previous research linked asthma to one type
of immune cell called M2 macrophages in the lungs. In non-asthmatic people, M2 activates to clean
up allergens and foreign particles. In asthmatics, M2 cells’ chemical signal
lingers and calls in other cells that cause inflammation. Researchers found two different types of proteins
that when decreased, signal M2 production and turn it on. Researchers went on to say that they hope
this research will have applications for cancer and obesity treatment as well. For dailyRx, I’m Gabe Garza.
