New Study Reveals Mechanism by Which HIV Virus Destroys Lung Tissue stat : cornell

Now, new research from Weill Cornell Medicine investigators has uncovered a mechanism that might explain why this lung damage occurs. Rather than entering and reproducing in the basal cells, the virus instead bonded to the basal cells' surface and reprogrammed them to start producing an enzyme, or protease, which can break down proteins and destroy tissues, called metalloprotease-9. In the study, published May 9 in Cell Reports, investigators show how the human immunodeficiency virus, or HIV, binds to stem cells, called basal cells, which transform into other types of cells that line the airways. This process reprograms the basal cells, causing them to release enzymes, known as proteases, which can destroy lung tissue and poke holes in walls of the air sacs, where oxygen is exchanged. Up to 30 percent of HIV patients who are appropriately treated with antiretroviral therapies develop the chronic lung disease emphysema in their lifetime.




I love writing."They're now working on a full-length film, "In Between Friends," which will also focus on HIV awareness. NEW YORK (1010 WINS) — In this episode of CityViews, Sharon Barnes-Waters sits down with filmmaker Luc Stephen to discuss his short film, "CIRCLES."Stephen, a Queens resident, says the 20-minute film is meant to raise awareness about HIV/AIDS. "CIRCLES' is a story about a counselor who teaches groups about HIV. But when it comes to herself, she doesn't follow her teaching," he says. "CIRCLES" is set to be released this summer.


DOH-Broward is partnering with registered HIV testing sites, the Broward County Ryan White Part A office, Ryan White HIV primary care providers, hospitals and private physicians to implement Test and Treat. People diagnosed with HIV can ask about Test and Treat when they receive their positive test result. Here's how it helps:When HIV virus in the blood is reduced to undetectable levels, people are far less likely to develop complications, or AIDS.
