Common respiratory virus manipulates immune genes to protect itself
12 Oct 2021 at 8:22am
Researchers have discovered that the viral protein NS1 from respiratory syncytial virus (RSV) alters the activity of immune genes, sabotaging the immune response to RSV infection.

New study reveals lung cell roles in pulmonary immunity
5 Oct 2021 at 7:18am
Researchers have found that control of immunity in the lungs is accomplished by cells that line the air spaces, epithelial cells, using a specialized immune-facing molecule, MHC-II. This epithelial MHC-II is essential for localizing and scripting highly specialized immune cells called resident memory T (TRM) lymphocytes inside the lungs.

When the western US burns, the east also gets sick
4 Oct 2021 at 8:51am
While most of the largest U.S. wildfires occur in the Western U.S., almost three-quarters of the smoke-related deaths and visits to the emergency room for asthma occur east of the Rocky Mountains. A new study finds that smoke contributes to a larger percentage of health problems in the West, but affects greater numbers of people in the East.

Allergic stimulation activates mast cell precursor cells
30 Sep 2021 at 11:07am
Mast cell precursor cells do not just cause an increase in mature mast cells during inflammation, they also play an active role in diseases like asthma, according to a new study.

Little research available on the long-term effects of tear gas use
20 Sep 2021 at 8:13am
Researchers say more rigorous research is needed to determine the long-term level of safety of tear gas exposure.

Allergies to mRNA-based COVID-19 vaccines rare, generally mild, study finds
17 Sep 2021 at 1:12pm
Allergic reactions to the new mRNA-based COVID-19 vaccines are rare, typically mild and treatable, and they should not deter people from becoming vaccinated, according to researchers.

Firefighter exposure to wildfire smoke compounds varies, depending on duties
8 Sep 2021 at 3:06pm
Every summer, wildfires rage across the western U.S., and wildland firefighters are tasked with putting them out. But in the process, they inhale smoke and all the compounds in it, which can be harmful at high amounts. Now, researchers have evaluated the presence of particulate matter and volatile organic compounds (VOCs) around firefighters actively combating blazes, finding the highest exposures among hotshot crews and those creating firebreaks.

Study explores why asthma worsens at night
6 Sep 2021 at 12:14pm
For hundreds of years, people have observed that asthma severity often worsens in the nighttime. One longstanding question has been to what degree the body's internal circadian clock -- as opposed to behaviors, such as sleep and physical activities -- contributes to worsening of asthma severity.

Decades after toxic exposure, 9/11 first responders may still lower their ris...
2 Sep 2021 at 7:11am
A new study shows that losing weight and treating excess levels of fat in the blood may help prevent lung disease in those exposed to dangerous levels of fine particles from fire, smoke and toxic chemicals.

Why do short-lived lung infections lead to long-lasting lung damage?
25 Aug 2021 at 7:14am
Researchers have found that two populations of stem cells in the lung multiply during and after a viral respiratory infection, sometimes triggering a detrimental remodeling process that can cause persistent lung disease long after the virus has been cleared.

Tiny bubbles: Treating asthma with gene silencing nanocapsules
11 Aug 2021 at 10:14am
Researchers are developing novel asthma therapeutics using gene-silencing nanocapsules in a bid to help patients who aren't benefiting from existing treatments.

Computational evaluation of drug delivery reveals room for inhalers improvement
10 Aug 2021 at 8:09am
Increased air pollution in recent years has exacerbated health risks for people who suffer from pulmonary diseases and these dynamics underscore the importance of increasing the efficacy of drug delivery devices that administer active pharmaceutical ingredients to treat respiratory illnesses. Researchers describe developing a computational evaluation of drug delivery through both pressurized metered-dose inhalers and dry powder inhalers to determine how the process can be improved.

Second-hand marijuana smoke exposure associated with respiratory infections i...
29 Jul 2021 at 9:22am
Children whose parents regularly smoke or vape marijuana may experience viral respiratory infections, such as the common cold, more frequently than those whose parents do not smoke, according to a new study.

Antibiotic prescriptions for kids plummet during pandemic
20 Jul 2021 at 8:43am
A new study finds that medications prescribed for children dropped by more than a quarter during the first eight months of the pandemic compared to the previous year, with the steepest declines in infection-related medicines like antibiotics and cough-and-cold drugs.

High respiratory efforts in COVID-19 patients could result in self-inflicted ...
19 Jul 2021 at 8:05am
Some COVID-19 patients who experience acute respiratory failure respond by significantly increasing their respiratory effort -- breathing faster and more deeply. There is concern among some doctors that this level of respiratory effort can lead to further damage to these patients' lungs. Working with intensive care clinicians, engineering researchers have used computational modeling to provide new evidence that high respiratory efforts in COVID-19 patients can produce pressures and strains inside the lung that can result in injury.
