UrduLA JOLLA, CA—Scientists from La Jolla Institute for Immunology (LJI) and The University of Southampton, UK, have uncovered a group of immune cells that may drive severe asthma. These cells, called cytotoxic CD4+ tissue-resident memory T cells, gather in the lungs and appear to possess the molecular weaponry to cause the most harm in men who developed asthma later in life.

Vaping CBD Causes More Severe Lung Damage Than Vaping Nicotine, Roswell Park Study Shows
Vaping cannabidiol (CBD), a compound found in marijuana, leads to more severe lung damage than vaping nicotine, according to a study out of Roswell Park Comprehensive Cancer Center. Until now, research on the health effects of vaping, or using e-cigarettes, has focused almost exclusively on vaping nicotine as opposed to CBD. Previous research has documented the effects of smoking cannabis, but the effects of vaping cannabinoids such as CBD were not previously known.
Blocking enzyme could hold the key to preventing, treating severe COVID-19
Blocking an immune response-related enzyme holds promise in preventing or treating severe COVID-19 symptoms by reducing inflammation, tissue injury and blood clots in the lungs, new research in mice suggests.

E-cigs Can Trigger Same Lung Changes Seen in Smokers, Emphysema
UNC scientists found that the lungs of vapers – like the lungs of smokers – have elevated levels of protease enzymes, a condition known to cause emphysema in smokers. The researchers also found that the nicotine in vaping liquids is responsible for the increase in protease enzymes.
