Study Identifies Immune Cells Responsible for Severe Asthma
Researchers from the University of Southampton, United Kingdom and La Jolla Institute for Immunology (LJI) have identified a group of immune cells that may be responsible for severe asthma. Identified as cytotoxic CD4+ tissue-resident memory T cells, these cells congregate in the lungs and seem to have the ability to cause the harm associated with later development of asthma. Researchers say these immune cells are especially prevalent in men and note that men who are diagnosed with asthma after age 40 often have high counts of this specific T cell in their lungs, which increases their odds of developing severe…
