Immune cells may hold key to controlling asthma and allergies

Researchers found that a protein released by mast cells — key players in allergic reactions — actually dampens airway muscle contractions in human lung tissue. The discovery could redirect drug development away from simply blocking mast cells toward harnessing their natural regulatory mechanisms, potentially opening new treatment pathways for asthma and chronic respiratory conditions.
