Cellular force that drives allergy, asthma can be blocked by interferon, immunologists find

A mechanism that could underlie the development of cells that drive asthma and allergies has been uncovered by immunology researchers. Asthma and allergies are both driven by an inappropriate activation of the immune system, primarily a subtype of white blood cells known as T helper 2 cells, or Th2 cells. These cells are normally responsible for defense against parasites, but are also the main culprits behind the symptoms of asthma and allergies.
