Washington: Based on more than 50 experiments with mice, scientists have mapped out the basic steps taken by a particular set of white blood cells in setting the pace for recovery after serious lung injury.The white blood cells are called regulatory T-cells, or Tregs for short, and their best known function is to keep the body`s immune system from attacking its own healthy tissues.
Among them are people with severe acute respiratory distress syndrome caused by infection, the most severe form of ALI. Also included are burn victims, people with chest injuries from car accidents, and cancer patients who have had adverse reactions to donated platelets from blood transfusion. Almost all people with ALI require breathing assistance from mechanical ventilators, and nearly 75,000 die each year. The study was published online in the Journal of Clinical Investigation. IANS
