Immune Cells Offer Hope for Injured Lungs
MONDAY, Sept. 21 (HealthDay News) -- New research in mice is shedding light on how a special group of immune cells heal badly injured lungs. The next step is to find a way to boost the cells in patients or get them to work harder when needed, researchers say.
"Our study results are the critical first leads in finding treatments for a clinical condition that until now has had none, despite its high mortality," study senior investigator Dr. Landon King, director of pulmonary and critical care medicine at the Johns Hopkins University School of Medicine in Baltimore, said in a news release. "When a patient develops acute lung injury, we want the critical care medicine team to be able to do more than just stabilize the patient on a ventilator."
An estimated 200,000 Americans suffer from sudden acute lung injury each year. The causes include burns, car accidents that injure the chest, and cancer. About 75,000 of those injured die each year.
The injuries cause cells in the lungs to try to defend themselves by creating inflammation. But inflammation is a double-edged sword that can make it difficult to breathe.
