ScienceDaily (2010-06-01) -- Researchers for the first time have determined that bone marrow cells play a critical role in fighting respiratory viruses, making the bone marrow a potential therapeutic target, especially in people with compromised immune systems. They have found that during infections of the respiratory tract, cells produced by the bone marrow are instructed by proteins to migrate to the lungs to help fight infection.
Bone marrow is the soft fatty substance inside human or animal bones.
