Infection an important post-stroke problem

from e Science News

After a stroke the brain tries to protect itself by blocking all inflammation. However, this also makes the patient highly susceptible to infection, which can lead to death. Researchers have now discovered the mechanism behind this response and how to possibly treat it. The research was published in October in the journal Science. Using a mouse model, scientists at the University of Calgary's Faculty of Medicine have discovered Natural Killer T-cells are the immune cells that get activated in the patient after a stroke. The cells suppress the immune system as the body tries to prevent inflammation to protect the brain. The researchers also have found a new drug that can stop the NKT cells from suppressing the immune system, stopping the infections. more
