Study: Finding out how the body’s natural protective immune functions are affected by stroke

Study summary

We are trying to understand how our body’s natural protective immune functions  (B cells) are affected by stroke, why this happens and how this could be improved.  This may help us to prevent or reduce the risk of stroke-associated infection and improve health for people who have had a stroke.

B cells are important immune cells in our bodies that produce antibodies to help find and kill bacteria when we have an infection. If the number of B cells in our body is too low or they do not work properly, this often leads to a much greater risk of infection. Certain types of B cells are part of our natural immune system and are very important for protecting us from bacterial infections that commonly affect people after stroke. Our recent research suggests that stroke can cause a huge loss of some types of B cells.
