New knowledge from the team from Emory University is that our bodies have a type of cell that have a label on them, CD122, that are found in hearts undergoing rejection. Over the next 2 years, this team will use an experimental model of rejection following heart transplantation to determine if increased numbers of CD122 cells can be detected in rejecting hearts from outside the body. The same tool used to detect CD122, an antibody, will also be tested to see if giving that antibody will prevent later rejection. We will learn in two years how this works in practice and share that with you.
