Abstract
Pre-existing alloreactive memory T cells are a major barrier to the induction of allograft tolerance in organ transplant recipients. The use of Eomesodermin (Eomes) expression in memory T cells to determine the risk of allograft rejection in a subject is described. Also described is the use of Eomes expression in memory T cells of transplant recipients to modify immunosuppressive therapy.
Claims20
A method of determining the risk of allograft rejection in a subject, comprising:
- isolating memory T cells from a peripheral blood mononuclear cell (PBMC) sample obtained from the subject;
- measuring expression of Eomesodermin (Eomes) in the memory T cells, wherein expression of Eomes is measured in the memory T cells after exposure of the memory T cells to donor-derived cells ex vivo;
- and
- detecting an increase in expression of Eomes in the memory T cells exposed to donor-derived cells compared to expression of Eomes in control memory T cells, thereby determining an increased risk for allograft rejection in the subject.
A method of treating a subject who is at risk of allograft rejection, comprising:
- administering an immunosuppressive therapy to the subject;
- isolating memory T cells from a peripheral blood mononuclear cell (PBMC) sample obtained from the subject;
- measuring expression of Eomesodermin (Eomes) in the memory T cells, wherein expression of Eomes is measured in the memory T cells after exposure of the memory T cells to donor-derived cells ex vivo;
- and
- detecting an increase in expression of Eomes in the memory T cells exposed to donor-derived cells compared to expression of Eomes in control memory T cells, thereby determining an increased risk for allograft rejection in the subject;
- and
- modifying the immunosuppressive therapy administered to the subject.
