New clues on why pregnancy may increase risk of organ transplant rejection
Study finds that one arm of the immune system becomes tolerant to a fetus while the other becomes sensitized, providing new insights on how prior pregnancies can create challenges for transplant recipients
A research study at the University of Chicago has found that in pregnancy, while the T cell response to a fetus becomes tolerant to allow for successful pregnancy, the part of the immune system that produces antibodies (known as the humoral response) becomes sensitized, creating memory B cells that can later contribute to the rejection of a transplanted organ.
The results help to clarify why it is that the immune system can tolerate a fetus during pregnancy, but later may be more likely to become sensitized to and reject an organ transplant. The study was published on January 4, 2021 in the END
