Clinical Interests
Thymic transplantation for DiGeorge syndrome, inherited immunodeficiency states

Research Interests
Dr. Markert is currently investigating thymus transplantation in complete DiGeorge syndrome.  Complete DiGeorge syndrome is a fatal genetic disorder in which patients have heart defects, severe parathyroid hypoplasia and absence of the thymus. In a research protocol complete DiGeorge patients who have no T cells are transplanted with postnatal cultured human thymic epithelial tissue.  The transplants are later biopsied to evaluate whether host stem cells have migrated to the tranplanted tissue and developed into T cells.  Sixty one infants with complete DiGeorge anomaly have been transplanted and 43 survive (70%).  Her research to date has shown that the patient can develop new host T cells in the graft and normal T cell proliferative responses to mitogens and antigens.  Thus, in infants born with no T cells because of DiGeorge syndrome, cultured donor postnatal thymic tissue is sufficient for the development of host T cells from host stem cells.  Dr. Markert is now studying patients previously transplanted to learn how long the thymus functions and why the T cell numbers in her post thymus transplantation patients remain low for age - similar to the T cell numbers in patients with partial DiGeorge anomaly who do not need thymus transplantation.
