Graduate Medical Education (GME) Resident and Fellow Research Day Posters
Introduction/Background
Hematopoietic cell transplantation (HCT) provides
a cure for patients with acute myeloid leukemia.
Natural killer cells (NK) play an important role
in graft versus leukemia (GVL) effect after HCT,
through killer immunoglobulin-like receptor (KIR)
interaction with HLA ligands. This study is
undertaken to validate our previously published
mathematical model accounting for the KIR-KIRL
interactions in a post HCT setting.
Methods
Retrospective data were obtained from the Center
for International Blood and Marrow Transplant
Registry for 2317 donor recipient pairs (DRP) who
underwent 7/8 or 8/8 HLA allelic matched
unrelated donor (URD) HCT for AML. KIR-HLA
interaction scores were calculated …

Myeloid Derived Suppressor Cells (MDSC) represent a significant hurdle to cancer immunotherapy because they dampen anti-tumor cytotoxic T cell responses. Previous studies have reported on the myelo-depletive effects of certain chemotherapies. Using guadecitabine, a next-generation DNA methyltransferase inhibitor (DNMTi), we observed significantly reduced tumor burden in the 4T1 murine mammary carcinoma model. Guadecitabine treatment prevents excessive tumor-induced myeloid proliferation and systemic accumulation, and skews remaining MDSCs toward a beneficial antigen-presenting phenotype. Together, this alters the splenic environment to improve T cell activation and interferon-gamma (IFNg) production. Additionally, guadecitabine enhances the therapeutic effect of adoptively transferred antigen-experienced lymphocytes to diminish tumor …

Cell mass is an important indicator of cell health and status. A diverse set of techniques have been developed to precisely measure the masses of single cells, with varying degrees of technical complexity and throughput. Here, the development of a non-invasive, label-free optical technique, termed Live-Cell Interferometry (LCI), is described. Several applications are presented, including an evaluation of LCI’s utility for assessing drug response heterogeneity in patient-derived melanoma lines and the measurement of CD3+ T cell kinetics during hematopoietic stem cell transplantation. The characterization of mast cells during degranulation, the measurement of viral reactivation kinetics in Kaposi’s Sarcoma, and drug …
