While many patients achieve remission following induction of chemotherapy, the cancer eventually returns in 40% with increased resistance to cancer drugs. Due to high rates of relapse and drug resistance, the 5-year survival remains less than 25%. Despite mounting evidence implicating EVs in bone marrow dysfunction, more research is needed to fully map the directional transfer of AML-EVs to recipient cells, and determine how their respective cargos enforce pro-leukemic alterations to the bone marrow and extramedullary tissues. In this thesis, I investigate the fate and function of AML-EV in altering the leukemic microenvironment through direct interactions with HSPCs, supportive stroma and cytotoxic T-lymphocytes. 000008487 542__ $$fIn copyright - single owner 000008487 650__ $$aBone Marrow$$015725 000008487 650__ $$aExtracellular Vesicles$$011111 000008487 650__ $$aExosomes$$038258 000008487 6531_ $$aacute myeloid leukemia 000008487 6531_ $$aimmunosuppression 000008487 691__ $$aSchool of Medicine$$041369 000008487 692__ $$aDepartment of Biomedical Engineering$$041397 000008487 7001_ $$aButler, John T. 000008487 8564_ $$9801c8796-2127-4f44-8260-2577c124b634$$s21701714$$uhttps://digitalcollections.ohsu.edu/record/8487/files/Butler.John.2020.pdf 000008487 905__ $$a/rest/prod/ht/24/wk/05/ht24wk059 000008487 909CO $$ooai:digitalcollections.ohsu.edu:8487$$pstudent-work 000008487 980__ $$aTheses and Dissertations
