The major drawbacks regarding TKIs are their low efficacy in eradicating the leukemic stem cells responsible for disease maintenance and relapse upon drug cessation. Herein, we performed ribonucleic acid sequencing of flow-sorted primitive (CD34<sup>+</sup>CD38<sup>low</sup>) and progenitor (CD34<sup>+</sup> CD38<sup>+</sup&gt;) chronic phase CML cells, and identified transcriptional upregulation of 32 cell surface molecules relative to corresponding normal bone marrow cells. Focusing on novel markers with increased expression on primitive CML cells, we confirmed upregulation of the scavenger receptor CD36 and the leptin receptor by flow cytometry. We also delineate a subpopulation of primitive CML cells expressing CD36 that is less sensitive to imatinib treatment. Using CD36 targeting antibodies, we show that the CD36 positive cells can be targeted and killed by antibody-dependent cellular cytotoxicity. In summary, CD36 defines a subpopulation of primitive CML cells with decreased imatinib sensitivity that can be effectively targeted and killed using an anti-CD36 antibody.}, number={3}, journal={Haematologica}, author={Niklas Landberg and Sofia von Palffy and Maria Askmyr and Henrik Lilljebjörn and Carl Sandén and Marianne Rissler and Satu Mustjoki and Henrik Hjorth-Hansen and Johan Richter and Helena Ågerstam and Marcus Järås and Thoas Fioretos}, year={2018}, month={Feb.}, pages={447-455} }
