There are numerous factors that regulate the differentiation of bone marrow hematopoietic stem and progenitor cells, which give rise to a variety of immune cells. Defects in such factors underlie many debilitating growth defects and fatal human diseases, including blood cancers, chronic infections and autoimmune syndromes. Given that proteins are the major regulators of cellular function, we have taken a proteome-centric approach to understand blood cell development and homeostasis. Our overarching goal is to understand how proteome homeostasis (“proteostasis”) and proteostasis regulators are integrated into the transcriptional and epigenetic programs that enable immune cell differentiation and function. We anticipate that these studies will yield novel understanding of immune cell biology and uncover proteostasis vulnerabilities that can be targeted to treat blood cell diseases.

Control of normal and malignant hematopoiesis by proteostasis regulators

Hematopoietic stem and progenitor cells (HSPC) are highly sensitive to proteome perturbations. Yet very little is known about how HSPC fate is influenced by key regulators of proteostasis, which include organelle unfolded/misfolded protein response pathways, the ubiquitin proteasome system and the autophagy machinery. Using animal models, studies in my lab focus on determining how gain and loss of function of key proteostasis regulators and human mutations that compromise cellular proteostasis influence the fate and malignancy in HSPCs. Other key aspects of this research are to understand signals that control proteostasis regulators in normal and malignant HSPCs and to develop reagents that therapeutically modulate proteostasis pathways in blood cell diseases.

Posttranslational regulation of immune cell development and function

How immune cells precisely integrate signals from antigen or cytokine receptors into their fate and function remains a long-standing question in immunology. Guided by our previous findings of its ability to tune client protein abundance posttranslationally in response to the quantity of antigen receptor signal in thymocytes, we are investigating how the accessory ESCRT protein CHMP5 is utilized by adaptive and innate immune cells to integrate receptor signals that shape systemic and tissue immunity. We also explore how CHMP5-nucleated pathways might be coopted to enable malignant blood cell homeostasis.

Dr. Adoro received his B.Sc. and M.Sc. at the University of Ibadan in Nigeria. Upon completing his Ph.D. in Immunology at the University of Pennsylvania in Philadelphia, he went on to do a postdoctoral fellowship at the Harvard School of Public Health in Boston and Weill Cornell Medicine in New York.

After his postdoctoral training, Dr. Adoro became a member of the faculty at the Dana Farber Cancer Institute, affiliated with Harvard Medical School, Boston. In 2017, he was recruited as a tenure-track assistant professor in the Department of Pathology at Case Western Reserve University School of Medicine in Cleveland. He is the recipient of an NCI Career Development Award, an American Cancer Society Research Scholar Award, and the Michael E. Lamm Award for Graduate Student Teaching from the Department of Pathology, Case Western Reserve University School of Medicine. Dr. Adoro joined the NCI in August 2022 as an Earl Stadtman Tenure-Track Investigator.
