Assistant Research Professor
Summary of the focus of the research of Dr. Capitano.
Dr. Capitano’s research focuses on discovering potential new agents that regulate hematopoietic stem and progenitor cell migration, proliferation, differentiation and survival capacity under normal and stressed conditions.
Description and summary of my research focus.
Dr. Capitano’s research focuses on how certain environmental conditions, cytokines and endogenous molecules (i.e. danger signals) induced during inflammation may affect hematopoiesis with the ultimate goal of understanding how these danger signals stimulate/regulate the proliferation and differentiation of hematopoietic stem and progenitor cells. One protein that is of particular interest is DEK, a newly recognized danger signal that is implicated in the regulation of transcription, chromatin remodeling and mRNA processing and that may help in maintaining hematopoietic stem cell numbers during inflammation. Dr. Capitano’s research focuses on discovering whether DEK, which is secreted by bone marrow-derived macrophages or by T cells following inflammatory stimuli, plays a role in the resolution of inflammation thus preserving hematopoietic stem cell numbers and returning the bone marrow microenvironment to a more homeostatic level of hematopoiesis.
