Research Description: Hematopoiesis and Bone Marrow Function: Molecular Mechanisms Mediating Resistance to Oxidative Stress and Novel Approaches for Therapeutic Intervention.
The process of hematopoiesis in the bone marrow continuously generates all the cells of the blood and immune system and its disruption results in severe and life threatening disorders, including immunodeficiencies, anemias, bone marrow failures, and malignancies. My research group will investigate the cellular and molecular mechanisms of hematopoiesis, especially focusing on the following questions: (i) bone marrow ageing and the mechanisms mediating the long-term resistance of bone marrow stem cells to oxidative stress; (ii) the roles of the H2A-DUB (histone H2A-deubiquitinase) family of chromatin modifying factors in bone marrow function and stem cell resistance to oxidative stress; (iii) development of bioactive peptides for modulation of hematopoiesis and bone marrow function.
