Sergio Martinez Hoyer Project
My research aims to understand the cellular and molecular mechanisms underlying the biology and response to therapy in bone marrow diseases, with a focus on myeloid malignancies.
Currently, we are working on two projects:
- Role of innate lymphoid cells in bone marrow fibrosis. Specific genetic alterations in the hematopoietic stem cell compartment can lead to the development of scar tissue in the bone marrow, which then loses its ability to support normal hematopoiesis. Previous work has demonstrated a role for innate lymphocytes in the development of fibrosis in different organs. I am exploring the contribution of innate lymphoid cells to the formation of fibrotic tissue in a mouse model of bone marrow fibrosis.
- Identification of novel therapeutic targets in drug resistant myelodysplastic syndromes. My previous work on resistant MDS described the molecular mechanisms by which malignant cells escape the activity of lenalidomide in the bone marrow. Proof of principle experiments revealed that it should be possible to overcome drug resistance in mutated cells. Using a functional genomics approach on cell lines and primary tissue, we aim to identify novel therapeutic targets that effectively eliminate relapsed malignant cells.
