Margarita Dionysiou Has Been Awarded St. Baldrick’s Fellowship for Leukemia Research – Johns Hopkins Kimmel Cancer Center
Johns Hopkins Kimmel Cancer Center shared a post on LinkedIn:
“Margarita Dionysiou, a pediatric hematology/oncology fellow at The Johns Hopkins University School of Medicine, has been awarded a fellowship grant from the St. Baldrick’s Foundation to support her research in childhood leukemia. The fellowship provides two to three years of funding for early-career scientists working to improve outcomes for children with cancer.
Dionysiou’s research focuses on improving the safety and effectiveness of allogeneic hematopoietic cell transplantation (allo-HCT) – a potentially curative treatment for children with aggressive leukemias. While powerful, this treatment can cause a serious complication known as graft-versus-host disease (GVHD), in which immune cells from the donor attack the child’s healthy tissues.
Her project investigates miR-21, a molecule naturally made by the body, which plays a role in regulating the immune system. By studying how miR-21 controls immune responses after transplant, Dionysiou aims to prevent GVHD while preserving the donor cells’ ability to fight leukemia – making stem cell transplants safer and more effective for children.
The St. Baldrick’s Foundation has awarded more than $1.4 million in fellowships to support the next generation of pediatriccancer researchers.”
