About the Scientist

Nefedova’s research focuses on understanding molecular mechanisms by which the bone marrow microenvironment promotes tumor survival and progression.

Nefedova obtained her M.D. and Ph.D. degrees at the Pavlov State Medical University of St. Petersburg, Russia. She then pursued postdoctoral training at the H. Lee Moffitt Cancer Center and Research Institute in Tampa, FL, where she began her research in multiple myeloma. In 2013, Nefedova joined The Wistar Institute as an assistant professor in the Tumor Microenvironment and Metastasis program, and was promoted to associate professor in the Immunology, Microenvironment and Metastasis Program in 2017.

The Nefedova Laboratory

The Nefedova laboratory focuses on understanding the role of the bone marrow microenvironment in regulating tumor progression and therapy resistance. The laboratory primarily studies multiple myeloma, a cancer of plasma cells that localizes in the bone marrow. 
 
The laboratory is interested in mechanisms by which interactions between neutrophils in the bone marrow and multiple myeloma cells promote disease progression and chemoresistance. They are investigating the implication of neutrophil extracellular traps (NETs) — structures composed of chromatin and neutrophil proteins — in myeloma progression, and targeting a process of NET formation for treatment of multiple myeloma. The laboratory is also interested in the role of the S100A9 protein, highly expressed by neutrophils, in the pathogenesis of multiple myeloma.
