Inflammation plays a crucial role in tissue regeneration and in the development of cancer. Neutrophils are the dominating cell type during acute inflammation. Neutrophils are capable of releasing their DNA from the nucleus into the extracellular environment to form extracellular webs known as Neutrophil Extracellular Traps (NETs).

In order to release its DNA, the nucleus of neutrophils undergoes certain morphological changes which are summarized in the process of NETosis. Once liberated into the extracellular environment, DNA forms a fibrous network, which resembles the appearance of a spider web. NETs can interact with other cells and proteins and the goal of this project is to understand their role in liver regeneration and cancer.
