Cooperation of Factor VII–Activating Protease and Serum DNase I in the Release of Nucleosomes From Necrotic Cells

Removal of dead cells is essential in the maintenance of tissue homeostasis, and efficient removal prevents exposure of intracellular content to the immune system, which could lead to autoimmunity. The plasma protease factor VII–activating protease (FSAP) can release nucleosomes from late apoptotic cells. FSAP circulates as an inactive single‐chain protein, which is activated upon contact with either apoptotic cells or necrotic cells. The purpose of this study was to investigate the role of FSAP in the release of nucleosomes from necrotic cells.
