Skin injury induces a dynamic cellular programme proceeding in sequential phases of antimicrobial defence, followed by tissue growth and differentiation. Cells of the myeloid cell lineage are an essential component of the body’s innate ability to sense tissue damage and to restore tissue function after injury. The aim of this project is to understand the role of mitochondria in myeloid cells in skin homeostasis and repair. Understanding these mechanisms may help developing new therapies to treat patients suffering from impaired healing conditions.
