Protective and healing effects of apoptotic mimic-induced M2-like macrophage polarization on pressure ulcers in young and middle-aged mice

Pressure ulcers (PUs) have no cure and are of significant health and economic concern worldwide, owing to the increasing population of elderly individuals at high risk for PU and who have impaired tissue repair. Macrophages play a pivotal role in PU development and healing. Imbalances between M1 (inflammatory) and M2 (anti-inflammatory/reparative) macrophages result in delayed resolution of inflammation and wound healing. We hypothesized that...
