Abstract
Endometriosis is an inflammation-dependent disorder characterized by the abnormal growth of endometrium-like lesions. In recent years, there is a great deal of interest in the development of anti-inflammatory therapy. Herein, an acid-sensitive calcium carbonate nanoparticle (CaNP) incorporated BML-111 (BML@CaNP) was prepared. BML@CaNP acted as a Ca2+ nanomodulator for efferocytosis (macrophages engulf apoptotic cells). Specifically, BML@CaNP induced the apoptosis of endometriotic stromal cells and enhanced the efferocytosis of macrophages. In addition, the particle can also deliver BML to the ectopic lesion for resolving the inflammatory response. In vivo BML@CaNP effectively suppressed lesion growth in endometriosis mice model, which could be attributed to the enhancing efferocytosis of cells and the lower levels of inflammatory factors in peritoneal fluid. In addition, these nanoparticles did not show side effects. In all, we provide a new anti-inflammatory strategy by both enhancing efferocytosis and resolving inflammation for the treatment of endometriosis.
