Аннотация
Severe acute pancreatitis (SAP) is a potentially life-threatening inflammatory disorder of the exocrine pancreas, characterized by massive cell death, which drives the progression and resolution of the disease. However, little is known about the key regulators in the tissue microenvironment that mediate tissue damage and repair. In this study, we discovered that AXL and MERTK in macrophages are responsible for tissue repair and pancreatic inflammation following SAP. Targeted deletion of Axl and Mertk in myeloid cells resulted in impaired phenotypic switch towards pro-resolving macrophage. This impairment is partly due to an accumulation of Cxcr2+ neutrophils and its interaction with Mrc1+/high macrophages likely via CCL4-CCR5 axis. Pancreatic tissue repair was effectively restored by CCR5 inhibition. Collectively, we identify a CCR5-dependent pathway orchestrated by AXL and MERTK in macrophages, which offers a pharmacological target, to promote tissue repair in SAP.
