Role of macrophage CD44 in the disposal of inflammatory cell corpses.
Understanding the cellular and molecular mechanisms that determine whether inflammation resolves or progresses to scarring and tissue destruction should lead to the development of effective therapeutic strategies for inflammatory diseases. Apoptosis of neutrophil granulocytes is an important determinant of the resolution of inflammation, providing a mechanism for down-regulation of function and...
متن کاملMannose-binding lectin is required for the effective clearance of apoptotic cells by adipose tissue macrophages during obesity.
Obesity is accompanied by the presence of chronic low-grade inflammation manifested by infiltration of macrophages into adipose tissue. Mannose-binding lectin (MBL), a soluble mediator of innate immunity, promotes phagocytosis and alters macrophage function. To assess the function of MBL in the development of obesity, we studied wild-type and MBL(-/-) mice rendered obese using a high-fat diet (...
متن کاملMacrophage apoptosis exerts divergent effects on atherogenesis as a function of lesion stage.
BACKGROUND Because apoptotic cell clearance appears to be defective in advanced compared with early atherosclerotic plaques, macrophage apoptosis may differentially affect plaque progression as a function of lesion stage. METHODS AND RESULTS We first evaluated the impact of targeted protection of macrophages against apoptosis at both early and advanced stages of atherosclerosis. Increased res...
متن کاملSelective Depletion of Eosinophils or Neutrophils in Mice Impacts the Efficiency of Apoptotic Cell Clearance in the Thymus
Developing thymocytes undergo a rigorous selection process to ensure that the mature T cell population expresses a T cell receptor (TCR) repertoire that can functionally interact with major histocompatibility complexes (MHC). Over 90% of thymocytes fail this selection process and die. A small number of macrophages within the thymus are responsible for clearing the large number of dying thymocyt...
متن کاملContrasting Inflammation Resolution during Atherosclerosis and Post Myocardial Infarction at the Level of Monocyte/Macrophage Phagocytic Clearance
In cardiovascular disorders including advanced atherosclerosis and myocardial infarction (MI), increased cell death and tissue destabilization is associated with recruitment of inflammatory monocyte subsets that give rise to differentiated macrophages. These phagocytic cells clear necrotic and apoptotic bodies and promote inflammation resolution and tissue remodeling. The capacity of macrophage...
