Microglia efferocytosis: an emerging mechanism for the resolution of neuroinflammation in Alzheimer's disease.
Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by significant neuroinflammatory responses. Microglia, the immune cells of the central nervous system, play a crucial role in the pathophysiology of AD. Recent studies have indicated that microglial efferocytosis is an important mechanism for clearing apoptotic cells and cellular debris, facilitating the resolution of neuroinflammation. This review summarizes the biological characteristics of microglia and the mechanisms underlying microglial efferocytosis, including the factors and signaling pathways that regulate efferocytosis, the interactions between microglia and other cells that influence this process, and the role of neuroinflammation in AD. Furthermore, we explore the role of microglial efferocytosis in AD from three perspectives: its impact on the clearance of amyloid plaques, its regulation of neuroinflammation, and its effects on neuroprotection. Finally, we summarize the current research status on enhancing microglial efferocytosis to alleviate neuroinflammation and improve AD, as well as the future challenges of this approach as a therapeutic strategy for AD.
期刊介绍：
The Journal of Neuroinflammation is a peer-reviewed, open access publication that emphasizes the interaction between the immune system, particularly the innate immune system, and the nervous system. It covers various aspects, including the involvement of CNS immune mediators like microglia and astrocytes, the cytokines and chemokines they produce, and the influence of peripheral neuro-immune interactions, T cells, monocytes, complement proteins, acute phase proteins, oxidative injury, and related molecular processes.
Neuroinflammation is a rapidly expanding field that has significantly enhanced our knowledge of chronic neurological diseases. It attracts researchers from diverse disciplines such as pathology, biochemistry, molecular biology, genetics, clinical medicine, and epidemiology. Substantial contributions to this field have been made through studies involving populations, patients, postmortem tissues, animal models, and in vitro systems.
The Journal of Neuroinflammation consolidates research that centers around common pathogenic processes. It serves as a platform for integrative reviews and commentaries in this field.
