WebApr 3, 2024 · Recent genetic evidence supports a link between microglia and the complement system in Alzheimer’s disease (AD). In this study, we uncovered a novel role for the microglial complement receptor 3 (CR3) in the regulation of soluble β-amyloid (Aβ) clearance independent of phagocytosis. Unexpectedly, ablation of CR3 in human … WebNov 6, 2024 · This crosstalk regulates the pathological process of many neurological diseases, such as ischemia, epileptics, and Alzheimer’s. 20–25 These studies indicated that aberrant microglia activation was attenuated together with alleviated neurological symptoms by blocking the C3-C3aR pathway.
WebJan 7, 2015 · C3aR is expressed in both neurons and astroglia, and, therefore, it is plausible that astroglial C3aR may have contributed to the effects of C3aR manipulation in our coculture system. To rule out this possibility, we tested whether loss of neuronal C3aR would abrogate dendritic phenotypes when cultured with IκBα KO astrocytes.
