14-3-3 Proteins Negatively Regulate Microglial Activation via Inhibition of the NF-κB Pathway.

ABSTRACT: Microglia, the resident immune cells of the central nervous system (CNS), are involved in the pathogenesis of neurodegenerative diseases, such as Alzheimer's disease (AD), Dementia with Lewy Bodies (DLB), and Parkinson's disease (PD). 14-3-3 proteins act as molecular hubs to regulate protein-protein interactions, which are involved in numerous cellular functions, including cellular signaling, protein folding, and apoptosis. We previously revealed decreased 14-3-3 levels in the brains of human subjects with neurodegenerative diseases. In this study, we examined the role of 14-3-3 proteins in the microglial proinflammatory response to lipopolysaccharide (LPS). We found that LPS treatment induced 14-3-3 protein levels within 6 hours. With the use of BV02 and dimeric fourteen-three-three pepti
