Sex is a key modifier of neurological disease outcomes. Microglia are implicated in neurological diseases and modulated by microRNAs, but it is unknown whether microglial microRNAs have sex-specific influences on disease. We show in mice that microglial microRNA expression differs in males and females and that loss of microRNAs leads to sex-specific changes in the microglial transcriptome and tau pathology. These findings suggest that microglial microRNAs influence tau pathogenesis in a sex-specific manner.

Elevated inflammatory reactions are a significant component in cerebral ischemia-reperfusion injury (CIRI). Activation of α7-Nicotinic Acetylcholine Receptor (α7nAChR) reduces stroke-induced inflammation in rats, but the anti-inflammatory pathway in microglia under CIRI condition remains unclear. This study employed qRT-PCR, protein assays, NanoString analysis, and bioinformatics to examine the effects of PNU282987 treatment (α7nAChR agonist) on BV2 microglial functional differentiation in oxygen-glucose deprivation/reoxygenation (OGDR) condition.

Historically, microglial activation has been associated with diseases of a neurodegenerative and neuroinflammatory nature. Some, like Alzheimer's disease, Parkinson's disease, and multiple system atrophy, have been explored extensively, while others pertaining to metabolism not so much. However, emerging evidence points to hypothalamic inflammation mediated by microglia as a driver of metabolic dysregulations, particularly insulin resistance and type 2 diabetes mellitus.

Neuropathic pain is a chronic pain condition that is primarily caused by underlying neurological damage and dysfunction. Recent studies have identified microRNAs (miRNAs) as a key factor in the treatment of neuropathic pain. To explore the effects of miR-133a-3p on neuroinflammation and neuropathic pain via GTP cyclohydrolase (GCH1), and its underlying mechanisms.

Aim: Severe painful neuropathy often occurs in cancer patients receiving chemotherapy. Emerging evidence has demonstrated that microglia contribute to the occurrence and development of cancer-associated pain. This study aimed to investigate the mechanisms by which piperine influences cancer-associated pain induced by microglia activation.

Research on epigenetic‒environmental interactions in the development of Alzheimer's disease (AD) has accelerated rapidly in recent decades. Numerous studies have demonstrated the contribution of ambient particulate matter (PM) to the onset of AD. Emerging evidence indicates that non-coding RNAs (ncRNAs), including long non-coding RNAs, circular RNAs, and microRNAs, play a role in the pathophysiology of AD.
