Article Abstract
This study employed transcriptome sequencing and targeted metabolomics to delve into the molecular alterations in mouse spinal cords following spinal cord injury (SCI). Notably, a significant depletion of pantothenic acid (PA) was observed in the injured spinal cord, exhibiting an inverse correlation with microglial inflammation and activation. To further elucidate this relationship, experimental interventions using PA were conducted in SCI mouse models. The results demonstrated that PA administration effectively inhibited microglial inflammation via modulation of the JAK2/STAT3 signaling pathway. This inhibition not only mitigated the neuroinflammatory milieu but also fostered an environment conducive to axonal growth and neuronal regeneration. Consequently, SCI mice treated with PA exhibited improved motor function recovery compared to untreated controls. Our findings not only deepen the understanding of the relationship between PA and neuroinflammatory processes in SCI but also highlight the therapeutic potential of PA in promoting neuronal regeneration and functional recovery.

Microglial activation-induced neuroinflammation and impaired neuronal mitophagy are recognized as pivotal pathogeneses in Parkinson's disease (PD). However, the role of microglial mitophagy in microglial activation during PD development remains unclear, and therapeutic interventions targeting this interaction are lacking. Rhapontigenin (Rhap), a stilbenoid enriched in Vitis vinifera, exhibits dual anti-neuroinflammatory and mitophagy-enhancing properties, but its therapeutic potential and mechanisms in PD are unexplored.

Alzheimer's disease (AD) is influenced by genetic and environmental factors. Previous studies showed that enriched environments improved memory and reduced amyloid plaques in AD mice, but the underlying mechanisms remain unclear. This study investigated the effects and mechanisms of enriched environments on AD pathology and cognitive function in aged APP/PS1 mice.

Polar metabolic profiling, as well as bioenergetic assays, were used to characterize microglial responses to lipopolysaccharide, which induces a pro-inflammatory state, and interleukin-4, which is associated with an anti-inflammatory phenotype. BV2 microglial cells and primary microglia were used for these investigations. Results revealed that lipopolysaccharide-treated microglia exhibited an increased aerobic glycolytic activity measured by extracellular flux analysis, accompanied by increased levels of endogenous itaconate, a metabolite produced by the IRG1 enzyme.

Neuroinflammation plays a pivotal role in the initiation and progression of cognitive impairments. Hv1 channels have been implicated in proton extrusion, microglial activation, and neuroinflammation onset. Despite this, the specific mechanisms by which Hv1 deficiency mitigates neuroinflammation and its impact on pathophysiological processes are not fully understood.

It is currently unknown how microglial reactivity progresses and contributes to seizure development following Theiler's Murine Encephalomyelitis Virus (TMEV) infection. Previously, our group has demonstrated that purinergic signaling in microglia is disrupted in the hippocampus of TMEV-infected mice.
