In neurodegenerative diseases, neuronal damage caused by neuroinflammation is very important. Many studies have suggested that the activation of microglia is critical for the neuroinflammatory process. Therefore, inhibiting neuroinflammation is considered to be a hopeful target for curing neurodegenerative diseases. In this study, we aimed to explore whether menthol can protect the dopaminergic neurons by exerting anti-inflammatory effects in vivo or in vitro. The results showed that menthol had an inhibitory effect on impaired dopaminergic neurons and LPS-induced microglial activation. Further, menthol can inhibit the expression of related pro-inflammatory enzymes and pro-inflammatory factors. Both in vitro and in vivo mechanistic studies showed that menthol inhibited the neuroinflammatory response through the MAPK, NF-κB and AKT signaling pathways.

Emerging evidence highlights the significance of peripheral inflammation in the pathogenesis of Parkinson's disease (PD) and suggests the gut as a viable therapeutic target. This study aimed to explore the neuroprotective effects of the probiotic formulation VSL#3 and its underlying mechanism in a PD mouse model induced by MPTP. Following MPTP administration, the striatal levels of dopamine and its metabolites, as along with the survival rate of dopaminergic neurons in the substantia nigra, were significantly reduced in PD mice.

Parkinson's disease (PD) is a chronic neurodegenerative disorder marked by dopaminergic neuron degeneration in the substantia nigra. Emerging evidence suggests vitamin D3 (VD) plays a therapeutic role in PD, but its precise molecular mechanisms remain unclear. This study employed network pharmacology and bioinformatics to identify VD's hub targets and related pathways.

Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder characterized by the progressive loss of nigrostriatal dopaminergic neurons (DA) which can be caused by environmental and genetic factors. lncRNAs have emerged as an important regulatory layer in neurodegenerative disorders, including PD. In this study, we investigated and validated lncRNAs that may serve as diagnostic or therapeutic targets for PD.

Dopaminergic (DA) neurons of the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) play a crucial role in controlling animals' orienting and approach behaviors toward relevant environmental stimuli. The ventral midbrain receives sensory input from the superior colliculus (SC), a tectal region processing information from contralateral receptive fields of various modalities. Given the significant influence of dopamine release imbalance in the left and right striatum on animals' movement direction, our study aimed to investigate the lateralization of the connection between the lateral SC and the midbrain DA system in male rats.
