Jolkinolide B Ameliorates Liver Inflammation and Lipogenesis by Regulating JAK/STAT3 Pathway.

Hepatic dysregulation of lipid metabolism exacerbates inflammation and enhances the progression of metabolic dysfunction-associated steatotic liver disease (MASLD). STAT3 has been linked to lipid metabolism and inflammation. Jolkinolide B (JB), derived from , is known for its pharmacological anti-inflammatory and anti-tumor properties.

Artificial intelligence-driven drug repositioning uncovers efavirenz as a modulator of α-synuclein propagation: Implications in Parkinson's disease.

Parkinson's disease (PD) is a complex neurodegenerative disorder with an unclear etiology. Despite significant research efforts, developing disease-modifying treatments for PD remains a major unmet medical need. Notably, drug repositioning is becoming an increasingly attractive direction in drug discovery, and computational approaches offer a relatively quick and resource-saving method for identifying testable hypotheses that promote drug repositioning.

Zaluzanin C Alleviates Inflammation and Lipid Accumulation in Kupffer Cells and Hepatocytes by Regulating Mitochondrial ROS.

Zaluzanin C (ZC), a sesquiterpene lactone isolated from L., has been reported to have anti-inflammatory and antioxidant effects. However, the mechanistic role of ZC in its protective effects in Kupffer cells and hepatocytes has not been elucidated.

Monitoring α-synuclein Aggregation Induced by Preformed α-synuclein Fibrils in an Model System.

Parkinson's disease (PD) is characterized by the presence of α-synuclein (α-syn) inclusions in the brain and the degeneration of dopamine-producing neurons. There is evidence to suggest that the progression of PD may be due to the prion-like spread of α-syn aggregates, so understanding and limiting α-syn propagation is a key area of research for developing PD treatments. Several cellular and animal model systems have been established to monitor α-syn aggregation and propagation.

Neuronal ApoE Regulates the Cell-to-Cell Transmission of α-Synuclein.

The presence of protein inclusions, called Lewy bodies (LBs) and Lewy neurites (LNs), in the brain is the main feature of Parkinson's disease (PD). Recent evidence that the prion-like propagation of α-synuclein (α-syn), as a major component of LBs and LNs, plays an important role in the progression of PD has gained much attention, although the molecular mechanism remains unclear. In this study, we evaluated whether neuronal ApoE regulates the cell-to-cell transmission of α-syn and explored its molecular mechanism using in vitro and in vivo model systems.

Age-related increase in caveolin-1 expression facilitates cell-to-cell transmission of α-synuclein in neurons.

Parkinson's disease (PD) is the second most prevalent neurodegenerative disease, with aging being considered the greatest risk factor for developing PD. Caveolin-1 (Cav-1) is known to participate in the aging process. Recent evidence indicates that prion-like propagation of misfolded α-synuclein (α-syn) released from neurons to neighboring neurons plays an important role in PD progression.

The dual role of c-src in cell-to-cell transmission of α-synuclein.

Parkinson's disease (PD) is characterized by the loss of dopaminergic neurons located in the substantia nigra pars compacta and the presence of proteinaceous inclusions called Lewy bodies and Lewy neurites in numerous brain regions. Increasing evidence indicates that Lewy pathology progressively involves additional regions of the nervous system as the disease advances, and the prion-like propagation of α-synuclein (α-syn) pathology promotes PD progression. Accordingly, the modulation of α-syn transmission may be important for the development of disease-modifying therapies in patients with PD.
