This review explores how IR promotes amyloidogenesis by disrupting cholesterol homeostasis and enhancing Amyloid beta (Aβ) production and aggregation. Specifically, we examine the role of ATP-binding cassette (ABC) transporters in cholesterol homeostasis along with their impact on insulin signaling pathways, highlights how their dysregulation can lead to IR, a significant contributor to the development of amyloidogenesis, a key factor in causing NDDs. We explore the novel molecular mechanisms linking IR and Aβ aggregation, focusing on the interplay between ABC transporters and Amyloid precursor protein (APP) processing. Furthermore, we also explore emerging evidence linking ABC transporters to oxidative stress, inflammation and mitochondrial dysfunction critical factors in the development of amyloidogenesis. Additionally, this review also discusses potential therapeutic strategies targeting ABC transporters to mitigate IR and reduce amyloid burden by various mechanisms including Insulin receptors/IRS-1 signaling, Phosphatidylinositol3kinase-Protein kinase-B (PI3K/AKT), Mitogen-activated protein kinases (MAPK), c-Jun N-terminal kinase (JNK), Glycogen synthase kinase 3 (GSK3), mammalian Target of Rapamycin (mTOR), Insulin-Degrading Enzyme (IDE), Advanced glycation end products (AGEs), Glucose transporters (GLUTs), Apolipoprotein E (ApoE), Peroxisome proliferator-activated receptors (PPARs), Adiponectin, Mitochondrial dysfunctioning, AMP-activated protein kinase (AMPK) Wingless-related integration site/beta-catenin (Wnt/β-catenin) and Sirtuin1 (SIRT1).

TUNEL staining of hippocampus neurons revealed that the number of apoptotic neurons was elevated 24 h after reperfusion. At the molecular levels, I/R injury resulted in an increased protein expression of cleaved caspase3/procaspase3 ratio and cytochrome c level with a concomitant down-regulation of NGF, p-AKT/AKT, p-Bad/Bad and p-Trk/Trk ratio. NAC treatment significantly reduced the apoptotic damage and also reversed NGF, p-AKT/AKT, p-Bad/Bad, and p-Trk/Trk ratio in hippocampus neurons in I/R rats. In conclusion, our data showed that NGF-Akt/Bad axis may play a regulatory role in hippocampus cell death, providing a new target for a novel therapeutic strategy during transit ischemic stroke.

The gut microbiota composition of SAMP8 mice treated with PRG was analyzed using 16S rRNA gene sequencing. Non-targeted metabolomics, based on ultra-performance liquid chromatography quadrupole/electrostatic field orbitrap high-resolution mass spectrometry, was employed to analyze changes in metabolites in the serum samples. Spearman correlation analysis was further used to explore the association between gut microbiota and serum metabolites. PRG significantly improved gut dysbiosis in SAMP8 mice by increasing the abundance of beneficial bacterial genera, reducing pathogenic bacteria levels, and restoring the dominance of advantageous bacterial phyla. Serum metabolomics analysis revealed that PRG intervention led to significant changes in AD-related metabolites, including phenylalanine and oxidative stress markers. Combined analysis indicated a correlation between changes in gut microbiota and serum metabolites.

Forty robust male ICR mice were randomly categorized into 4 groups and received intraperitoneal injections (i.p.) of peanut oil or B[a]P at doses of 0.5, 2, or 10 mg/kg, 30 times over a period of 60 days. Behavioral assessments were conducted to evaluate depression-like symptoms, identify neuronal structural alterations and cellular apoptosis, and measure the protein levels of brain-derived neurotrophic factor (BDNF), tropomyosin receptor kinase B (TrkB), phosphorylated TrkB (p-TrkB), cAMP-response element binding protein (CREB) and phosphorylated CREB (p-CREB) in the cerebral cortex.

The interaction between miR-134-5p and BDNF mRNA was examined, along with its inhibitory effects in both in vivo and in vitro contexts.
