Recent research suggested that sodium-glucose cotransporter-2 (SGLT-2) inhibitors can mitigate memory impairment linked to Alzheimer's disease and are now being explored for their cognitive benefits. However, their mechanisms were not thoroughly studied. This research investigates the hypothesis of the neuroprotective effect of empagliflozin administration against scopolamine-heavy metal mixture (SCO + HMM)-treated Alzheimer's rat models in comparison with memantine as a reference drug and the impact of their combination. Yet, the neuroprotective effects of memantine and empagliflozin combination against cognitive impairment have not been previously explored. This study employed adult male albino rats categorized into five groups. The impact of empagliflozin, memantine, and their concomitant administration on cognitive performance was assessed in a scopolamine and heavy metal mixture-treated Alzheimer's disease model in rats. The assessment of rats' cognitive behavior, memory, and spatial learning was conducted, followed by an evaluation of hippocampal brain-derived neurotrophic factor (BDNF), beta-secretase (BACE-1), oxidative stress (OS), and inflammatory marker activity. And, a western blot analysis was conducted to detect phosphorylated 5' AMP-activated protein kinase (p-AMPK), phosphorylated mammalian target of rapamycin (p-mTOR), and heme oxygenase-1 (HO-1). Hippocampal and cerebellar histopathology were thoroughly examined, in addition to the expressions of amyloid β (Aβ). The current data demonstrate the involvement of the pAMPK/mTOR/HO-1 signaling pathway in empagliflozin neuroprotection against SCO + HMM-induced AD. In addition, it reduces AD hallmarks (Aβ and BACE1), neuro-inflammation, and oxidative stress sequelae, and enhances neurogenesis and synaptic density via BDNF. This study proposes that EMPA, especially when co-administered with other conventional anti-Alzheimer therapy, may be formulated into an innovative therapeutic strategy for the enhancement of cognitive impairments associated with neurodegenerative disorders.</p>","PeriodicalId":13551,"journal":{"name":"Inflammopharmacology","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143984491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To model this pathological link, our AD-like model was developed by feeding Wistar male rats a high-fat diet with fructose in drinking water (HFFD) for 8 weeks, followed by a single dose of lipopolysaccharide (LPS). This group was compared with a normal control group fed a standard diet and a β-hydroxybutyrate (BHB)-treated group (125 mg/kg, p.o.), administered starting 3 h after LPS and continuing for 1 week. The results demonstrate that BHB treatment illuminated cognitive gains, as indicated by the Y-maze, Morris water maze, and novel object recognition tests. In addition, it preserved hippocampal cytoarchitecture, reduced neurodegeneration, and attenuated amyloid plaques and phosphorylated Tau deposition. Cellularly, BHB restored critical molecular mechanisms, including increased lysosomal-associated membrane protein 2A (LAMP2A) hippocampal content as the main marker of chaperone-mediated autophagy (CMA), along with the chaperon protein Hsp70. Moreover, BHB alleviated neuroinflammation by inhibiting the nucleotide-binding domain, leucine-rich-containing family, and pyrin domain-containing-3 (NLRP3) inflammasome activation alongside the downstream targets cleaved caspase-1 and IL-1β/IL-18 cytokines. BHB also reduced pyroptotic markers, caspase-11 and gasdermin-N, and microglia-induced inflammation as it shifted microglial polarization toward the neuroprotective M2 phenotype. Finally, BHB normalized hippocampal neurotransmitter levels of the inhibited acetylcholine and serotonin.

The progression of AD depends on two main pathologic features, amyloid-beta accumulation, and tau pathology, whereas the disruption of glutamatergic neurotransmission plays an essential role in disease progression. Glutamate, the brain's primary excitatory neurotransmitter, acts on ionotropic and metabotropic glutamate receptors (mGluRs). Metabotropic glutamate receptor 7 (mGluR7) is a pre-synaptic type III mGluR receptor playing a crucial role in the central nervous system (CNS) through neurotransmitter modulation, reducing glutamate-induced excitotoxicity, and promoting early neuronal growth. Since mGluR7 is a key regulator of neurotransmitter release, it modulates synaptic integrity and neuronal survival, and its dysfunction is associated with impaired synaptic homeostasis in AD. Moreover, mGluR7 interacts with neuroinflammatory pathways by activating microglia and regulating cytokine production, therefore playing a significant role in AD pathogenesis. The drugs targeting mGluR7, including mGluR7 agonists, antagonists, and allosteric modulators, could potentially be among the most effective agents for the treatment of psychiatric disorders, neurodegenerative diseases including AD, as well as neurodevelopmental impairments, though these potential therapies remain in the early stages. This article summarises the structure as well as the function of mGluR7 and explores current insights into the functioning of mGluR7 in molecular mechanisms of AD pathogenesis.

The mRNA expression of different inflammatory genes was evaluated by qRT-PCR. Effects of ICE were noted by histological and radiological findings. Phytochemistry of ICE identified the presence of different secondary metabolic constituents and HPLC identified the various phenolic compounds in the extract. Acute oral toxicity results showed that LD<sub>50</sub> of the plant was greater than 2000 mg/kg. ICE demonstrated significant inhibition of egg albumin denaturation and protein denaturation in BSA. In vivo formalin-induced paw inflammation model demonstrated that ICE substantially decreased the severity of inflammation, in a dose-dependent manner. Hematological and biochemical parameters were improved and histological examination revealed reduction in paw inflammation, pannus formation, and bone degradation dose-dependently.
