Abstract
As per the World Health Organization (WHO) estimation, Alzheimer's disease (AD) will affect 100 million population across the globe by 2050. AD is an incurable neurodegenerative disease that remains a mystery for neurologists owing to its complex pathophysiology. Currently, available therapeutic regimens will only cause symptomatic relief by improving the cognitive and behavioral functions of AD. However, the major pitfalls in managing AD include tight junctions in the endothelial cells of the blood-brain barrier (BBB), diminished neuronal bioavailability, enzymatic degradation and reduced stability of the therapeutic moiety. In an effort to surmount the drawbacks mentioned above, researchers shifted their focus toward nanocarriers (NCs). Nevertheless, non-specific targeting of NCs imparts toxicity to the peripheral organs, thereby reducing the bioavailability of therapeutic moiety at the target site. To unravel this unmet clinical need, scientists came up with the idea of a novel intriguing strategy of surface engineering by targeting ligands. Surface-decorated NCs provide targeted drug delivery, controlled drug release, enhanced penetration and bioavailability. In this state-of-the-art review, we have highlighted in detail various molecular signalling pathways involved in AD pathogenesis. The significance of surface functionalization and its application in AD management have been deliberated. We have elaborated on the regulatory bottlenecks and clinical hurdles faced during lab-to-industrial scale translation along with possible solutions.

Abstract
Rivastigmine hydrogen tartrate (RHT) is an acetylcholinesterase (AChE) inhibitor used in the management of Alzheimer's disease (AD). RHT is a BCS class-I drug that undergoes significant first-pass metabolism. Permeating a hydrophilic drug through the brain remains a major challenge in brain delivery. In this study, the RHT was incorporated inside the hydrophilic core of liposomes (LPS) and then coated with the ApoE3. ApoE3-coated RHT-loaded liposomes (ApoE3-RHT-LPS) were fabricated through the thin film hydration method using DSPE-PEG. The coating of LPS with ApoE3 enhances brain uptake and improves Aβ clearance. The results obtained from the physicochemical characterization demonstrated that ApoE3-RHT-LPS shows a particle size of 128.6 ± 2.16 nm and a zeta potential of 16.6 ± 1.19. The % entrapment efficiency and % drug loading were found to be 75% and 17.84%, respectively. The data obtained from TEM and SEM studies revealed that the particle size of the LPS was less than 200 nm. An in vitro AChE assay was performed, and the results demonstrated the AChE inhibitory potential of ApoE3-RHT-LPS. Through the intravenous route, an in vivo pharmacokinetic study of formulation displayed improved brain uptake of RHT by ~ 1.3-fold than pure RHT due to ApoE3 coating. In vivo, biodistribution studies in vital organs suggested that the biodistribution of RHT to the liver was significantly reduced (p < 0.001), signifying an increase in the drug's half-life and blood circulation time. All research findings suggested that ApoE3 coating and LPS strategy are proven effective for improving the brain uptake of RHT designed for the management of AD.

Abstract
Trehalose is a disaccharide that is capable of inhibiting protein aggregation and activating cellular autophagy. It has been shown that a polymer or nanoparticle form, terminated with multiple trehalose units, can significantly enhance the anti-amyloidogenic performance and is suitable for the treatment of neurodegenerative diseases. Here, we report a trehalose-conjugated polycarbonate-co-lactide polymer and formulation of its nanoparticles having multiple numbers of trehalose exposed on the surface. The resultant poly(trehalose) nanoparticle inhibits the aggregation of amyloid beta peptides and disintegrates matured amyloid fibrils into smaller fragments. Moreover, the poly(trehalose) nanoparticle lowers extracellular amyloid β oligomer-driven cellular stress and enhances cell viability. The presence of biodegradable polycarbonate components in the poly(trehalose) nanoparticle would enhance their application potential as an anti-amyloidogenic material.

Abstract
Diabetes mellitus is a metabolic disorder characterized by inadequate insulin secretion and signaling dysfunction, leading to a vast spectrum of systemic complications. These complications trigger cascades of events that result in amyloid-beta plaque formation and lead to neurodegenerative disorders such as Alzheimer's. Repaglinide (REP) an insulinotropic agent, suppresses the down regulatory element antagonist modulator (DREAM) and enhances the ATF6 expression to provide neuroprotection following the DREAM/ATF6/apoptotic pathway. However, oral administration of REP for brain delivery becomes more complicated due to its physicochemical characteristics (high protein binding (>98%), low permeability, short half-life (∼1 h), low bioavailability). Therefore, to circumvent these problems, we develop a polymeric nanocarrier system (PNPs) by in-house synthesized di-block copolymer (PEG-PCL). PNPs were optimized using quality by design approach response surface methodology and characterized by particle size (112.53 ± 5.91 nm), PDI (0.157 ± 0.08), and zeta potential (-6.20 ± 0.82 mV). In vitro release study revealed that PNPs (∼70% in 48 h) followed the Korsmeyer-Peppas model with a Fickian diffusion release pattern, and in intestinal absorption assay PNPs showed increment of ∼1.3 folds compared of REP. Moreover, cellular studies confirmed that REP-loaded PNPs significantly enhance the cellular viability, uptake and reduce the peroxide-induced stress in neuroblastoma SHSY-5Y cells. Further, pharmacokinetic parameters of PNPs showed an increment in tmax (2.46-fold), and Cmax (1.25-fold) associated with REP. In the brain biodistribution study, REP loaded PNPs was sustained for 24 h whereas free REP sustained only for12 h. In DM induced neurodegenerative murine model, a significantly (p < 0.01) enhanced pharmacodynamic was observed in PNP treated group by estimating biochemical and behavioral parameters. Hence, oral administration of REP-loaded PNPs promotes efficient brain uptake and improved efficacy of REP in the diseased model.

Abstract
Feralolide, a dihydroisocoumarin, was isolated from the methanolic extract of resin of Aloe vera. The present study aims to investigate the in vivo ability of feralolide to ameliorate memory impairment induced by scopolamine using a battery of in vitro assays, such as antioxidant and acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibition, and in vivo animal models, including elevated plus maze, Morris water maze, passive avoidance, and novel object recognition tests. Feralolide caused a concentration-dependent inhibition of AChE and BuChE enzymes with IC50 values of 55 and 52 μg/mL, respectively, and antioxidant activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) with IC50 values 170 and 220 μg/mL, respectively. Feralolide reversed the scopolamine-induced amnesia as indicated by a dose-dependent decrease in escape latency, path length, and passing frequency in the Morris water maze test compared with the relevant control. The compound also significantly increased the discrimination index in a dose-dependent manner in NORT and decreased transfer latency in EPM, reflective of its memory-enhancing effect. Furthermore, feralolide also caused significant dose-dependent elevation in the step-down latency (SDL) in the passive avoidance test. The results indicated that feralolide might be a helpful memory restorative mediator in treating cognitive disorders such as Alzheimer’s disease.

Abstract
Nano-emulgel is an emerging drug delivery system intended to enhance the therapeutic profile of lipophilic drugs. Lipophilic formulations have a variety of limitations, which includes poor solubility, unpredictable absorption, and low oral bioavailability. Nano-emulgel, an amalgamated preparation of different systems aims to deal with these limitations. The novel system prepared by the incorporation of nano-emulsion into gel improves stability and enables drug delivery for both immediate and controlled release. The focus on nano-emulgel has also increased due to its ability to achieve targeted delivery, ease of application, absence of gastrointestinal degradation or the first pass metabolism, and safety profile. This review focuses on the formulation components of nano-emulgel for topical drug delivery, pharmacokinetics and safety profiles.

Discovery of Taxus chinensis fruit wine as potentially functional food against Alzheimer's disease by UHPLC-QE-MS/MS, network pharmacology and molecular docking. J Food Biochem 2022; 46:e14502. [PMID: 36394096 DOI: 10.1111/jfbc.14502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 09/29/2022] [Accepted: 10/20/2022] [Indexed: 11/18/2022]
Abstract
Nowadays, there is no specific cure for Alzheimer's disease (AD), but the progression of AD can be improved by preventive interventions. The wine of Taxus chinensis fruit (TCFW) has the effect of improving human immunity and anti-aging as a long history of health care wine in folk, especially popular in the longevity villages in China, which may be potentially effective dietary products to improve AD. However, the chemical constituents and molecular mechanisms of TCFW still remain unknown. In this study, chemical profiling with UHPLC-QE-MS/MS, network pharmacology and molecular docking were integrated to fastly explore the potential chemicals and mechanisms of TCFW against AD. A total of 31 chemical components in TCFW were detected and identified compared with the solvent wine of TCFW by UHPLC-QE-MS/MS. Then, 27 potential key targets and 14 chemical compounds of TCFW were uncovered for the improvement of AD by network pharmacology and molecular docking. These 14 compounds were reported to have diverse bioactivities such as neuroprotective activity, antifibrotic activity, anticancer activity, antiviral activity and effectiveness in the treatment of neuronal injury, Alzheimer's disease, etc. Among these 27 targets affected by TCFW predicted by our approach, AKT1, PTGS2, NOS3, NOS2, INS, ESR1, ESR2, BDNF, IL6, IL1B, DRD2 and ACHE were significantly altered in AD. The GO and KEGG enrichment analyses revealed that TCFW mainly acted on oxidative response, inflammatory response, insulin secretion, amyloid fibril formation, neurodegenerative pathway-multiple diseases, Alzheimer's disease, longevity regulation pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, etc, which were the main pathogenesis of AD. PRACTICAL APPLICATIONS: Alzheimer's disease (AD) is a degenerative neurological disorder characterized by cognitive and behavioral dysfunction. Nowadays, there is no specific cure for AD, but the progression of AD can be improved by preventive interventions. The wine of Taxus chinensis fruit (TCFW) has the effect of improving human immunity and anti-aging as a long history of health care wine in folk, especially popular in the longevity villages in China, which may be potentially effective dietary products to improve AD. This study proposed a fastly integrated method to explore the potential chemicals and mechanisms of TCFW against AD by UHPLC-QE-MS/MS, network pharmacology and molecular docking. Here, we found that TCFW may ameliorate AD by reversing many biological events, including oxidative stress, inflammatory response, neuronal apoptosis, insulin secretion, amyloid fibril formation, and T cell co-stimulation, which may provide some insights for the development and research of anti-AD drugs.

Abstract
Alzheimer's Disease (AD) is an irreversible neurodegenerative disease for which no disease modifying therapies are presently available. Besides the identification of pathological targets, AD presents numerous clinical and pharmacological challenges such as efficient active delivery to the central nervous system, cell targeting, and long-term dosing. Nanoparticles have been explored to overcome some of these challenges as drug delivery vehicles or drugs themselves. However, early promises have failed to materialize as no nanotechnology-based product has been able to reach the market and very few have moved past preclinical stages. In this review, we perform a critical analysis of the past decade's research on nanomedicine-based therapies for AD at the preclinical and clinical stages. The main obstacles to nanotechnology products and the most promising approaches were also identified, including renewed promise with gene editing, gene modulation, and vaccines.

Abstract
Insulin resistance (IR) and accumulation of amyloid beta (Aβ) oligomers are potential causative factor for Alzheimer's Disease (AD). Simultaneously, enhanced clearance level of these oligomers through autophagy activation bring novel insights into their therapeutic paradigm. Autophagy activation is negatively correlated with mammalian target of rapamycin (mTOR) and dysregulated mTOR level due to epigenetic alterations can further culminate towards AD pathogenesis. Therefore, in the current study we explored the neuroprotective efficacy of rapamycin (rapa) and vorinostat (vori) in-vitro and in-vivo. Aβ1-42 treated SH-SY5Y cells were exposed to rapa (20 μM) and vori (4 μM) to analyse mRNA expression of amyloid precursor protein (APP), brain derived neurotrophic factor (BDNF), glial cell derived neurotrophic factor (GDNF), neuronal growth factor (NGF), beclin-1, microtubule-associated protein 1A/1B-light chain 3-phosphatidylethanolamine conjugate (LC3), lysosome-associated membrane protein 2 (LAMP2) and microtubule associated protein 2 (MAP2). In order to develop IR condition, rats were fed a high fat diet (HFD) for 8 weeks and then subjected to intracerebroventricular Aβ1-42 administration. Subsequently, their treatment was initiated with rapa (1 mg/kg, i.p.) and vori (50 mg/kg, i.p.) once daily for 28 days. Morris water maze was performed to govern cognitive impairment followed by sacrification for subsequent mRNA, biochemical, western blot and histological estimations. For all the measured parameters, a significant improvement was observed amongst the combination treatment group in contrast to that of the HFD + Aβ1-42 group and that of the groups treated with the drugs alone. Outcomes of the present study thus suggest that combination therapy with rapa and vori provide a prospective therapeutic approach to ameliorate AD symptoms exacerbated by IR.

Abstract
Alzheimer type of dementia is accompanied with progressive loss of cognitive function that directly correlates with accumulation of amyloid beta plaques. It is known that Fibroblast growth factor 21 (FGF21), a metabolic hormone, with strong neuroprotective potential, is induced during oxidative stress in Alzheimer's disease. Interestingly, FGF21 cross-talks with autophagy, a mechanism involved in the clearance of abnormal protein aggregate. Moreover, autophagy activation by Rapamycin delivers neuroprotective role in Alzheimer's disease. However, the synergistic neuroprotective efficacy of overexpressed FGF21 along with Rapamycin is not yet investigated. Therefore, the present study examined whether overexpressed FGF21 along with autophagy activation ameliorated neurodegenerative pathology in Alzheimer's disease. We found that cognitive deficits in rats with intracerebroventricular injection of Amyloid beta1-42 oligomers were restored when injected with FGF21-expressing lentiviral vector combined with Rapamycin. Furthermore, overexpression of FGF21 along with Rapamycin downregulated protein levels of Amyloid beta1-42 and phosphorylated tau and expression of major autophagy proteins along with stabilization of oxidative stress. Moreover, FGF21 overexpressed rats treated with Rapamycin revamped the neuronal density as confirmed by histochemical, cresyl violet and immunofluorescence analysis. These results generate compelling evidence that Alzheimer's disease pathology exacerbated by oligomeric amyloid beta may be restored by FGF21 supplementation combined with Rapamycin and thus present an appropriate treatment paradigm for people affected with Alzheimer's disease.

Abstract
BACKGROUND AND PURPOSE The development of effective therapeutic strategies against Alzheimer's disease (AD) remains a challenge. I2 imidazoline receptor ligands have a neuroprotective role in AD. Moreover, co-treatment of AChE inhibitors with neuroprotective agents have shown better effects on the prevention of dementia. Here, we assessed the potential therapeutic effect of the I2 ligand, donepezil and their combination in 5XFAD mice. EXPERIMENTAL APPROACH 5XFAD female mice were treated with low doses (1 mg·kg-1 ·day-1 ) of LSL60101, donepezil and donepezil plus LSL60101, during 4 weeks per os. Novel object recognition, Morris water maze, open field, elevated plus maze and three-chamber tests were used to evaluate the cognitive and behavioural status after treatment. The effects on AD-like pathology were assessed with immunohistochemistry, western blot, ELISA and qPCR. KEY RESULTS Chronic low-dose treatment with LSL60101 and donepezil reversed cognitive deficits and impaired social behaviour. LSL60101 treatment did not affect anxiety-like behaviour in contrast to donepezil. In the 5XFAD brains, LSL60101 and donepezil/LSL60101 treatments attenuated amyloid-β pathology by decreasing amyloid-β40 and amyloid-β42 levels, amyloid-β plaque number and tau hyperphosphorylation. These alterations were accompanied by reduced microglia marker Iba-1 levels and increased Trem2 gene expression. LSL60101 and donepezil decreased glial fibrillary acidic protein (GFAP) astrocytic marker reactivity. However, only LSL60101 and donepezil/LSL60101 treatments significantly increased the synaptic marker levels of post-synaptic density protein 95 and synaptophysin. CONCLUSION AND IMPLICATIONS Chronic low-dose treatment with selective I2 - ligands can be an effective treatment for AD and provide insights into combination treatments for symptomatic and disease-modifying drugs.

Abstract
Anomalies in brain insulin signaling have been demonstrated to be involved in the pathology of Alzheimer disease (AD). In this context, the neuroprotective efficacy of an insulin sensitizer, rosiglitazone, has been confirmed in our previous study. In the present study, we hypothesize that a combination of an epigenetic modulator, vorinostat, along with rosiglitazone can impart improved gene expression of neurotrophic factors and attenuate biochemical and cellular alteration associated with AD mainly by loading these drugs in a surface modified nanocarrier system for enhanced bioavailability and enhanced therapeutic efficacy. Hence, in this study, rosiglitazone and vorinostat were loaded onto a poloxamer stabilized polymeric nanocarrier system and administered to mice in the intracerebroventricular streptozotocin (3 mg/kg) induced model of AD. Treatment with the free drug combination (rosiglitazone 5 mg/kg, vorinostat 25 mg/kg) for 3 weeks attenuated the behavioral, biochemical, and cellular alterations as compared to either treatment alone (rosiglitazone 10 mg/kg, vorinostat 50 mg/kg). Further, the coencapsulated nanoformulation (rosiglitazone 5 mg/kg, vorinostat 25 mg/kg) exerted better neuroprotective efficacy than the free drug combination as evidenced by improved behavioral outcome, reduced oxidative stress, and elevated levels of neurotrophic factors. In conclusion, the synergistic neuroprotective efficacy of rosiglitazone and vorinostat has been increased through the poloxamer stabilized polymeric nanocarrier system.

Abstract
Native nanostructured lipoproteins such as low- and high-density lipoproteins (LDL and HDL) are powerful tools for the targeted delivery of drugs and imaging agents. While the cellular recognition of well-known HDL-based carriers occurs via interactions with an HDL receptor, the selective delivery and uptake of LDL particles by target cells are more complex. The most well-known mode of LDL-based delivery is via the interaction between apolipoprotein B (Apo-B) - the main protein of LDL - and the low-density lipoprotein receptor (LDLR). LDLR is expressed in the liver, adipocytes, and macrophages, and thus selectively delivers LDL carriers to these cells and tissues. Moreover, the elevated expression of LDLR in tumor cells indicates a role for LDL in the targeted delivery of chemotherapy drugs. In addition, chronic inflammation associated with hypercholesterolemia (i.e., high levels of endogenous LDL) can be abated by LDL carriers, which outcompete the deleterious oxidized LDL for uptake by macrophages. In this case, synthetic LDL nanocarriers act as 'eat-me' signals and exploit mechanisms of native LDL uptake for targeted drug delivery and imaging. Lastly, recent studies have shown that the delivery of LDL-based nanocarriers to macrophages via fluid-phase pinocytosis is a promising tool for atherosclerosis imaging. Hence, the present review summarizes the use of natural and synthetic LDL-based carriers for drug delivery and imaging and discusses various mechanisms of targeting.

Abstract
The present study investigated the role and potential mechanisms of miR-130a-3p in AD. SH-SY5Y cells were treated with Aβ 1-42 to construct AD cell models. APP/PS1 mice were used for the animal experiments. MiR-130a-3p was downregulated in Aβ-induced SH-SY5Y cells. Overexpression of miR-130a-3p attenuates Aβ induced SH-SY5Y cell apoptosis. Low miR-130a-3p expression was detected in the hippocampus tissues of AD mice. The Morris water maze (MWM) results indicated that miR-130a-3p upregulation reduced the escape latency time and increased the time of AD mice spent in the target quadrant. DAPK1 was the target gene of miR-130a-3p. High DAPK1 mRNA level was detected in Aβ treated PC 12 cells and in the hippocampus tissues of AD mice. It was concluded that overexpression of miR-130a-3p may attenuate Aβ-induced neurotoxicity and improve the cognitive function of AD mice via targeting DAPK1.
