Here, an upconversion-based strategy is described for remote deep brain modulation, which is an all-optical solution for treating PD in rodent animals without any tethering interferences. It is demonstrated that both high frequency stimulation and inhibition of subthalamic nucleus (STN), can improve the motor function of Hemi-Parkinsonian rodent models, potentially providing a specific and flexible therapeutic alternative for treating PD. A multi-modal approach is further taken that combines optogenetics and electrophysiology recording, and found that high frequency optogenetic inhibition of STN work similarly as high frequency activation to rescue the pathologic electrical activity in the motor cortex and restore the motor deficiency in Hemi-Parkinsonian rodents. It is also shown that indirect inhibitory modification of entopeduncular nucleus (EP) within the basal ganglia system, which is induced by either STN inhibition or activation, plays a critical role in the STN-DBS induced therapeutic effects in the Hemi-Parkinsonian animals. These results provide first experimental evidence supporting a working principle of STN-DBS by disruption of anterograde signal transmission along the indirect pathway of basal ganglia, and can be instructive for future clinical treatment of PD with DBS.</p>","PeriodicalId":7284,"journal":{"name":"Advanced Therapeutics","volume":"8 6","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adtp.202400543","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GBM has an average survival of 12–18 months despite aggressive treatments, such as maximal safe resection, radiation, and chemotherapy with temozolomide. GBM is always associated with high incidences of treatment resistance and recurrence, which is largely driven by glioma stem cells and presents significant therapeutic challenges. The blood–brain barrier (BBB) is the most significant obstacle in treating GBM since it restricts the delivery of therapeutic agents to the tumor site. Recent advancements in nanotechnology offer promising alternatives to overcome such restrictions, enabling targeted drug delivery and significantly reducing systemic toxicity. Additionally, discussing various types of nanoparticles such as liposomes, lipid-based, dendrimers, polymeric, and metallic nanoparticles that have shown promise in preclinical models for GBM treatment has become pertinent. These nanoparticles can attach to glioblastoma cells using antigens and membrane receptors for site-directed drug targeting. Furthermore, nanoparticles have the potential to cross the BBB, enhancing drug delivery and minimizing off-target effects.

However, regeneration of large defects requires the use of grafts. 3D bioprinting is one such promising technology with which bioengineered nerve conduits can be reproduced for the repair of injured peripheral nerves. This review outlines the mechanism of repair and regeneration of peripheral nerves and provides a detailed description of the latest developments in the fabrication of bioengineered nerve conduits. Further, various bioprinting techniques and bioinks that have been established in vitro for the fabrication of nerve conduits are discussed.

Puerarin (Pue), an isoflavone compound, exerts protective effects on ovarian, however, with undefined mechanisms in POF. POF models were established by cyclophosphamide, and Pue and silent information regulator sirtuin 1 (SIRT1) inhibitor Selisistat (EX527) were used. Next, extracted primary rat ovarian granulosa cells (GCs) were treated with EX527 and autophagy activator rapamycin (RA). The data showed that in POF rats, Pue ameliorated estrous cycle, pathological damage, and senescence with higher ovarian index, anti-Müllerianhormone, estradiol, glutathione peroxidase, superoxide dismutase, mitochondrial DNA, and lower luteinizing hormone and follicle-stimulating hormone levels. In GCs, Pue increased cell viability, mitochondrial membrane potential, adenosine triphosphate levels, with decreased senescence and reactive oxygen species.

In this study, PLGA-NPs are prepared using either single- or double-emulsion methods and coated with varying amounts of GC. The results confirmed that GC-coated PLGA NPs are internalized via both clathrin-mediated and caveolae-mediated endocytosis, whereas uncoated NPs relied on only clathrin-mediated endocytosis in Caco-2 and HT-29 cells. The optimized GC-coated PLGA-NPs formulation is further modified by layering alginate to enhance the oral delivery of insulin. In subsequent in vivo studies, the GC and alginate-coated PLGA NPs demonstrated stability and prolonged efficacy, achieving approximately a 50% reduction in blood glucose levels at 6 h post-administration in streptozotocin-induced diabetic mice.
