Craniospinal irradiation (CSI) has long been a cornerstone in the treatment of MB, especially for patients with high-risk or metastatic disease. However, CSI often leads to long-term neurocognitive deficits, including learning disabilities, and growth abnormalities, especially in children. In this study, we aimed to decrease the dose of irradiation and the proliferation of MB by using Volasertib (VSB), a Polo-like kinase 1 (PLK1) specific inhibitor. VSB was highly potent in-vitro with an IC<sub>50</sub> of 27.43 nM and 13 nM in HDMB03 and DAOY cells, respectively. However, in the orthotopic MB mouse model, VSB as a free drug did not improve overall survival or decrease tumor burden. Hence, we encapsulated VSB in COG133-conjugated lipid nanoparticles (COG133-LNPs) to circumvent the blood-brain barrier (BBB). We observed that COG-133-LNPs loaded with VSB increased the biodistribution of VSB by three folds than the non-targeted LNPs in the brain. Furthermore, COG133-LNPs along with irradiation decreased tumor burden significantly as compared to VSB or radiation alone. To our observation, COG133-LNPs display high potency in killing MB cells and sensitizing them toward radiation therapy.","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":"5 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hydrogel, termed HA-CPP⸦CB (Cabrita et al., 2020 [<span><span>8</span></span>]), is formed by supramolecular interactions between 4-(4-chlorophenyl)pyridine modified hyaluronic acid (HA-CPP) and cucurbit [<span><span>8</span></span>]uril (CB (Cabrita et al., 2020 [<span><span>8</span></span>])). The results reveal that a single injection of HA-CPP⸦CB (Cabrita et al., 2020 [<span><span>8</span></span>]) hydrogel containing the CXCL13 chemokine and LIGHT cytokine effectively increases TLSs density, facilitates mature TLSs formation, suppresses tumor growth, and extends survival. Importantly, the hydrogel treatment also up-regulates the number of antigen-specific T-cells in the secondary lymphoid organs. Furthermore, combination of the hydrogel-based drug formulation and the anti-PD1 ICB therapy results in increased tumor suppression, improved survival rates, and strengthened TLSs formation, ultimately contributing to B16-OVA melanoma eradication.

Recent advancements have highlighted the potential of reactive oxygen species (ROS)-responsive drug delivery systems in cancer therapy. In this study, we introduce a novel treatment approach utilizing a ROS-responsive camptothecin (CPT) prodrug encapsulated within chitosan nanocarrier, named CACPT. Cinnamaldehyde (CA), acting as a ROS generator, forms thioketal bonds with CPT to create a prodrug that responds selectively to the elevated ROS levels within the tumor microenvironment. Upon exposure to high ROS conditions, these thioketal bonds are cleaved, resulting in the simultaneous release of CPT and CA. The liberated CA further enhances ROS production, establishing a positive feedback loop that amplifies the therapeutic effect. The use of amphiphilic chitosan nanocarriers enhances the retention and penetration of the prodrug within bladder tissue, optimizing its therapeutic potential. Our experimental findings demonstrate that this self-enhanced ROS-responsive release promotes increased cellular uptake and significantly enhances the anticancer efficacy of CACPT. These results position CACPT as a promising candidate for orthotopic infusion therapy in bladder cancer, potentially overcoming current limitations in treatment options. The innovative combination of ROS-responsive mechanisms and chitosan nanocarriers represents a paradigm shift in bladder cancer therapeutics, offering a multifaceted approach with substantial promise for clinical translation.","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":"26 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It significantly increases the risk of fractures, reduces quality of life, and adds to the medical burden. Traditional formulations, such as alfacalcidol (ALF) capsules and tablets, have limitations, including difficulties in swallowing and patient resistance to long-term medication use, highlighting the urgent need for a sustained-release ALF formulation. To address this, we developed a double-layered core-shell microneedle patch integrated with ALF-loaded microparticles for the long-acting treatment of osteoporosis. This system aims to reduce administration frequency and improve patient compliance. After application for just 5 min, the patch can be removed, leaving the microneedle tips embedded in the skin. The core-shell structure of the tip consists of a core made of ALF-loaded polylactic-<em>co</em>-glycolic acid (PLGA) microparticles and a shell composed of ethylcellulose (EC). This structure acts as a drug reservoir within the skin, enabling for sustained release of ALF over 14 days. Compared to commercially available ALF tablets which require daily administration, the long-acting ALF double-layered core-shell microneedle patch (ALF-DCSMN) delivers a lower systemic drug dose while demonstrating comparable or better efficacy in increasing bone mass and improving trabecular microstructure. Notably, ALF-DCSMN only requires semimonthly administration. Overall, these promising results suggest that the ALF-DCSMN is a safe, effective, and user-friendly transdermal formulation for the long-acting treatment of osteoporosis.","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":"5 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prolonging the residence time of oral DDSs in the gastrointestinal tract is indispensable in realizing these goals. However, the hostile gastric environment is not suitable for the retention of susceptible drugs. Intestinal retentive DDSs are promising alternatives for the oral delivery of these drugs. Moreover, intestinal retentive DDSs can provide opportunities for the regulation of mucosal immunity and gut microbiota. In this review, we briefly describe the general information of intestinal transit time and its influencing factors. We next summarize the recent advances of engineering strategies in prolonging the intestinal retention of oral DDSs at nano-, micro-, and macro-scales. While the underlying mechanisms of intestinal retention remain incompletely understood, we discuss the potential theories and evidence.

Accelerating the translation of innovative, effective, and safe treatments is needed to augment existing measures to counteract such a crisis. Active immunization against F/FA and other opioids represents a promising therapeutic and prophylactic strategy for opioid use disorder (OUD) and opioid-induced overdose toxicity. Previously we demonstrated that a vaccine against F/FA comprising a fentanyl-based hapten (F) conjugated to the diphtheria cross-reactive material (CRM), admixed with the novel lipidated toll-like receptor 7/8 (TLR7/8) agonist INI-4001 adsorbed on Alhydrogel® (alum) induced high-affinity fentanyl-specific polyclonal antibodies that protected against fentanyl-induced pharmacological effects in mice, rats, and mini-pigs. Here, INI-4001 was formulated into liposomes with different surface charges, and their impact on F-CRM adsorption, INI-4001 adjuvanticity, and vaccine efficacy were explored. Additionally, as the role of innate immunity in mediating the efficacy of addiction vaccines is largely unknown, we tested these formulations on the activation of innate immunity <em>in vitro</em>. Cationic INI-4001 liposomes surpassed other liposomal and aluminum-based formulations of INI-4001 by enhancing the efficacy of fentanyl vaccines and protecting rats against bradycardia and respiratory depression by blocking the distribution of fentanyl to the brain.
