This study explores the use of a hyaluronic acid-tyramine (HA-TA) hydrogel to prolong the delivery and enhance the stability of EVs. EVs were obtained from lentiviral-transduced HEK293T cells expressing luciferase and eGFP to enable easy quantification. Two encapsulation strategies were evaluated: (1) pre-loading, where EVs were mixed with HA-TA (2.58 % degree of substitution) precursor solution and subsequently crosslinked with 2 U/mL horseradish peroxidase (HRP) and 0.05 mM H<sub>2</sub>O<sub>2</sub>; and (2) post-loading, where EVs were soaked into pre-formed dehydrated hydrogels. Both methods improved EV stability over 7 days at 37 °C compared to free EVs. The pre-loading approach was ultimately selected due to its ability to give rapid <em>in situ</em> gelation within one minute. Controlled <em>in vitro</em> release of EVs from the pre-loaded hydrogels was observed to extend beyond 7 days, as determined by CD9 ELISA. The released EVs maintained their bioactivity, as evidenced by effective internalisation into ARPE-19 and H9c2 cell lines, with performance comparable to fresh EVs. The EV release profile could be varied by modifying the hydrogel concentration. These findings underscore the potential of HA-TA hydrogels for localised, sustained, EV delivery with preserved functionality.</div></div>","PeriodicalId":14187,"journal":{"name":"International Journal of Pharmaceutics","volume":"677 ","pages":"Article 125650"},"PeriodicalIF":5.3,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918376","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}

The current investigation explores the potential of glucosamine sulphate endorsed ibuprofen nanocrystals loaded polymeric gel (IBU-GS-NCs gel) for its anti-inflammatory and disease-modifying capabilities in the osteoarthritic rat model. IBU-GS-NCs were engineered by using the anti-solvent precipitation method that later exhibited particle size 34.57 ± 0.79 nm, zeta (ζ) potential −2.81 ± 0.6 mV, and drug content 7.05 ± 0.19 %. On the other hand, IBU-GS-NCs gel demonstrated 0.507 ± 0.029 % drug loading with spreadability and viscosity close to marketed diclofenac emulgel. Next, the amount of IBU infused through the rat skin in <em>ex vivo</em> permeation study from IBU-GS-NCs gel and IBU gel was calculated to be 479.59 ± 6.28 µg/cm<sup>2</sup> and 255.91 ± 4.44 µg/cm<sup>2</sup>, respectively after 24 h with 1.87-fold increment.

In contrast to the positive control, the representative radiograph for IBU-GS-NCs gel-treated osteoarthritic rats indicated regeneration of articular cartilage with the absence of osteophytes. Histological evaluation of IBU-GS-NCs gel illustrated marked recovery in articulate cartilage thickness as well as glycosaminoglycan (GAG) level. Western blot analysis for synovial tissue of positive control displayed a 9.01, 2.66, 2.51 and 5.75-fold increase in COX-2, TNF-α, and IL-1β, Col2a1 respectively as compared to normal control.

Liposomes, spherical lipid vesicles consisting of bilayer phospholipids, enable better drug delivery by preserving encapsulated pharmaceuticals and enabling tailored administration to tumor areas. In comparison to traditional doxorubicin, PLD has a better pharmacokinetic profile and less cardiotoxicity, according to the analysis, which examines several trials showing its effectiveness in treating both platinum-sensitive and platinum-resistant ovarian cancer.
