Their unique characteristics enable the development of more effective delivery systems. However, the behavior of liposomes <em>in vivo</em> differs significantly from their <em>in vitro</em> performance, which can impact their clinical application. Upon systemic administration, liposomes must circulate in the body for extended periods to reach target tissues. A challenge arises when liposomes encounter biological fluids <em>in vivo</em>, where proteins and other biomolecules form a \"protein corona\" around the liposomes, which can alter their function. Despite the development of stealth liposomes, completely preventing protein corona formation remains a challenge. The presence of the protein corona can interfere with interactions between targeting ligands and tissues, potentially reducing the efficacy of targeted delivery systems. Recent studies, however, suggest that the protein corona may also be utilized to enhance liposome functionality and targeting. This review explores the formation of the protein corona on liposomes, the factors influencing the structure and composition of liposome-protein corona complexes, and strategies to control this process. It also examines <em>in vivo</em> studies on protein corona formation and its impact on liposome behavior, targeting capacity, and drug release profiles. Finally, we discuss the concept of personalized liposome-protein corona complexes for the detection of disease biomarkers <em>in vivo</em>.</div></div>","PeriodicalId":12018,"journal":{"name":"European Journal of Pharmaceutical Sciences","volume":"212 ","pages":"Article 107166"},"PeriodicalIF":4.3,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144293580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the fed state, TIF contained biorelevant lipid concentrations but remained monophasic without phase separation, unlike HIF. This was likely due to higher bile salt levels (5.3 times that of HIF), which solubilized all lipids into the micellar phase.

While the oral route offers higher patient adherence, it is limited by poor mucosal transport, restricting its use to intestinal infections. To address these challenges, this study explores the encapsulation of vancomycin into archaeosomes -phospholipid-based nanocarriers incorporating archaeal lipids, which exhibit exceptional stability in the gastrointestinal environment and interact specifically with enterocytes. Previous work demonstrated that lipid nanocarrier formulations benefit from the incorporation of the archaeal lipid calditolglycerocaldarchaeol (GCTE), facilitating mucosal barrier penetration and increasing bioavailability <em>in vivo</em>. In this study, we investigated the effects of archaeal lipid extract (ALE) and purified caldarchaeol (GDGT) on the pharmacokinetics and oral bioavailability of vancomycin in male Wistar rats. Our findings reveal that archaeosomal formulations significantly increase systemic exposure by prolonging circulation time and enhancing plasma drug concentrations, combined with high biocompatibility. Notably, the oral bioavailability (as measured by the area under the curve, AUC) increased 9-fold with GDGT liposomes and 4-fold with ALE liposomes compared to free vancomycin. These results highlight the potential of archaeal lipid-based drug delivery systems to enable oral administration of therapeutics that are traditionally injection-only.</div></div>","PeriodicalId":12018,"journal":{"name":"European Journal of Pharmaceutical Sciences","volume":"212 ","pages":"Article 107159"},"PeriodicalIF":4.3,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144257706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
