The application of antigens and adjuvants to efficiently target antigen presenting cells (APCs) is paramount for the development of efficient vaccines. In our previous study, we showed that splenic marginal zone-B (MZ-B) cells are promising APCs in addition to dendritic cells (DCs). In this study we achieved the targeted delivery of sufficient antigen to MZ-B cells by utilizing an intravenous (IV) immunization system we originally developed. This system involves the sequential injection of empty PEGylated liposomes (PEG-Lip) and antigen-containing PEG-Lip within a prescribed interval. Herein, we describe the application of this IV immunization system as a COVID-19 vaccine to induce specific antibodies against SARS-CoV-2. To establish efficacy, SARS-CoV-2 spike proteins were used as an antigen, and α-galactosylceramide (GC) was used as an adjuvant in this study. Three days after priming with empty PEG-Lip, we injected PEG-Lip containing spike protein and α-GC. Our IV immunization system successfully induced higher levels of anti-spike antibodies when spike protein derived from HEK-293, but not E. coli., was injected into mice. The levels were less produced using conventional immunization via subcutaneous (s.c.) injections of complete Freund's adjuvant without priming. Interestingly, a lower dose (0.2 µg) of spike protein antigen encapsulated into PEG-Lip induced a higher level of anti-spike antibodies than that produced using a significantly higher dose (5 µg). The induced anti-spike antibodies inhibited the interaction between the receptor binding domain of the spike protein and the angiotensin-converting enzyme 2. This indicates that the induced antibodies tend to neutralize SARS-CoV-2. Collectively, the specific delivery of spike proteins to spleen, probably MZ-B cells, via nano-carriers could be a promising approach for the development of global pandemic vaccines that require only minimum dosages of antigen.</div></div>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":"114 3","pages":"Pages 1615-1624"},"PeriodicalIF":3.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143074862","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}

Colloidal-level dispersions of immune globulin were achieved by suspending a spray dried solid powder of protein in a protein solution made saturated by the addition of pharmaceutical excipients. The spray drying process was used to generate ∼90 % of particles below 20μ. The monomer and aggregates content of immunoglobulin were found to be 93 % and 0.3 %, respectively. The injection forces for the colloidal suspensions were characterized using a dynamic compression test. The concentrations of 300, 380, and 400 mg/mL formulations were injected at 3.8 N, 10 N, and 16.5 N of maximum injection forces, respectively, when a 24-gauge needle was used. The viscosity of a 300 mg/mL suspension was 128 cP. The viscosity of a 380 mg/mL suspension was 284 cP, and the viscosity was higher for the 400 mg/mL formulation; however, injectability was not an issue, which remains rare for non-Newtonian, shear-thickening systems. It is acknowledged that the 400 mg/mL suspension formulation remained relatively challenging as compared to other suspensions for injection because of its very high viscosity, and significant force was required to inject it. We show that where ultra-high-concentration immune globulin is being developed within reasonable constraints of pharmaceutical regulation, with an injectability parameter, formulations might make their way to the clinic when viscosity could say otherwise. However, further work should be conducted to assess chemical stability (using methods such as mass spectrometry) along with forced degradation studies prior any clinical use.</div></div>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":"114 3","pages":"Pages 1605-1614"},"PeriodicalIF":3.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143255566","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}

First, ring opening polymerization of L-lactide or L-lactide/glycolide mixture was performed in the presence of poly(ethylene glycol) (PEG) to yield PEG-PLA or PEG-PLGA block copolymers. Vancomycin was loaded in PEG-PLA or PEG-PLGA NPs using double emulsion method. Drug-loaded NPs were then encapsulated in the CMCS hydrogel. Drug release from NPs, CMCS hydrogel and hybrid NPs-hydrogel systems was performed, and release kinetics were analyzed using Korsmeyer-Peppas model. The established hybrid system exhibited prolonged drug release without burst release. Finally, the biocompatibility of the hybrid system was evidenced by the MTT, hemolysis, dynamic clotting time, and zebrafish embryotoxicity tests.
