Targeted Sodium Acetate Liposomes for Hepatocytes and Kupffer Cells: An Oral Dual-Targeted Therapeutic Approach for Non-Alcoholic Fatty Liver Disease Alleviation. Nutrients 2025; 17:930. [PMID: 40077800 PMCID: PMC11901740 DOI: 10.3390/nu17050930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2025] [Revised: 02/28/2025] [Accepted: 03/05/2025] [Indexed: 03/14/2025] Open
Abstract
Background/Objectives: Sodium acetate (NaA) has demonstrated potential in improving non-alcoholic fatty liver disease (NAFLD) by targeting hepatocytes and Kupffer cells. However, its clinical application is hindered by low oral bioavailability and insufficient liver concentrations. Liposomes, with their capacity to encapsulate water-soluble drugs and be surface-modified, offer a promising solution for targeted oral drug delivery. Methods: We designed NaA-loaded liposomes modified with sodium cholate (SC) and mannose (MAN) (NaA@SC/MAN-LPs) to target hepatocytes and Kupffer cells. Results: The NaA@SC/MAN-LPs had a mean diameter of approximately 100 nm with a positive surface charge. Compared to free NaA, NaA@SC/MAN-LPs significantly extended the serum half-life from 2.85 h to 15.58 h, substantially improving in vivo bioavailability. In vivo distribution studies revealed that NaA@SC/MAN-LPs extended the acetate peak time in the liver from 15 min to 60 min and increased hepatic acetate accumulation to 3.75 times that of free NaA. In in vitro cell experiments, NaA@SC/MAN-LPs significantly reduced the lipid droplet, triglycerides (TG), and total cholesterol (TC) in a fatty acid-induced hepatocyte steatosis model and suppressed proinflammation in a lipopolysaccharide (LPS)-activated Kupffer cell inflammation model. Free NaA effectively improved hepatic lipid deposition in NAFLD mice. Furthermore, NaA@SC/MAN-LPs decreased hepatic TG, TC, and the relative area of lipid droplets by 30.44%, 15.26%, and 55.83%, compared to free NaA. Furthermore, the liposomes reduced macrophage infiltration and pro-inflammatory response. Conclusions: The NaA@SC/MAN-LPs demonstrated effective dual targeting effects on hepatocytes and Kupffer cells, significantly improving the pathogenesis of NAFLD, compared to free NaA. This study provides a new strategy for developing effective and safe oral drugs for NAFLD.

[PMID: 37482608 PMCID: PMC10364424 DOI: 10.1186/s12951-023-01989-x] [Citation(s) in RCA: 23] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 07/08/2023] [Indexed: 07/25/2023] Open
Abstract
Therapeutic tumor vaccines have attracted considerable attention in the past decade; they can induce tumor regression, eradicate minimal residual disease, establish lasting immune memory and avoid non-specific and adverse side effects. However, the challenge in the field of therapeutic tumor vaccines is ensuring the delivery of immune components to the lymph nodes (LNs) to activate immune cells. The clinical response rate of traditional therapeutic tumor vaccines falls short of expectations due to inadequate lymph node delivery. With the rapid development of nanotechnology, a large number of nanoplatform-based LN-targeting nanovaccines have been exploited for optimizing tumor immunotherapies. In addition, some nanovaccines possess non-invasive visualization performance, which is benefit for understanding the kinetics of nanovaccine exposure in LNs. Herein, we present the parameters of nanoplatforms, such as size, surface modification, shape, and deformability, which affect the LN-targeting functions of nanovaccines. The recent advances in nanoplatforms with different components promoting LN-targeting are also summarized. Furthermore, emerging LNs-targeting nanoplatform-mediated imaging strategies to both improve targeting performance and enhance the quality of LN imaging are discussed. Finally, we summarize the prospects and challenges of nanoplatform-based LN-targeting and /or imaging strategies, which optimize the clinical efficacy of nanovaccines in tumor immunotherapies.

Abstract
In this review, we discuss recent developments in multicompartment systems commonly referred to as vesosomes, as well as their method of preparation, surface modifications, and clinical potential. Vesosomal systems are able to entrap more than one drug moiety and can be customized for site-specific delivery. We focus in particular on the possible reticuloendothelial system (RES) - mediated accumulation of vesosomes, and their application in tumor targeting, as areas for further investigation.

Surface engineering of nanomaterials with phospholipid-polyethylene glycol-derived functional conjugates for molecular imaging and targeted therapy. Biomaterials 2019; 230:119646. [PMID: 31787335 DOI: 10.1016/j.biomaterials.2019.119646] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 11/16/2019] [Accepted: 11/21/2019] [Indexed: 12/12/2022]
Abstract
In recent years, phospholipid-polyethylene glycol-derived functional conjugates have been widely employed to decorate different nanomaterials, due to their excellent biocompatibility, long blood circulation characteristics, and specific targeting capability. Numerous in vivo studies have demonstrated that nanomedicines peripherally engineered with phospholipid-polyethylene glycol-derived functional conjugates show significantly increased selective and efficient internalization by target cells/tissues. Targeting moieties including small-molecule ligands, peptides, proteins, and antibodies are generally conjugated onto PEGylated phospholipids to decorate liposomes, micelles, hybrid nanoparticles, nanocomplexes, and nanoemulsions for targeted delivery of diagnostic and therapeutic agents to diseased sites. In this review, the synthesis methods of phospholipid-polyethylene glycol-derived functional conjugates, biophysicochemical properties of nanomedicines decorated with these conjugates, factors dominating their targeting efficiency, as well as their applications for in vivo molecular imaging and targeted therapy were summarized and discussed.
