Effect of the Protein Corona Formation on Antibody Functionalized Liquid Lipid Nanocarriers. Int J Mol Sci 2023; 24:16759. [PMID: 38069079 PMCID: PMC10706289 DOI: 10.3390/ijms242316759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 11/21/2023] [Accepted: 11/22/2023] [Indexed: 12/18/2023] Open
Abstract
The main aim of this study is to report basic knowledge on how a protein corona (PC) could affect or modify the way in which multifunctionalized nanoparticles interact with cells. With this purpose, we have firstly optimized the development of a target-specific nanocarrier by coupling a specific fluorescent antibody on the surface of functionalized lipid liquid nanocapsules (LLNCs). Thus, an anti-HER2-FITC antibody (αHER2) has been used, HER2 being a surface receptor that is overexpressed in several tumor cells. Subsequently, the in vitro formation of a PC has been developed using fetal bovine serum supplemented with human fibrinogen. Dynamic Light Scattering (DLS), Nanoparticle Tracking Analysis (NTA), Laser Doppler Electrophoresis (LDE), and Gel Chromatography techniques have been used to assure a complete physico-chemical characterization of the nano-complexes with (LLNCs-αHER2-PC) and without (LLNCs-αHER2) the surrounding PC. In addition, cellular assays were performed to study the cellular uptake and the specific cellular-nanocarrier interactions using the SKBR3 (high expression of HER2) breast cancer cell line and human dermal fibroblasts (HDFa) (healthy cell line without expression of HER2 receptors as control), showing that the SKBR3 cell line had a higher transport rate (50-fold) than HDFa at 60 min with LLNCs-αHER2. Moreover, the SKBR3 cell line incubated with LLNCs-αHER2-PC suffered a significant reduction (40%) in the uptake. These results suggest that the formation of a PC onto LLNCs does not prevent specific cell targeting, although it does have an important influence on cell uptake.

Brzeziński M, Gonciarz W, Kost B, Mikołajczyk-Chmiela M. Can histamine cause an enhancement of the cellular uptake and cytotoxicity of doxorubicin-loaded polylactide nanoparticles? Eur J Pharm Sci 2023; 185:106438. [PMID: 37001569 DOI: 10.1016/j.ejps.2023.106438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Revised: 03/28/2023] [Accepted: 03/28/2023] [Indexed: 03/31/2023]
Abstract
Histamine (His) in humans is physiologically involved in neurotransmission and increases vascular permeability during the development of inflammatory response and immunity. It could be used to enhance drug-loaded nanoparticles (NPs) distribution. However, it cannot be freely delivered due to the risk of His-dose-dependent deleterious effects. His can be attached to the polymeric backbone during polymerization to overcome this limitation. In this study, His was used as an initiator of lactide polymerization, and the obtained macromolecules were subsequently used to prepare doxorubicin (DOX)-loaded NPs by nanoprecipitation and microfluidics for examination of anti-cancer properties. Notably, the in vitro activity towards gastric cancer cells (AGS) of the NPs composed of histamine-functionalized polylactides (PLAs) was greatly enhanced compared to control NPs built from hydroxy‑functionalized PLAs. Furthermore, Zonula occludens-1 (ZO-1) tight junction protein production was significantly diminished after treating cells with DOX-loaded NPs assembled with PLAs with histamine residues. These results demonstrate the synergistic effect in cytotoxicity towards gastric cancer cells of DOX and the histamine that are carried by NPs. It is believed that His-DOX NPs strategy may lead to effective, targeted, and low-toxic delivery of drugs into cancer cells.
