Abstract
Defects in the genome cause genetic diseases and can be treated with gene therapy. Due to the limitations encountered in gene delivery, lipid-based supramolecular colloidal materials have emerged as promising gene carrier systems. In their non-functionalized form, lipid nanoparticles often demonstrate lower transgene expression efficiency, leading to suboptimal therapeutic outcomes, specifically through reduced percentages of cells expressing the transgene. Due to chemically active substituents, the engineering of delivery systems for genetic drugs with specific chemical ligands steps forward as an innovative strategy to tackle the drawbacks and enhance their therapeutic efficacy. Despite intense investigations into functionalization strategies, the clinical outcome of such therapies still needs to be improved. Here, we highlight and comprehensively review engineering aspects for functionalizing lipid-based delivery systems and their therapeutic efficacy for developing novel genetic cargoes to provide a full snapshot of the translation from the bench to the clinics. We outline existing challenges in the delivery and internalization processes and narrate recent advances in the functionalization of lipid-based delivery systems for nucleic acids to enhance their therapeutic efficacy and safety. Moreover, we address clinical trials using these vectors to expand their clinical use and principal safety concerns.

Abstract
Covalent attachment of methoxy poly(ethylene) glycol (mPEG) to therapeutic molecules is widely employed to improve their systemic circulation time and therapeutic efficacy. mPEG, however, can induce anti-PEG antibodies that negatively impact drug therapeutic effects. However, the underlying mechanism for specific binding of antibodies to mPEG remains unclear. Here, we determined the first co-crystal structure of the humanized 15-2b anti-mPEG antibody in complex with mPEG, which possesses a deep pocket in the antigen-binding site to accommodate the mPEG polymer. Structural and mutational analyses revealed that mPEG binds to h15-2b via Van der Waals and hydrogen bond interactions, whereas the methoxy group of mPEG is stabilized in a hydrophobic environment between the VH:VL interface. Replacement of the heavy chain hydrophobic V37 residue with a neutral polar serine or threonine residue offers additional hydrogen bond interactions with methoxyl and hydroxyl groups, resulting in cross-reactivity to mPEG and OH-PEG. Our findings provide insights into understanding mPEG-binding specificity and antigenicity of anti-mPEG antibodies.

Abstract
Antibody-based cancer therapy, one of the most significant therapeutic strategies, has achieved considerable success and progress over the past decades. Nevertheless, obstacles including limited tumor penetration, short circulation half-lives, undesired immunogenicity, and off-target side effects remain to be overcome for the antibody-based cancer treatment. Owing to the rapid development of nanotechnology, antibody-containing nanomedicines that have been extensively explored to overcome these obstacles have already demonstrated enhanced anticancer efficacy and clinical translation potential. This review intends to offer an overview of the advancements of antibody-incorporated nanoparticulate systems in cancer treatment, together with the nontrivial challenges faced by these next-generation nanomedicines. Diverse strategies of antibody immobilization, formats of antibodies, types of cancer-associated antigens, and anticancer mechanisms of antibody-containing nanomedicines are provided and discussed in this review, with an emphasis on the latest applications. The current limitations and future research directions on antibody-containing nanomedicines are also discussed from different perspectives to provide new insights into the construction of anticancer nanomedicines.

Abstract
Polyethylene glycol (PEG) is a flexible, hydrophilic simple polymer that is physically attached to peptides, proteins, nucleic acids, liposomes, and nanoparticles to reduce renal clearance, block antibody and protein binding sites, and enhance the half-life and efficacy of therapeutic molecules. Some naïve individuals have pre-existing antibodies that can bind to PEG, and some PEG-modified compounds induce additional antibodies against PEG, which can adversely impact drug efficacy and safety. Here we provide a framework to better understand PEG immunogenicity and how antibodies against PEG affect pegylated drug and nanoparticles. Analysis of published studies reveals rules for predicting accelerated blood clearance of pegylated medicine and therapeutic liposomes. Experimental studies of anti-PEG antibody binding to different forms, sizes, and immobilization states of PEG are also provided. The widespread use of SARS-CoV-2 RNA vaccines that incorporate PEG in lipid nanoparticles make understanding possible effects of anti-PEG antibodies on pegylated medicines even more critical.

Abstract
OBJECTIVE The aim of this study was to formulate fluorescent-labeled targeted immunoliposome to visualize the delivery and distribution of drugs in real-time. METHODS In this study, fluorescent-labeled liposomes were decorated with anti-HER2 VHH or Herceptin to improve the monitoring of intracellular drug delivery and tumor cell tracking with minimal side effects. The conjugation efficiency of antibodies was analyzed by SDS-PAGE silver staining. In addition, the physicochemical characterization of liposomes was performed using DLS and TEM. Finally, confocal microscopy visualized nanoparticles in the target cells. RESULTS Quantitative and qualitative methods characterized the intracellular uptake of 110±10 nm particles with near 70% conjugation efficiency. In addition, live-cell trafficking during hours of incubation was monitored by wide-field microscopy imaging. The results show that the fluorescent-labeled nanoparticles can specifically bind to HER2-positive breast cancer with minimal off-target delivery. CONCLUSION This kind of nanoparticles can have several applications in personalized medicine, especially drug delivery and real-time visualization of cancer therapy. Moreover, this method also can be applied in the targeted delivery of contrast agents in imaging and thermotherapy.

Abstract
PURPOSE This study was aimed at developing the trispecific antibodies (anti-EGFR/anti-FAP/anti-mPEG, TsAb) or dual bispecific antibodies (anti-EGFR/anti-mPEG and anti-FAP/anti-mPEG) docetaxel (DTX)-loaded mPEGylated lecithin-stabilized micelles (mPEG-lsbPMs) for improving the targeting efficiency and therapeutic efficacy. METHODS mPEG-lsbPMs were simply prepared via thin film method. The trispecific antibodies or bispecific antibodies bound the mPEG-lsbPMs by anti-mPEG Fab fragment. The formulations were characterized by DLS and TEM; in vitro and in vivo studies were also conducted to evaluate the cellular uptake, cell cytotoxicity and therapeutic efficacy. RESULTS The particle sizes of mPEG-lsbPMs with or without the antibodies were around 100 nm; the formulations showed high encapsulation efficiencies of 97.12%. The TsAb and dual bispecific antibodies were fabricated and demonstrated their targeting ability. Two EGFR-overexpressed cell lines (HT-29 and MIA PaCa-2) were co-cultured with FAP-overexpressed WS1 cells (HT-29/WS1; MIA PaCa-2/WS1) to mimic a tumor coexisting in the tumor microenvironment. Cellular binding study revealed that the binding of anti-FAP micelles to three co-culture ratios (4:1, 1:1, and 1:4) of HT-29/EGFR to WS1/FAP was significantly higher than that for TsAb micelles and dual (1:1) micelles, and the binding of those targeting antibodies to WS1/FAP and MIA PaCa-2/EGFR was equally efficacious resulting in a similar binding amount of the TsAb and dual BsAbs (1:1) with the co-culture of MIA PaCa-2/EGFR and WS1/FAP at a 1:1 ratio. Antitumor efficacy study showed that treatment with DTX-loaded mPEG-lsbPMs modified with or without BsAbs, dual BsAbs (1:1), and TsAbs was enhanced in inhibiting tumor growth compared with that for Tynen® while showing fewer signs of adverse effects. CONCLUSION Active targeting of both tumors and TAF-specific antigens was able to increase the affinity of DTX-loaded mPEG-lsbPMs toward tumor cells and TAFs leading to successive uptake by tumor cells or TAFs which enhanced their chemotherapeutic efficacy against antigen-positive cancer cells.

Abstract
A vast range of biomedical applications relies on the specificity of interactions between an antigen and its cognate receptor or antibody. This specificity can be highest when said antigen is a non-natural (synthetic) molecule introduced into a biological setting as a bio-orthogonal ligand. This review aims to present the development of this methodology from the early discovery of haptens a century ago to the recent clinical trials. We discuss such methodologies as antibody recruitment, artificial internalizing receptors and chemically induced dimerization, present the use of chimeric receptors and/or bispecific antibodies to achieve drug targeting and transcytosis, and illustrate how these platforms most impressively found use in the engineering of therapeutic cells such as the chimeric antigen receptor cells. This review aims to be of interest to a broad scientific audience and to spur the development of synthetic artificial ligands for biomedical applications.
