Summary: IgG antibodies have an under-recognized effector function of trapping pathogens in mucus at mucosal surfaces, preventing them from contacting target cells and facilitating rapid elimination. This function, revealed in the past decade, is a universal effector of IgG-Fc capable of immobilizing various types of pathogens.

Summary: Nanoscale formulations can enhance the efficacy of cancer vaccines by combating the immunosuppressive nature of the tumor microenvironment. A newly synthesized nanoparticulate formulation demonstrated adjuvant properties in vivo, leading to increased TAA-specific T cells, reduced tumor burden, protection against tumor rechallenge, and improved median survival in tumor-challenged mice.

Summary: The study demonstrated that the spliceosome inhibitor IP2 can enhance antigen presentation, activate CD8(+) T cell response, and inhibit tumor growth by modifying the antigen repertoire displayed on MHC-I molecules in cancer cells. Combination of IP2 with a peptide vaccine targeting a specific epitope showed a synergistic antitumor effect.

Summary: Infectious diseases of the respiratory tract are a major cause of global morbidity and mortality. Delivering vaccines through the respiratory mucosal route shows promise in combating respiratory infections. Through a study using mice, we found that compared to intranasal delivery, endotracheal delivery resulted in a deeper and wider distribution of the vaccine in the lungs, leading to improved immunogenicity and protection against the target pathogen. Our findings support the further development of inhaled aerosol delivery of vaccines over intranasal delivery for human use.

Summary: Cladribine-treated MS patients can mount an adequate immune response to influenza independently of treatment duration and time interval to the last cladribine administration. The antibody response against influenza A was comparable between cladribine-treated patients and controls, while the response against influenza B was lower in the cladribine cohort. The increase in geometric mean titers was also lower in the cladribine group compared to controls, but titers increased in both groups for all strains.

Summary: The study aimed to produce PEG-coated nanoparticles with mucus-permeating properties for oral drug delivery using simple procedures and regulatory-approved compounds. The nanoparticles were successfully coated with PEG 35,000, reducing their hydrophobic surface and increasing their hydrophilicity. This coating allowed the nanoparticles to have increased mobility in mucus, potentially enhancing the oral bioavailability of biomacromolecules and other biologically active compounds.

Summary: This study investigates the potential of micelles composed of polylactide-block-poly(N-acryloxysuccinimide-co-N-vinylpyrrolidone) as a delivery system for vaccines. The micelles were non-toxic and efficiently taken up by immune cells. Coupling of antigenic protein p24 on the micelles improved its antigenicity. In mouse immunization, the micelles showed comparable immune response intensity to gold standards and higher avidity index over time.

Summary: Polyethylene glycol (PEG) is commonly found in nanomedicines and pharmaceuticals, and recent studies have shown that anti-PEG antibodies are present in a significant portion of the human population. Understanding the mechanisms behind the immune response to PEG is crucial, as these antibodies can impact the efficacy of PEGylated therapeutics. This study investigates the immune response to polymeric nanoparticles administered through different routes, and the results suggest that the mechanisms involved vary depending on the administration route. Knowledge of these mechanisms can be utilised to design nanomedicines that engage the immune system in specific ways.

Summary: A simple strategy has been developed to convert whole-cell vaccines into nanoscale size to promote their lymphatic migration and intracellular antigen presentation, aiming to enhance immune responses. The universal carrier-free nano-vaccine fabricated through a two-step vortex-sonification method based on alum-induced and cancer/bacterial cell membrane coated protein antigen nanoparticles can efficiently migrate to lymph nodes after subcutaneous vaccination, where they are taken up by APCs for antigen presentation and activation of immune processes.

Summary: Exosomes, as endogenous courier vesicles, have gained increasing attention as biomimetic drug delivery vehicles. In this study, insulin-loaded milk-derived exosomes were fabricated and demonstrated to exhibit superior hypoglycemic effects when orally administered, compared with subcutaneously injected insulin. Mechanism studies revealed the multi-functional properties of milk-derived exosomes, including active multi-targeting uptake, pH adaptation, signal pathway activation, and mucus penetration, which contribute to their excellent oral performance.
