Enhancing cross-protections against diverse influenza viruses is desired for vaccinations. Neuraminidase (NA)-specific antibody responses have been found to independently correlate with a broader protection spectrum. Here, we report sequential immunization regimen that includes priming NA protein followed by boosting peptide nanoclusters, which targeted enhancement of in BALB/c mice certain cross-protective B-cell epitopes was achieved. The nanoclusters were fabricated via desolvation absolute ethanol and only composed composite peptides. Unlike KLH conjugates, would not induce influenza-unrelated immunity. We the incorporation hemagglutinin H2-d class II restriction into peptides could be beneficial enhancing peptide-specific response. Of note, boosters N2 induced stronger serum cross-reactivities heterologous even heterosubtypic N7 N9 than triple immunizations prototype recombinant tetrameric (rt) N2. mouse challenge experiments HK68 H3N2 also demonstrated strong effectiveness nanocluster conferring protection.

Abstract Nanocatalytic platforms are promising in cancer therapeutics via combining multiple treatments, which can be leveraged through the metabolic dysfunction progression. However, lack of effective tumor delivery hampers this approach. Here, a gelatin‐based platform is designed that preloaded with gold nanoparticles and photothermal polypyrrole (GNPs@AuNPs‐PPy) an acid‐induced doping enhancement. Benefiting from associated overexpression H 2 O , peroxidase‐like Au induce burst oxidative reactive oxygen species local microenvironment (TME). Subsequent orchestration redox surroundings recruits immune cells, showcasing antineoplastic pathway. Under near infrared light (NIR) irradiation, nanohybrids exhibit dual pH/NIR enhanced drug release within TME, while allowing for multimodal imaging‐guided theranostics. Leveraging modality, GNPs@AuNPs‐PPy delivers quercetin (a natural antitumor mediator) boosting anti‐tumor therapy. The gelatin‐mediated nanomedicine provides alternative combinatorial dynamic treatment.

Fungal infections represent a significant global health challenge. Candida albicans is particularly widespread pathogen, with both molecular and biofilm-based mechanisms making it resistant to or tolerant of available antifungal drugs. This study reports combination therapy, active against C. albicans, utilizing terbinafine essential oils incorporated into gelatin-based nanoemulsion system (T-GNE). Eugenol methyl eugenol/terbinafine T-GNEs had an additive efficacy, while carvacrol (CT-GNE) worked synergistically terbinafine, providing effective treatment minimal mammalian cell toxicity. Confocal microscopy demonstrated that CT-GNE penetrated the dense biofilm disrupted fungal membrane. Overall, in GNE provided promising for biofilms.
