Nanovaccines are able to deliver antigen(s) and immunomodulator(s) directly to antigen-presenting cells (APCs) of the lymphatic system. Positive charges improve their uptake by APCs and often drive a Th-1 biased immune response so necessary against infectious diseases caused by intracellular pathogens and cancers. However, cationic compounds often display a dose-dependent toxicity so that systematic evaluation of cytotoxicity against cells in culture is required. After the rapid evolution of nanovaccines against SARS-Covid 2, mRNA vaccines gained much strength and have been designed against several infectious diseases, often relying on cationic components for mRNA protection. Once established the limiting concentration for the cationic compound, cationic nanovaccines perform well eliciting the desired Th-1 improved immune response in most cases. Other valuable approach found in the literature has been the construction of biocompatible nanoparticles (NPs) carrying cationic lipids, polymers or surfactants so that minimization of the concentration for the cationic component led to absence of toxicity. Against cancer, recent constructions of nanovaccines in situ after cancer cell disruption in the presence of adjuvants led to systemic presentation of multiple tumoral antigens yielding, in many instances, prevention of metastasis appearance and conversion of tumors non treatable by immunotherapy into treatable ones.

The development of nanovaccines capable of eliciting tumor‐specific immune responses holds significant promise for tumor immunotherapy. However, many nanovaccine designs rely heavily on incorporating multiple adjuvants and carriers, increasing the biological hazards associated with these additional components. Here, this work introduces novel flexible nanocapsules (OVAnano) designed to mimic extracellular vesicles, primarily using the ovalbumin antigen and minimal polyethylenimine adjuvant components. These results show that the biomimetic flexible structure of OVAnano facilitates enhanced antigen uptake by dendritic cells (DCs), leading to efficient antigen and adjuvant release into the cytosol via endosomal escape, and ultimately, successful antigen cross‐presentation by DCs. Furthermore, OVAnano modulates the intracellular nuclear factor kappa‐B (NF‐κB) signaling pathway, promoting DC maturation. The highly purified antigens in OVAnano demonstrate remarkable antigen‐specific immunogenicity, triggering strong antitumor immune responses mediated by DCs. Therapeutic tumor vaccination studies have also shown that OVAnano administration effectively suppresses tumor growth in mice by inducing immune responses from CD8+ and CD4+ T cells targeting specific antigens, reducing immunosuppression by regulatory T cells, and boosting the populations of effector memory T cells. These findings underscore that the simple yet potent strategy of employing minimal flexible nanocapsules markedly enhances DC‐mediated antitumor immunotherapy, offering promising avenues for future clinical applications.
