Beyond direct membrane effects, ACPs exert multifaceted intrace

Cancer vaccines as targeted therapies: translational advances and challenges.

Cancer vaccines represent a promising class of immunotherapeutic agents with potential applications in cancer prevention and treatment. By eliciting tumor-specific immune responses, these vaccines may offer durable protection against tumor progression, recurrence, and metastasis while minimizing off-target toxicity associated with conventional therapies. In addition, activation of adaptive immunity and the induction of immunological memory may contribute to sustained anti-tumor surveillance. Despite these advantages, clinical translation has been limited by immunological complexity, antigen se…

Design Considerations for Potent DNA-Platform-Based Cancer Vaccines.

Cancer vaccines have the potential to harness the strength of our immune system to fight cancer safely and effectively, but their potency relies on the presentation and tuned delivery of the vaccine's components.

Vaccines for cancer prevention: exploring opportunities and navigating challenges.

Improved understanding of cancer immunology has gradually brought increasing attention towards cancer-preventive vaccines as an important tool in the fight against cancer. The aim of this approach is to reduce cancer occurrence by inducing a specific immune response targeting tumours at an early stage before they can fully develop. The great advantage of preventive cancer vaccines lies in the potential to harness a less-compromised immune system in vaccine recipients before their immune responses become affected by the advanced status of the disease itself or by aggressive treatments such as c…

Clinical trials of self-replicating RNA-based cancer vaccines.

Therapeutic cancer vaccines, designed to activate immune effectors against tumor antigens, utilize a number of different platforms for antigen delivery. Among these are messenger RNAs (mRNA), successfully deployed in some prophylactic SARS-CoV2 vaccines. To enhance the immunogenicity of mRNA-delivered epitopes, self-replicating RNAs (srRNA) that markedly increase epitope expression have been developed. These vectors are derived from positive-strand RNA viruses in which the structural protein genes have been replaced with heterologous genes of interest, and the structural proteins are provided …

Live vaccines-a short-cut to cancer viro-immunotherapy.

Tumour immunotherapies have been a breakthrough in clinical oncology but only a few patients benefit from this progress. Additional interventions that sensitize immunologically cold tumours for the administration of checkpoint modifiers are urgently needed. In this issue of EMBO Molecular Medicine, Aznar et al present the already approved yellow fever vaccine 17D as an oncolytic agent for tumour immunoactivation. In tumour-bearing mice, they demonstrated a convincing synergy of the vaccine with CD137 agonistic antibodies resulting in significantly improved survival.

Re-Emergence of Dendritic Cell Vaccines for Cancer Treatment.

Dendritic cells (DCs) are essential in immunity owing to their role in activating T cells, thereby promoting antitumor responses. Tumor cell … h DC functions are disrupted by the tumor microenvironment, and highlight recent developments in DC cancer vaccines.

Cancer vaccines: a new frontier in prevention and treatment.

Vaccines have been exceptionally effective against diseases such as smallpox, measles, chickenpox, and polio. They are among the safest and most cost-effective agents for disease prevention. In recent years, vaccination has been considered for other diseases, including AIDS and cancer. Cancer vaccines can be categorized as preventive or therapeutic. Preventive vaccines, which are commercially available for cervical cancer and liver cancer, block infection with the causative agents of human papillomavirus and hepatitis B virus, respectively. The benefit of cancer treatment vaccines lies in thei…

Semi-allogeneic vaccines for patients with cancer and AIDS.

Interest in semi-allogeneic vaccines has been increasing, as demonstrated by the publication of successful preclinical and clinical studies by others and us that validate this immunotherapeutic approach to cancer and HIV-infection. We now report that lymphocytes from an HLA-A2+ melanoma patient, stimulated with a GP100-derived epitope and semi-allogeneic hybrids, lysed target cells presenting this peptide more efficiently than lymphocytes stimulated with GP100 peptide alone. Phenotypic analysis with GP100/HLA-A2 tetramer complexes also demonstrated a significant increase in the size of the GP1

Nanotechnology-Based Cancer Vaccines: Translational Barriers and Emerging Strategies.

Cancer vaccines represent a promising strategy in cancer immunotherapy by inducing tumour-specific immune responses.

Current research into novel therapeutic vaccines against cervical cancer.

Cervical cancer and cervical intraepithelial neoplasia (CIN) are well-known outcomes of a human papillomavirus (HPV) infection. Viral oncogenes expressions like E6, E7, and, recently recognized E5, lead to HPV-related malignant progression. Although HPV prevention by powerful vaccines against most frequent and oncogenic genotypes is feasible, current treatment against cervical neoplasia is distant from an ideal one. In addition, late diagnosis is commonly associated with a poor prognosis. On top of that, radiotherapy, chemotherapy, or surgery are less effective in high-grade lesions. Areas cov
