Summary: To improve the efficiency of cancer vaccines, personalized cancer vaccines and effective delivery systems are required. In this study, personalized cancer cell membranes (CCMs) were prepared from surgically harvested cancer tissues and used as tumor-associated antigens (TAAs). The personalized CCMs were then coated onto nanoparticles loaded with imiquimod (R837) to efficiently deliver them to draining lymph nodes and elicit enhanced antitumor immune responses. When combined with programmed cell death-1 antibodies, the coated nanoparticles exhibited high efficiency against tumor progression. Therefore, personalized CCM-coated nanoparticles represent a promising cancer vaccine with significant potential for cancer immunotherapy.

Summary: A novel tumor vaccine delivery strategy using a biodegradable microneedle patch has been developed, which allows sustained release of tumor antigen and induces long term anti-tumor response. Incorporating mesoporous silica nanoparticles as a vaccine adjuvant enhances DC function and increases OVA presentation on DCs. This vaccine platform shows potential in tumor therapy with enhanced therapeutic effect and long term immune memory.

Summary: Nanoparticle-based mRNA cancer vaccines show great promise for personalized cancer treatments. We developed a bioreducible lipophilic poly(beta-amino ester) nanocarrier that can efficiently deliver multiple antigen-encoding mRNAs and nucleic acid-based adjuvants to dendritic cells. The engineered nanocarrier facilitated targeted delivery without the need for surface functionalization and resulted in robust CD8+ T cell responses and efficient antitumor therapy in murine melanoma and colon adenocarcinoma models.

Summary: Cancer vaccines are a promising strategy for preventing cancer progression through activating antitumor immunity. However, their clinical application is limited by systemic toxicity and low immunogenicity. To overcome these limitations, researchers are exploring the use of biomaterials as immune adjuvants in cancer vaccines to enhance immunogenicity and antigen presentation.

Summary: One major obstacle in cancer treatment is the presence of cancer stem cells (CSCs), which are resistant to traditional therapies and contribute to metastasis and relapse. In this study, a therapeutic vaccine targeting CSCs in melanoma was developed and shown to effectively reduce tumor growth and improve survival. The vaccine stimulated strong T cell responses against CSC-associated antigens and promoted infiltration of CD8+ T cells into tumors, while reducing the frequency of CSCs. This approach represents a safe and cost-effective strategy for targeting and eliminating CSCs in melanoma and other types of cancer.

Summary: Fas ligand (FasL) expressed on activated cytotoxic T lymphocytes (CTLs) binds to the cell surface receptor Fas, initiating a variety of signaling pathways and resulting in anti-tumor effects. Research has shown that Fas is crucial for the efficacy of CAR-T cell immunotherapy. Restoring Fas expression in tumor cells can overcome resistance to T cell cytotoxicity in human melanoma.

Summary: Rose Bengal (RB) is a fluorescent dye used in biomedical applications, especially in dermatology. Advanced delivery systems have been developed to enhance its permeation across the skin. However, there is currently no validated method for quantitatively analyzing RB in the skin. This study proposes fluorescence-based techniques and describes the development and validation of a fluorescence-coupled HPLC method to quantify RB in the skin matrix for the first time. Qualitative analysis using multiphoton microscopy and fluorescence emission spectra provides additional insight into RB's distribution and behavior in different environments.

Summary: Current procedures for transdermal drug delivery have limitations in administering nucleic acid and small or large drug molecules, and causing pain and stress for needle phobic individuals. The development of a painless micro-sized device for efficient drug delivery is still needed. Recent advances in 3D printing have made it possible to fabricate metallic microneedle arrays, which have the potential to overcome the limitations of traditional systems. This review summarizes the types and modes of drug delivery of microneedles in transdermal drug delivery, discusses their applications in the treatment of diseases, and explores the fabrication techniques and geometrical characteristics of solid metallic microneedles.

Summary: This study aimed to develop dissolving microneedles (DMN) containing ketoprofen-loaded nanosuspension (NS) and co-grinding (CG) formulations. The most promising formulations for transdermal delivery of ketoprofen were F5-MN-NS (PVA 5%-PVP 10%) and F11-MN-CG (PVA 7.5%-PVP 15%). These findings suggest that the combination of DMN with nanosuspension or a co-grinding system can effectively enhance the transdermal delivery of ketoprofen.

Summary: Bone-related injuries and diseases are a common cause of morbidity worldwide. This study demonstrates the potential of using microRNA (miRNA) gene therapy, specifically miR-26a, for bone healing. The researchers found that delivering miR-26a using the peptide RALA was effective in regulating osteogenic signaling in mesenchymal stem cells. They also showed that treating critical bone defects with RALA/miR-26a nanoparticles resulted in increased bone volume, density, and blood vessel formation. These findings highlight the utility of miRNA gene therapy in promoting bone healing, calling for further investigation in in vivo models.

Summary: Lipid nanoparticles (LNP) have played a crucial role in the success of mRNA vaccines and have opened up new opportunities for therapeutics. This study investigated the use of RALA-SME nanoparticles, which contained a blend of Spike, Membrane, and Envelope antigens, for immunization. The results showed that RALA-SME induced a robust immune response, with highly significant antigen-specific antibodies and T-cell response. Immunization with RALA-SME derivatives in Syrian Golden hamsters resulted in the production of functional antibodies capable of neutralizing SARS-CoV-2 from different lineages, providing protection against disease.
