Recent progress in cancer vaccines and nanovaccines.

Biomaterials

March 2025

Wellman Center for Photomedicine and Department of Dermatology, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA. Electronic address:

Vaccine science, nanotechnology, and immunotherapy are at the forefront of cancer treatment strategies, each offering significant potential for enhancing tumor-specific immunity and establishing long-lasting immune memory to prevent tumor recurrence. Despite the promise of these personalized and precision-based anti-cancer approaches, challenges such as immunosuppression, suboptimal immune activation, and T-cell exhaustion continue to hinder their effectiveness. The limited clinical success of cancer vaccines often stems from difficulties in identifying effective antigens, efficiently targeting immune cells, lymphoid organs, and the tumor microenvironment, overcoming immune evasion, enhancing immunogenicity, and avoiding lysosomal degradation.

Molecular simulation reveals that pathogenic mutations in BTB/ANK domains of Arabidopsis thaliana NPR1 circumscribe the EDS1-mediated immune regulation.

J Plant Physiol

December 2024

Department of Life Sciences, Yeungnam University, Gyeongsan, Gyeongsangbuk-do, 38541, Republic of Korea. Electronic address:

The NPR1 (nonexpressor of pathogenesis-related genes 1) is a key regulator of the salicylic-acid-mediated immune response caused by pathogens in Arabidopsis thaliana. Mutations C150Y and H334Y in the BTB/ANK domains of NPR1 inhibit the defense response, and transcriptional co-activity with enhanced disease susceptibility 1 (EDS1) has been revealed experimentally. This study examined the conformational changes and reduced NPR1-EDS1 interaction upon mutation using a molecular dynamics simulation.
