科学家开发出新型mRNA疫苗平台

Core Viewpoint - A new mRNA vaccine platform developed by researchers at Yale University aims to significantly enhance immune responses and expand the application potential of mRNA vaccines in various disease prevention and treatment [1][2]. Group 1: Vaccine Technology - The new technology, named "Molecular Vaccine Platform" (MVP), addresses the issue of antigen exposure by adding a "cellular GPS" module to mRNA-encoded proteins, guiding them efficiently to the cell surface [1][2]. - The "cellular GPS" module consists of natural membrane protein elements, including signal peptides and transmembrane anchors, which ensure stable expression of proteins on the cell membrane [2]. Group 2: Experimental Results - Laboratory tests on various pathogens, including monkeypox, human papillomavirus (HPV), and varicella-zoster virus, demonstrated stronger antigen expression, higher antibody levels, and more active T-cell responses [2]. Group 3: Future Applications - Researchers are working to expand this technology to broader disease areas, including cancer, AIDS, and autoimmune diseases, aiming to transition mRNA technology from infectious disease prevention to comprehensive medical applications [2][3]. - The MVP technology is expected to accelerate the development of new vaccines, reduce research and development costs and timelines, and elevate vaccine technology to new heights [3].
