Prof. Denis Leclerc has identified particles produced from the nucleocapsid protein of the papaya mosaic virus (PapMV), which have surprising immunological properties. These particles can, among other things, enhance the immune response of seasonal flu vaccines.
Studies carried out have shown that these particles:
- unlike classic adjuvants, not only stimulate the antibody response but cellular response as well;
- can potentially be used in immunotherapy (cancer treatment);
- have no apparent side effects, even in high doses;
- are particularly stable (long-term preservation of vaccines).
