One of the benefits of immunotherapy for cancer is that treatments can often be tailored to address a patient’s individual needs. Scientists in Switzerland have now developed a method of modifying dendritic cell vaccines that makes them easier to personalize.

Aiding the Body’s Own Immune Response

Dendritic cell vaccines are normally created by force-feeding dendritic cells with tumor antigens. Scientists at the Swiss Institute for Experimental Cancer Research have developed a modification that allows dendritic cells to acquire antigens from a patient’s tumor.

Prof. Michele De Palma, winner of the 2017 Swiss Cancer League award, led the team of researchers in creating an extracellular vesicle (EV)-internalizing receptor, referred to as EVIR. The EVIR has been optimized to enhance dendritic cells and their ability to selectively uptake cancer cell-derived EVs.

Antigen-laden exosomes and other extracellular vesicles are released by tumors in sizable quantities. The EVIR helps dendritic cells target the exosomes more precisely and present them to killer T-cells for a more efficient immune response.

Streamlining the Job of Dendritic Cells

De Palma explained the phenomenon of cross-dressing, in which dendritic cells display the acquired antigens directly on their surface. The process simplifies the immune response by eliminating the need for more complex interactions within the dendritic cell itself.
