Investigation into the immunogenicity of dendritic cell-derived exosomes

Funded Activity Summary

Dendritic cells are essential in immune responses. They have unique capacity to stimulate lymphocytes specific to viruses, bacteria and cancers. They are extremely rare and difficult to isolate. We have developed a method of culture which gives a continuous supply of dendritic cells. Cells produced in our culture also produce a high yield of acellular membranous particles called 'exosomes' which have been previously been very difficult to isolate and characterise. Some preliminary reports suggest that exosomes can induce or modify immune responses and that they have enormous immunotherapeutic potential. Further study of their clinical application is limited by the difficulty of isolating enough dendritic cells from which to isolate exosomes. This study will involve production and characterisation of exosomes from our unique murine dendritic cell culture system. Exosomes isolated will be assessed in terms of potential for immunotherapeutic treatment of disease such as cancer, viral infection and autoimmunity.
