| Outline of Final Research Achievements |
Cells constituting our body communicate with each other during various aspects of biological processes. The communications have been studied mainly through secretary molecules such as cytokines and hormones, but a novel mechanism of intercellular communication, mediated through exosomes, has recently received much attention as another communication mediator. Exosomes are small vesicles secreted from various kinds of cells particularly immune cells and cancer cells, but their secretory of mechanism is still not well-elucidated. In this study, we screened molecules which is involved in exosome secretion, and then identified a motor protein myosin as the molecule. We studied about exosome secretion in cells or mice which had a mutation in myosin, and revealed that immune cells controlled inflammation by communication with each other via exosomes in microbial infection.
