| Outline of Final Research Achievements |
Exosomes are gaining attention as new intercellular communication systems.Exosomes are present in the saliva; miRNA in the exosomes are used in cancer diagnosis. Although saliva collection is noninvasive, its practical application as a diagnostic material is limited. Furthermore, it is more difficult to extract exosomes with stable physicochemical properties from saliva than from other body fluids. To study the salivary exosomes, we extracted and evaluated salivary exosome proteins from subjects of two age groups. The climacteric exosomes contained major salivary proteins, including immunoglobulins or amylase, whereas the adolescent exosomes contained keratins, ribosomal proteins, ATP synthase, etc. These results suggest that several proteins could be identified in the fundamental salivary exosome.
