| Outline of Final Research Achievements |
CD72 is an inhibitory receptor expressed mostly in B lymphocytes, and contains a C-type lectin-like domain. We demonstrated that CD72 binds to various sulfated glycans and inhibits immune responses to sulfated glycans. Sulfated glycans are abundantly produced in vertebrates including human, but are not normally produced by microbes. These findings suggest that CD72 recognizes sulfated glycans as a self-associated molecular pattern, and is involved in distinction between self and microbes.
