| Research Abstract |
This research project partially elucidated the mechanisms of pathogen recognitions and early immune responses against recognized pathogens in marine bivalves. Briefly, a marine bivalves, Pacific oyster, possesses various pathogen recognition receptor (PRR) proteins, and starts immune reactions after PRR recognize pathogens. Similar defense manners have been reported from other invertebrates, but some PRR proteins in Pacific oyster have highly characteristic structures. Based on these findings, it is considered that recognition and early immune response in marine bivalves may be similar but not identical to known mechanisms in other invertebrates such as arthropods.
