The 28th annual meeting of the Japanese Association for Developmental and Comparative Immunology (JADCI)was held on August 18-20, 2016, at Tokyo Medical & Dental University, Tokyo. Seventy-one scientists including graduate students attended this meeting to discuss the host defense mechanisms of invertebrates and vertebrates. The meeting featured a special lecture and two symposia. Additionally, there were 20 general oral presentations, followed by the active discussion.
Special lecture: Dr. Kenjiro Wake(Tokyo Medical & Dental University). From the theory of the reticulo-endothelial system to natural immunity - with much attention to sinusoidal cells in the liver.
In this special lecture, the valuable studies on the phagocytosis performed by Elie Metchnikoff were first reported. Then, a series of theories on the reticulo-endothelial system (RES) were mentioned in relation to the theories advanced by Kiyono and Aschoff. Next, the mononuclear phagocytic system (MPS) introduced by van Furth was explained as an opposite theory against RES. Finally, it was re-considered that RES in the liver played an important role as the scavenger endothelial cell system, leading to a natural immunity functioning as a homeostasis.

General presentations:
Twenty oral presentations involved in the host defenses of fish, arthropods, molluscs, echinoderms and mammals were made over the 2 days.
The winner of the Award of the ' Furuta Excellent Scientific Papers' was Dr. Ryohei Furukawa at Iwate Tohoku Megabank Organization of Iwate Medical University. (Two macrophage migration factors regulate starfish larval immune cell chemotaxis.)
The winner of the Furuta Young Investigator Award was Mr.Hiroki Nagai at Tohoku University.
