[3MS-09]【J】Diversity and Universality of Phagocytosis: The Invisible Force Shaping Life

Fri. Dec 5, 2025 11:15 AM - 12:35 PM JST
Fri. Dec 5, 2025 2:15 AM - 3:35 AM UTC
Room 9(Pacifico Yokohama Conference Center 4F, 411+412)
Organizer: Kumiko Tsukui (National Institute of Infectious Diseases), Ryuta Koyama (National Center of Neurology and Psychiatry)
Phagocytosis is a fundamental biological phenomenon observed across various species and cell types, yet many aspects of its mechanisms remain unexplored. While its crucial role in immune regulation is well established, phagocytosis also plays significant roles in neural regulation, organismal development, cancer, infection, predation, and symbiotic interactions in natural environments. This mini-symposium will highlight the involvement of phagocytosis in biological processes that have not traditionally been associated with it, demonstrating its impact across diverse research fields. By integrating insights from different disciplines, we aim to provide a novel perspective on the dynamic nature of life.
