RIKEN Center for Integrative Medical Sciences Laboratory for Innate Immune Systems
Team Director: Kazuyo Moro (Ph.D.)
Research Summary

The immune system plays a critical role in the host defense against invading microbes. Immune reactions are also involved in the onset and pathophysiology of many diseases including allergic and autoimmune diseases. We currently focus on an innate lymphocyte population that we identified. We have identified a new lymphoid tissue in mouse and human mesentery and termed this tissue fat-associated lymphoid cluster (FALC). We discovered in the FALC a new innate lymphocyte subset producing of Th2 cytokines and named this new lymphocyte "Natural Helper (NH) Cell". NH cells which are classified to group 2 Innate lymphoid cells (ILC2) support the proliferation of B1 cells in the peritoneal cavity and induce goblet cell hyperplasia during the innate phase of nematode infection. ILC2 also play a role in allergic diseases. We aim to understand the role of ILC2 in our immune system.
