RIKEN Center for Integrative Medical Sciences Laboratory for Immune Cell Systems
Team Leader: Shigeo Koyasu (D.Sci.)
The immune system plays a critical role in not only host defense against invading microbesbut also the maintenance of homeostasis in our bodies by interacting with neuronal system and metabolism. We previously identified a new lymphoid tissue in mouse and human mesentery that we termed fat-associated lymphoid cluster (FALC). We discovered in the FALC a new innate lymphocyte subset that produces Th2 cytokines and named this new lymphocyte "Natural Helper (NH) Cell", which is now called group 2 innate lymphoid cells (ILC2). Adipose tissues contain several immune cell types including NH cells, macrophages and regulatory T cells (Treg). Inflammation in adipose tissue leads to insulin resistance and eventually the onset of diabetes. We elucidate the immune cell network in adipose tissue in order to understand how immune cells and the metabolic system interact and control the homeostasis of metabolism.
