| Research Abstract |
In this project, we aimed to clarify the trafficking of immune cells that are responsible for peripheral immune tolerance. We also addressed the mechanisms and immunological significance of such cellular trafficking. Following results were obtained through this project: 1) CCR7 and CXCR4 regulate the migration of nTreg into lymph node paracortex and medulla, respectively, 2) MDSC are composed of monocytic cells and neutrophils, and balance between these cell types are critically regulated by a chemokine receptor CCR2, 3) niche size of antibody-producing cells in lymph nodes are likely regulated by B-cell mediated remodeling of the niche, 4) novel mechanisms controlling DOCK2-mediated migration and activation of leukocytes were elucidated.
