| Research Abstract |
Lymph node is a crucial site for the induction of immune responses, in which stromal cells constructing elaborate network support the activity of immune cells. However, the molecular basis of stromal cell function is still unclear. In this study, we tried to identify factors expressed in stromal cells and addressed their roles in the regulation of immune cell function. As a consequence, we found that stromal cells produce a lysophosphatidic acid(LPA) synthetic enzyme, autotaxin(ATX), and ATX-LPA axis is involved in the interstitial migration of lymphocytes. Therefore, stromal cells are suggested to control the activity of lymphocytes via producing various molecular mediators.
