| Outline of Final Research Achievements |
We had previously revealed a mechanism by which noradrenaline, the principal neurotransmitter released from adrenergic nerves, controls lymphocyte exit from lymph nodes. Additionally, we had found that fractions of B cells and myeloid cells are capable of producing noradrenaline. This research project aimed to clarify the role of these noradrenaline-producing immune cells in the control of lymphocyte trafficking. To this end, we generated B cell- or myeloid cell-specific knockout mice lacking the gene encoding a noradrenaline-synthesizing enzyme. However, these mutant mice showed no alterations in lymphocyte exit from lymph nodes. These observations suggest that noradrenaline derived from these immune cells makes little contribution to this aspect of the immune system.
