Immune Response Dynamics

HOME > People > Immune Response Dynamics

It has long been proposed that various aspects of immune responses are influenced by nervous system activity. However, little is known about how the inputs from the nervous system control the immune system. Therefore, we have been studying the cellular and molecular basis for the neural regulation of immunity. We have demonstrated that adrenergic nerves control lymphocyte trafficking through lymph nodes. Neural inputs to lymphocyte β2-adrenergic receptors enhance signals through chemokine receptors CCR7 and CXCR4, and consequently inhibit lymphocyte egress from lymph nodes (J. Exp. Med. 2014). Moreover, this mechanism contributes to diurnal variations of adaptive immune responses (J. Exp. Med. 2016). At this moment, however, the molecular basis for the crosstalk between β2-adrenergic receptors and chemokine receptors is unclear. Additionally, the real picture of the interactions between adrenergic nerves and lymphocytes remains to be visualized. We are going to address these questions in our future studies, and move forward to comprehensive understanding of immune regulation by the nervous system.
