项目摘要
PROJECT SUMMARY – ABSTRACT
This application seeks to understand how the brain, through signals delivered via sympathetic neurons,
controls immune function. The sympathetic nervous system controls a variety of cellular and metabolic
functions and plays a critical role in the flight or fight response. The adrenergic class of neurotransmitter
receptors binds to nor-epinephrine secreted by sympathetic neurons and is a target of various pharmacological
agonists and antagonists used in humans. Very little is known about how this pathway interfaces with the
immune system. We recently found selective expression of the β2-adrenergic receptor (ADRB2) on human
CD8+ memory T cells, and it is also expressed in murine CD8+ T cells. Signaling through this receptor
significantly suppressed various effector T cell functions including cytokine secretion and lytic activity. Further,
CD8+ CTLs lacking the ADRB fail to generate memory cells following infection with vesicular stomatitis virus.
Given the importance of this pathway in regulating multiple physiological processes, we wished to determine
the role of the ADRB2 in regulating the major functions of adaptive cytolytic T cells of the immune system. Aim
1 will determine how intrinsic ADRB2 signaling regulates the development and function of both effector and
memory CD8+ CTLs in response to intracellular infections. Aim 2 will identify the molecular pathway that drives
ADRB2-mediated memory development. Finally, Aim 3 will determine how long-acting β-agonist drugs alter
the course of a primary and secondary immune response to flu infection. These studies will inform us on the
role of the sympathetic nervous system in regulating cytolytic T cell function and how pharmacological agonists
alter those responses.
