Activation mechanism of the β2-adrenergic receptor.
A third of marketed drugs act by binding to a G-protein-coupled receptor (GPCR) and either triggering or preventing receptor activation. Although recent crystal structures have provided snapshots of both active and inactive functional states of GPCRs, these structures do not reveal the mechanism by which GPCRs transition between these states. Here we propose an activation mechanism for the β(2)...
متن کاملNorepinephrine Inhibits Th17 Cells via β2-Adrenergic Receptor (β2-AR) Signaling in a Mouse Model of Rheumatoid Arthritis
BACKGROUND Norepinephrine (NE), a neurotransmitter released from the sympathetic nerves, has been shown to be involved in rheumatoid arthritis (RA). However, its role in the sympathetic nervous system in RA is divergent. Herein, we demonstrate that the sympathetic neurotransmitter NE exerts an anti-inflammatory effect in collagen-induced arthritis (CIA), a mouse model of RA, by inhibiting Th17 ...
متن کاملAdrenergic β2 Receptor Activation Stimulates Anti-Inflammatory Properties of Dendritic Cells In Vitro
Vagal nerve efferent activation has been shown to ameliorate the course of many inflammatory disease states. This neuro-modulatory effect has been suggested to rest on acetylcholine receptor (AChR) activation on tissue macrophages or dendritic cells (DCs). In more recent studies, vagal anti-inflammatory activity was shown involve adrenergic, splenic, pathways. Here we provide evidence that the ...
متن کاملJoint counts in inflammatory arthritis.
OBJECTIVES Counting the number of tender and swollen joints is an important aspect of assessing patients with an inflammatory arthritis. We provide a comprehensive overview of joint counts in inflammatory arthritis. This spans how they are undertaken, their use in clinical and research settings, their limitations and standardisation and who can perform them. METHODS We reviewed the literature...
متن کاملTargeting α- and β-Adrenergic Receptors Differentially Shifts Th1, Th2, and Inflammatory Cytokine Profiles in Immune Organs to Attenuate Adjuvant Arthritis
The sympathetic nervous system (SNS) regulates host defense responses and restores homeostasis. SNS-immune regulation is altered in rheumatoid arthritis (RA) and rodent models of RA, characterized by nerve remodeling in immune organs and defective adrenergic receptor (AR) signaling to immune cell targets. The SNS typically promotes or suppresses inflammation via α- and β2-AR activation, respect...
