Multifaceted activities of type I interferon are revealed by a receptor antagonist.

abstract：:When we are frightened, our hearts beat more rapidly and forcefully so we can fight more intensely or run away faster. This fight-or-flight response is triggered by the release of norepinephrine from neurons of the sympathetic nervous system. Norepinephrine activates the classic β-adrenergic receptor-heterotrimeric G(...
