What did studies of chemogenetic suppression of descending noradrenergic neurons find?

Studies of chemogenetic suppression of descending noradrenergic neurons measured 3 outcomes; the most studied are motor neuron soma size (1 study), neuromuscular junction innervation (1) and hindlimb muscle mass (1).

Motor neuron soma size

Suppressing nerve signals increased muscle mass in aged mice

Experiments in mice aged 1–25 months linked excessive signaling by norepinephrine, a nerve messenger, to age-related deterioration of nerves and muscles.Experiments in mice aged 1–25 months linked excessive signaling by norepinephrine, a nerve messenger, to age-related deterioration of nerves and muscles.
