What causes the release of adrenaline in hypertensive rats?

Impaired neuronal reuptake, possibly due to dysfunction of the noradrenaline transporter (NET), increases the amount of NA in the synaptic cleft and could amplify the neuronal signal (3). Corelease of adrenaline (ADR) and subsequent stimulation of presynaptic β 2 -adrenoceptors could facilitate the release of the main neurotransmitter, NA (4).
