Norepinephrine-mediated regulation of 5HT1 receptor functioning in human platelets.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Adaptive changes in serotonergic 5HT1 receptor signalling are believed to underlie the therapeutic effectiveness of antidepressant drugs. Since cells are continuously exposed to neurotransmitters/neuromodulators, spatially and temporally integrated, the responsiveness of a receptor system is dependent upon the physio-pathological state of the cell and the interaction between different neurotransmitters. In the present work, we investigated heterologous regulation of 5HT1 receptors induced by norepinephrine (NE) in human platelets. NE platelet treatment induced a time and concentration dependent 5HT1 receptor desensitisation mediated by both alpha and beta receptors through activation of intracellular protein kinases. In particular NE, through PKC activation, regulated 5HT1 receptor phosphorylation on threonine residues, causing in turn serotonin receptor-G protein uncoupling and functional responsiveness drop. These results suggest that high NE levels (released i.e. during stress disorders) may play an important role in regulating the 5HT1 responsiveness and in controlling effectiveness of drugs acting on these neurotransmitter systems.
