Palmitoyl Serine: An Endogenous Neuroprotective Endocannabinoid-Like Entity After Traumatic Brain Injury.
Article in Journal of neuroimmune pharmacology : the official journal of the Society on NeuroImmune Pharmacology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.
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
The endocannabinoid (eCB) system helps recovery following traumatic brain injury (TBI). Treatment with 2-arachidonoylglycerol (2-AG), a cerebral eCB ligand, was found to ameliorate the secondary damage. Interestingly, the fatty acid amino acid amide (FAAA) N-arachidonoyl-L-serine (AraS) exerts similar eCB dependent neuroprotective. The present study aimed to investigate the effects of the FAAA palmitoyl-serine (PalmS) following TBI. We utilized the TBI model in mice to examine the therapeutic potential of PalmS, injected 1 h following closed head injury (CHI). We followed the functional recovery of the injured mice for 28 days post-CHI, and evaluated cognitive and motor function, lesion volume, cytokines levels, molecular signaling, and infarct volume at different time points after CHI. PalmS treatment led to a significant improvement of the neurobehavioral outcome of the treated mice, compared with vehicle. This effect was attenuated in the presence of eCBR antagonists and in CB2-/- mice, compared to controls. Unexpectedly, treatment with PalmS did not affect edema and lesion volume, TNFα and IL1β levels, anti-apoptotic mechanisms, nor did it exert improvement in cognitive and motor function. Finally, co-administration of PalmS, AraS and 2-AG, did not enhance the effect of the individual drugs. We suggest that the neuroprotective action of PalmS is mediated by indirect activation of the eCB receptors following TBI. One such mechanism may involve receptor palmitoylation which has been reported to result in structural stabilization of the receptors and to an increase in their activity. Further research is required in order to establish this assumption.
