Psora-4, a Kv1.3 Blocker, Enhances Differentiation and Maturation in Neural Progenitor Cells.
Article in CNS neuroscience & therapeutics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
aimThe self-repair ability of neural progenitor cells (NPCs) has been found to be activated and protected in several therapies helpful in multiple sclerosis (MS), an inflammatory demyelinating disease of the CNS. As a potential therapeutic target in MS, the role of the ion channel Kv1.3 in NPC self-repair has received limited attention. The aim of this study was to explore the effects of a selective Kv1.3 blocker on NPC neuronal differentiation and maturation.
methodsA small-molecule selective blocker for Kv1.3, Psora-4, was added to the differentiation medium of cultured mouse NPCs to assess its effect on NPC differentiation efficiency. Both a polypeptide Kv1.3 blocker and Kv1.3-specific RNA interference were used in parallel experiments. Further, the maturity of newborn neurons in the presence of Psora-4 was measured both by morphological analysis and by whole-cell patch clamping.
resultsPsora-4 induced a significant increase in the percentage of neurons. Knockdown of Kv1.3 in NPCs also promoted neuronal differentiation. Both morphological and electrophysiological analyses suggested that NPC-derived neurons in the presence of Psora-4 were more mature.
conclusionOur studies reveal a crucial role for the ion channel Kv1.3 in the regulation of NPC differentiation and maturation, making Psora-4 a promising candidate molecule for MS treatment.
