Knocking Out TAAR5: A Pathway to Enhanced Neurogenesis and Dopamine Signaling in the Striatum.
Article in Cells, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The member of trace-amine associated receptor family, TAAR5 receptor was suggested to recognize tertiary amines, mostly in the olfactory system; however, knocking out the receptor TAAR5 in mice showed an enhancing effect on adult neurogenesis and dopamine neurotransmission in the striatum. To estimate the role of the TAAR5, we performed gene expression profiling of striatal samples from TAAR5 knockout (KO) mice and their wild-type littermates. The higher expression of several genes involved in dopaminergic signaling and the downregulation of genes associated with gliogenesis were revealed in TAAR5-KO mice. Meanwhile, the upregulating effect of TAAR5 knockout on genes was associated with neurogenesis and synaptogenesis. The estimation of cell-type relative abundance through the deconvolution of RNA sequencing data demonstrated that TAAR5-KO striatum samples contain more D2 dopamine receptor-expressing medium spiny neurons but fewer astrocytes than wild-type mice. Our findings indicate that previously identified improvement in cognitive functions and motor coordination in TAAR5-KO mice may activate genes involved in neurogenesis, synaptogenesis, and synapse organization in the striatum. These data suggest that the pharmaceutical targeting of TAAR5 may improve striatum-dependent cognitive or motor functions. At the same time, a more detailed investigation of future TAAR5 antagonists' effect on glia development is necessary.
