Up-regulation of the Trace Amine Receptor, TAAR-1, in the Prefrontal Cortex of Individuals Affected by Schizophrenia.
Article in Schizophrenia bulletin, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
background and hypothesisType-1 trace amine-associated receptors (TAAR1) modulate dopaminergic and glutamatergic neurotransmission and are targeted by novel antipsychotic drugs. We hypothesized that schizophrenia (SCZ) causes adaptive changes in TAAR1 expression in the prefrontal cortex. STUDY
designWe measured TAAR1 mRNA and protein levels by quantitative PCR and immunoblotting in post-mortem prefrontal cortical samples obtained from 23 individuals affected by SCZ and 23 non-schizophrenic controls (CTRL). Data were correlated with a number of variables in both groups. STUDY
resultsTAAR1 mRNA levels were largely increased in the SCZ prefrontal cortex, and did not correlate with age, age at onset and duration of SCZ, or duration of antipsychotic treatment. For the analysis of TAAR1 protein levels, CTRL and SCZ were divided into 2 subgroups, distinguished by the extent of neuropathological burden. CTRL with low neuropathological burden (LNB) had lower TAAR1 protein levels than CTRL with high neuropathological burden (HNB), whereas no changes were found between LNB and HNB in the SCZ group. TAAR1 protein levels were lower in CTRL with LNB with respect to all SCZ samples or to SCZ samples with LNB. In the SCZ group, levels showed an inverse correlation with the duration of antipsychotic treatment and were higher in individuals treated with second-generation antipsychotics as compared with those treated with first-generation antipsychotics.
conclusionsThe up-regulation of TAAR1 observed in the SCZ prefrontal cortex supports the development of TAAR1 agonists as new promising drugs in the treatment of SCZ.
