Tabernanthalog, a Non-Hallucinogenic Psychedelic, Alleviates Cancer-Induced Cognitive Deficits via Serotonergic Pathways.

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
Cancer-related cognitive impairment (CRCI)-encompassing anxiety, depression, and memory deficits-significantly diminishes the quality of life in patients with cancer, yet remains underrecognized in clinical practice. In this study, we investigated the therapeutic potential of tabernanthalog (TBG), a non-hallucinogenic analog of psychedelic compounds, as a novel intervention for CRCI using a Lewis lung carcinoma (3LL) mouse model. Behavioral assessments revealed heightened anxiety-like behavior and memory impairment following 3LL cell transplantation. Biochemical analysis revealed reduced tryptophan levels in both blood and hippocampal tissue, accompanied by the downregulation of serotonergic receptor genes and upregulation of pro-inflammatory cytokine genes in the hippocampus of tumor-bearing mice. Additionally, microglial density and morphological activation were markedly elevated. TBG treatment reversed these behavioral deficits, improving both anxiety-related behavior and memory performance. These effects were associated with the normalization of microglial density and morphology, as well as the restoration of serotonergic receptor and cytokine gene expression. In vitro, TBG partially suppressed neuroinflammatory gene expression in BV-2 microglial cells exposed to conditioned medium from 3LL cells. Collectively, these findings suggest that TBG alleviates CRCI-like symptoms by modulating neuroinflammation and microglial activation. This study highlights TBG as a promising therapeutic candidate for improving cognitive and emotional functioning in patients with cancer.
