Intestinal microbiota improves inflammation and cognitive function in the brain of a7nAChR deficient rat through the gut brain axis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
To investigate the role of intestinal flora and cholinergic anti-inflammatory pathways in the gut-brain axis, using oral gavage and intraperitoneal injection of methyllycaconitine (MLA). MLA was administered at a dose of 4 mg/kg for 30 days, either orally or via intraperitoneal injection. Rats were then assessed for behavioral changes, inflammatory markers, neurotransmitters, neuroreceptors, and intestinal mucosal barrier integrity. Rats receiving MLA via intraperitoneal injection exhibited significant behavioral abnormalities compared to the control and orally administered MLA groups. The levels of IL-1β were elevated in both intestinal and hippocampal tissues, while IL-10 levels were decreased. Brain-derived neurotrophic factor (BDNF) was significantly lower in hippocampal tissues. Furthermore, α7nAChR expression was reduced in hippocampal tissues, accompanied by an increase in 5-HT3A receptors. The intestinal mucosal barrier was compromised, as evidenced by reduced expression of ZO-1 and Occludin, along with increased IL-1β and decreased IL-10 levels in the gut. Our findings suggest that oral gavage of MLA does not induce cognitive impairment in rats compared to intraperitoneal injection, possibly due to the involvement of intestinal flora in the protective effects of CAP.
