Effects of selected alkaloids on postnatal neurogenesis - in vivo and in vitro studies - literature review.
Review in Psychopharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
rationalePostnatal neurogenesis is the process of new nerve cell formation that occurs after birth. The disruption of the neurogenesis process is a significant hypothesis in the development of mental disorders and diseases such as depression, anxiety disorders or schizophrenia, as well as neurodegenerative diseases such as Alzheimer's disease.
objectiveThe objective of this study was to investigate, based on the existing literature, whether naturally occurring alkaloids have an impact on postnatal neurogenesis and, if so, whether this effect is beneficial or detrimental.
methodsAn advanced search was conducted using the databases PubMed and Google Scholar, employing the terms "alkaloid" AND "neurogenesis." The research focused on in vitro studies using cell lines, including C17.2, HT-22, BV-2, and SH-SY5Y, in addition to in vivo studies involving zebrafish (Danio rerio), Wistar rats and mice.
resultsThe research indicated that some of the alkaloids have a beneficial impact on postnatal neurogenesis through their pleiotropic mechanisms of action. This is evidenced by their anti-inflammatory and anti-oxidant effects, ability to increase brain-derived neurotrophic factor (BDNF) levels, promotion of synapse formation, and direct effect on neural progenitor cells proliferation. However, some alkaloids have been shown to have a negative effect on postnatal neurogenesis through mechanisms that are the opposite of those mentioned above.
conclusionThere is currently a lack of consensus on whether neurogenesis occurs in Homo sapiens. However, it is known that alkaloids affect the model organisms in different ways, which suggests a potential for these substances to be used therapeutically. Further research is therefore required to investigate this possibility.
