Cover Story Current Issue

Epidemiological evidences provide proof of concept that certain pesticides are involved in metabolic disorders, but also in the pathophysiology of Parkinson's disease (PD). In addition, large prospective cohort studies reported that type 2 diabetes (T2D) and PD are epidemiologically associated, including an elevated risk of developing PD in patients with T2D.

The impact of gut-liver-derived mediators on the organ crosstalk with brain, heart, and kidney: A systematic review

Introduction

The current understanding of interactions and crosstalk among essential organs remains incomplete, mainly due to the limitations of studies on the systemic mechanisms at play. The gut and the liver are essential for the functioning of the entire body, and their derived mediators circulate through blood or lymph, impacting other organs like the brain, heart, and kidneys.

Aim

This publication reviews gut-liver-derived mediators, which were tested and validated in vivo in humans and rodents, together with the current knowledge of their systemic effects on key vital organs.

Method

Original articles published up to February 2025, based on clinical trials or in vivo experimental models, were retrieved from PubMed and Web of Science.

Results

During this systematic analysis, 28 gut-liver-derived mediators were identified from 52 publications and classified into five distinct groups based on their molecular characteristics: (a) low molecular weight metabolites, (b) endotoxins, (c) hormones, (d) lipids and (e) proteins. Additionally, the mechanism of action for each of these molecules was specified, aimed at providing a mechanistic overview of their effects on the brain, heart, and kidneys.

Discussion

The diverse and occasionally conflicting impact of the identified mediators on comorbidities necessitates further investigations pinpointing key mechanisms influencing disease genesis and progression.

Conclusion

Our research shows the necessity of a thorough examination of these mediators, exploring their diagnostic and therapeutic potential in a holistic multi-organ setting, to elucidate inter-organ crosstalk.
