Role of Endocannabinoid System Perturbation in Organophosphate-Mediated Metabolic Impairment and Neuroinflammation Rowan E. Arida, Dina M. Elgameel, Wesam Bassiouni, Vishal Sandilya, Salwa M. Abdallah, et al. Basic and Clinical Pharmacology and Toxicology, 2026 Organophosphates have been used for decades as pesticides, insecticides and herbicides, both in agricultural and industrial settings. However, their toxic effects on multiple body systems limit their safety. The clinical presentation of organophosphate toxicity varies depending on the route and duration of exposure. Although most research is focused on their cholinergic toxicity, emerging evidence points to their crucial contribution to metabolic dysfunction, including Type 2 diabetes and neuroinflammation. Beyond acetylcholinesterase inhibition, recent research highlights the potential role of organophosphates in disrupting endocannabinoid signalling, particularly by affecting endogenous ligands that modulate G protein–coupled receptors. This dysregulation may contribute to organophosphate‐induced metabolic disturbances and inflammation. This review aims to explore how chronic subtoxic exposure to organophosphates contributes to metabolic syndrome and neuroinflammation through disruption of insulin and endocannabinoid signalling. It highlights the role of the endocannabinoid system in mediating these effects and evaluates its potential as a therapeutic target in organophosphate‐induced toxicity.
Beyond weight loss: exploring the neurological ramifications of altered gut microbiota post-bariatric surgery Rashed T. Almheiri, Baraa Hajjar, Saif M. I. Alkhaaldi, Nadia Rabeh, Sara Aljoudi, et al. Journal of Translational Medicine, 2025 This review discusses findings related to neurological disorders, gut microbiota, and bariatric surgery, focusing on neurotransmitters, neuroendocrine, the pathophysiology of bacteria contributing to disorders, and possible therapeutic interventions. Research on neurotransmitters suggests that their levels are heavily influenced by gut microbiota, which may link them to neurological disorders such as Alzheimer's disease, Parkinson's disease, Multiple sclerosis, Depression, and Autism spectrum disorder. The pathophysiology of bacteria that reach and influence the central nervous system has been documented. Trends in microbiota are often observed in specific neurological disorders, with a prominence of pro-inflammatory bacteria and a reduction in anti-inflammatory types. Furthermore, bariatric surgery has been shown to alter microbiota profiles similar to those observed in neurological disorders. Therapeutic interventions, including fecal microbiota transplants and probiotics, have shown potential to alleviate neurological symptoms. We suggest a framework for future studies that integrates knowledge from diverse research areas, employs rigorous methodologies, and includes long-trial clinical control groups.
