TLDR
The biological interplay between gut-brain axis is discussed, and how this communication may be dysregulated in neurological diseases is explored, and new insights in modification of gut microbiota composition are highlighted.Abstract:
Development of central nervous system (CNS) is regulated by both intrinsic and peripheral signals. Previous studies have suggested that environmental factors affect neurological activities under both physiological and pathological conditions. Although there is anatomical separation, emerging evidence has indicated the existence of bidirectional interaction between gut microbiota, i.e., (diverse microorganisms colonizing human intestine), and brain. The cross-talk between gut microbiota and brain may have crucial impact during basic neurogenerative processes, in neurodegenerative disorders and tumors of CNS. In this review, we discuss the biological interplay between gut-brain axis, and further explore how this communication may be dysregulated in neurological diseases. Further, we highlight new insights in modification of gut microbiota composition, which may emerge as a promising therapeutic approach to treat CNS disorders.read more

Toxicity of Microplastics and Nanoplastics in Mammalian Systems
TL;DR: The prevailing data suggest that micro- and nanoplastic accumulation in mammalian and human tissues would likely have negative, yet unclear long-term consequences, and there is a need for cellular and systemic toxicity due to micro-and nanoplastics to be better illuminated, and the underlying mechanisms defined by further work.

The Gut-Brain Axis: How Microbiota and Host Inflammasome Influence Brain Physiology and Pathology.
TL;DR: The status of the knowledge and the open questions in the field focusing on the function of intestinal microbial metabolites or products on CNS cells during healthy and inflammatory conditions, such as multiple sclerosis, Alzheimer's and Parkinson’s diseases, and also neuropsychiatric disorders are discussed.
Journal ArticleDOI
Role of gut-brain axis, gut microbial composition, and probiotic intervention in Alzheimer's disease.
TL;DR: As aging together with poor diet and gut-derived inflammatory response due to dysbiosis contributes to the pathogenesis of AD, modification of gut microbial composition by uptake of probiotic-rich food can act as a preventive/therapeutic option for AD.

TL;DR: Both benefits and pitfalls of molecular biology and proteomics analyses are discussed, including the different mass spectrometry-based analytical techniques, highlighting how these investigation strategies are powerful tools to study the biology of glioblastoma, as well as to develop advanced methods for the management of this pathology.
Journal ArticleDOI
Gut microbial molecules in behavioural and neurodegenerative conditions.
TL;DR: Bacterial metabolites with known or suspected neuromodulatory activity are described, mechanisms of signalling pathways from the gut microbiota to the brain are defined and direct effects that gut bacterial molecules are likely exerting on specific brain cells are discussed.

TL;DR: The scope of the present article is to review the available studies on the enteric nervous system in Parkinson’s disease patients and in animal models of the disease, and to discuss the strategies that will help in the understanding of the roles of the entero-nervous system, both in the pathophysiology of the Disease and in the route of entry for a putative environmental factor to initiate the pathological process.

The Vagus Nerve in the Neuro-Immune Axis: Implications in the Pathology of the Gastrointestinal Tract.
TL;DR: The vagus nerve is the longest nerve of the organism and a major component of the parasympathetic nervous system which constitutes the autonomic nervous system (ANS), with the sympathetic nervous system, which is a therapeutic target in the treatment of chronic inflammatory disorders where TNFα is a key component.

Vagal neurocircuitry and its influence on gastric motility.
TL;DR: This Review summarizes the organization and function of vagovagal reflex control of the upper gastrointestinal tract, presents data on the plasticity within these neurocircuits after stress, and discusses the gastrointestinal dysfunctions observed in Parkinson disease as examples of physiological adjustment and maladaptation of these reflexes.
