The gut-brain axis (GBA) refers to the bi-directional communication thatoccurs between the gut and the brain. Recently, studies have highlightedthe important role of nutrition in modulating the GBA. We will delve into thisexciting area of research and understand how certain diets and foods maybe linked to mood and mental health. Our understanding of the gut-brain […]

The gut microbiota is the set of microorganisms present in the gut, and it is connected to the central nervous system via the gut-brain axis. Despite there is not a definitive description of the eubiotic microbiota architecture, numerous studies have demonstrated its involvement in human behaviour and its relationship with several pathologies. This is a systematic review about the association between dysbiosis on
Parkinson’s disease (PD) is a neurological disorder characterized by motor dysfunction, which can also be associated with non-motor symptoms. Its pathogenesis is thought to stem from a loss of dopaminergic neurons in the substantia nigra pars compacta and the formation of Lewy bodies containing aggregated α-synuclein. Recent works suggested that lipids might play a pivotal
Olfactory dysfunction is an early pre-motor symptom of Parkinson’s disease (PD) but the neural mechanisms underlying this dysfunction remain largely unknown. Aggregation of α-synuclein is observed in the olfactory bulb (OB) during the early stages of PD, indicating a relationship between α-synuclein pathology and hyposmia. Here we investigate whether and how α-synuclein aggregates modulate neural
Microbial communities perform emergent activities that are essentially different from those carried by their individual members. The gut microbiome and its metabolites have a significant impact on the host, contributing to homeostasis or disease. Food molecules shape this community, being fermented through cross-feeding interactions of metabolites such as lactate, acetate, and amino acids, or products derived from macromolecule degradation. Mathematical and

Brain-derived neurotrophic factor (BDNF) is a protein that performs a neurotrophic function.BDNF and its receptors are widely expressed in the nervous system and can promote the growthof neurons and the formation of neuronal synapses in the brain. Studies have shown that a lack ofBDNF can lead to impairment of memory and cognitive functions, indicating that

The gut is connected to the CNS by immunological mediators, lymphocytes, neurotransmitters, microbes and microbial metabolites. A mounting body of evidence indicates that the microbiome exerts significant effects on immune cells and CNS cells. These effects frequently result in the suppression or exacerbation of inflammatory responses, the latter of which can lead to severe tissue

The gut microbiota has gained importance through the years due to its significant influences on the maintenance of human health. A wide variety of microorganisms shape this gut microbiota, which preserves health with the modulation of the immune system, enhancement of the nutrients absorption, or the protection against pathogens’ colonization. The disruption of this microenvironment

Nausea, heartburn, indigestion, constipation, andstomach pain are all kinds of gastrointestinal problems we have faced before. They are easy to dismissas merely an upset stomach, but this mentality couldbuild up and ultimately be detrimental to mental and physicalhealth. Improperly caring for the digestive system can lead toextensive intestinal health issues. The microbiome is a collectionof

The composition of the gut microbiota, including Akkermansia muciniphila (A. muciniphila), is altered in many neurological diseases and may be involved in the pathophysiological processes of Parkinson’s disease (PD). A. muciniphila, a mucin-degrading bacterium, is a potential next-generation microbe that has anti-inflammatory properties and is responsible for keeping the body healthy. As the role of A. muciniphila in PD has
