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 […]
Background Holotropic breathwork (Grof ® Breathwork), was developed by Stanislav Grof and Christina Grof as a ‘non-drug’ alternative technique to evoke altered states of consciousness (ASC). Interestingly, although HBW has been anecdotally reported to evoke experiences and mental health effects corresponding to those of psychedelic substances, the scientific literature on the matter is scarce. Aims
Ethanol (EtOH) is associated with IBD flares, but the exact mechanisms are not well-known. Gut dysbiosis and depleted luminal butyrate are both linked with IBD and EtOH exposure. We tested our hypothesis that EtOH-induced gut dysbiosis and depleted butyrate levels disrupt intestinal epithelial junctional proteins which facilitates ethanol and endotoxin interaction with intestinal microvascular endothelial
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

Chicoric acid (CA), a polyphenolic acid obtained from chicory and purple coneflower (Echinacea purpurea), has been regarded as nutraceutical to combat inflammation, virus and obesity. Parkinson’s Disease (PD) is a common neurodegenerative disorder, and microbiota-gut-brain axis might be the potential mechanism in the pathogenesis and development of PD. The results here demonstrated that oral pretreatments
Short-chain fatty acids (SCFAs) are considered the key molecular link between gut microbiota and pathogenesis of Parkinson’s disease (PD). However, the role of SCFAs in PD pathogenesis is controversial. Autophagy is important for the degradation of α-synuclein, which is critical to the development of PD. However, whether SCFAs can regulate autophagy in PD remains unknown.
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
