Gut-associated dendritic cells (DC) synthesize all-trans retinoic acid, which is required for inducing gut-tropic lymphocytes. Gut-associated DC from MyD88 2/2 mice, which lack most TLR signals, expressed low levels of retinal dehydrogenases (critical enzymes for all-trans retinoic acid biosynthesis) and were significantly impaired in their ability to induce gut-homing T cells. Pretreatment of ...
Background: Autism spectrum disorders (ASD) are complex developmental characterised by several levels of social interaction and communication difficulties. The prevalence children with ASD worldwide is around 1:160, the number cases autism has increased significantly. oral microbiome a diverse microbial biofilm second most microbiota in human body after gut. Several factors, such as lifestyle h...
Alcohol dependence has traditionally been considered a brain disorder. Alteration in the composition of the gut microbiota has recently been shown to be present in psychiatric disorders, which suggests the possibility of gut-to-brain interactions in the development of alcohol dependence. The aim of the present study was to explore whether changes in gut permeability are linked to gut-microbiota...
Aims Accumulating evidence for the influence of the gut microbiota on the bidirectional communication along the gut-brain axis suggests a role of the gut microbiota in eating disorders (EDs) and alcohol and substance use disorders. The potential influence of altered gut microbiota (dysbiosis) on behaviors associated with such disorders may have implications for developing therapeutic interventi...
Background The intestine is inhabited by a tremendous number of microorganisms, which provide many benefits to nutrition, metabolism and immunity. Mucosal barriers by intestinal epithelial cells make it possible to maintain the symbiotic relationship between the gut microbiota and the host by separating them. Recent evidence indicates that mucosal barrier dysfunction contributes to the developm...
BACKGROUND Gut ischemia/reperfusion (I/R) injury is a serious condition in intensive care patients. Activation of immune cells adjacent to the huge endothelial cell surface area of the intestinal microvasculature produces initially local and then systemic inflammatory responses. Stimulation of the vagus nerve can rapidly attenuate systemic inflammatory responses through inhibiting the activatio...
The regulation of insect gut physiology is complex and involves the interactions of a number of mechanisms, including the neural regulation of gut contraction by altering neural input and the modulation of gut contractions by neuropeptides directly affecting the muscle. The FGLa-type allatostatins (FGLa/ASTs) are known brain/gut peptides with numerous physiological roles, including modulation o...
Alterations in the composition of the gut microbiota have profound effects on human health. Consequently, there is great interest in identifying, characterizing, and understanding factors that initiate these changes. Despite their high prevalence, studies have only recently begun to investigate how viral lung infections have an impact on the gut microbiota. There is also considerable interest i...
Emerging evidence has suggested a potential impact of gut microbiota on the pathophysiology of heart failure (HF). However, it is still unknown whether HF is associated with dysbiosis in gut microbiota. We investigated the composition of gut microbiota in patients with HF to elucidate whether gut microbial dysbiosis is associated with HF. We performed 16S ribosomal RNA gene sequencing of fecal ...
OBJECTIVES The gut feelings of doctors can act as triggers and modulators of the diagnostic process. This study explored the existence, significance, determinants and triggers of gut feelings among Spanish general practitioners. DESIGN Qualitative study using focus groups. Thematic content analysis. SETTING Primary healthcare centres in Majorca (Spain). PARTICIPANTS 20 purposively sampled...
