Evidence is supported the hypothesis that any changes in the composition and function of the gut microbiota play a fundamental role in a number of chronic inflammatory diseases including celiac disease (CD). In the last decade, several culture-independent methods have been developed to identify the components of the human microbiome. The study of microbiota based on nucleic acid analysis found ...
host-microbiota interaction is myd88-independent in the intestinal tract under physiologic condition
the role of microbiota in health and disease is the subject of rigorous investigation. several studies have demonstrated that microbiota and the pattern-recognition receptors contribute to intestinal tumourigenesis; the exact mechanism of which is still obscure. myd88 is the downstream effector of all toll-like receptors (tlrs) except tlr3. however, the alternative myd88-independent pathway is ...
Background: Colorectal cancer is the second most common cancer in the world which is mainly caused by epigenetic and environmental factors. Among these epigenetic factors, gut microbiota is an important one. Although it has not been proved a unique group of bacteria correlated with colorectal cancer, these findings have generally demonstrated differences between healthy and disease gut microbio...
Hepatitis B and C viruses are major public health problems. These viruses can chronically lead to liver disease such as fibrosis, cirrhosis, and hepatocellular carcinoma, which often increase mortality in these patients. According to previous studies, the liver is highly affected by changes in the microbiota of gastrointestinal tract and immune system damage caused by inflammation due to viral ...
Root canal disinfection is one of the main factors governing success of endodontic therapy. Antimicrobial photodynamic therapy (aPDT) is presented as a promising antimicrobial therapy that can eliminate microbiota present in infected root canal systems. In this study, a series of experiments investigated the effects of aPDT on cell viability and biofilm degradation ability of endopathogenic mic...
Some organisms may modulate a healthy state or cause disorders by disruption or induction of several signaling pathways in human body. According to recent evaluations, numerous metabolic disorders such as diabetes, obesity, cardiovascular diseases, mental disorders, and cancers are as the result of bacterial interactions with the host. Various species of the bacteria, called commensal microbio...
fermentation may amplify the specific nutrient or phytonutrient content of foods, the ultimate value of which is associated with mental health furthermore, the microbes associated with fermented foods may also influence brain health via direct and indirect pathways. this review is intended to guide the development of fermented foods for enhanced human mental health benefits. we searched databas...

Extracellular vesicles, naturally released from all cell types including bacteria, are of great importance in medical microbiology due to transporting a variety of biomaterials, enzymes, and virulence factors, regulating immunity, and having roles in colonization and initiation of signaling pathways. These vesicles are also secreted from microbiota in the gastrointestinal tract and affect the h...
Introduction: The intestine, as an important part of the human gastrointestinal tract, provides a favorable milieu for the growth and development of a diverse and large population (approximately 1000 species) of bacteria. Currently, the presence of a cohesive relationship between intestinal bacteria and the host is being well studied and identified. According to the available scientific evidenc...
