BACKGROUND The etiology of dental caries is multifactorial, but frequent consumption of free sugars, notably sucrose, appears to be a major factor driving the supragingival microbiota in the direction of dysbiosis. Recent 16S rRNA-based studies indicated that caries-associated communities were less diverse than healthy supragingival plaque but still displayed considerable taxonomic diversity be...
Clostridium difficile infection (CDI) is the most common nosocomial infection in the United States, being associated with high recurrence and persistence rates. Though the relationship between intestinal dysbiosis and CDI is well known, it is unclear whether different forms of dysbiosis may potentially affect the course of CDI. How this is further influenced by C. difficile-directed antibiotics...
The interaction between genetic predisposition and environmental factors are of great significance in the pathogenesis and development of autoimmune diseases (AIDs). The human mucosa is the most frequent site that interacts with the exterior environment, and commensal microbiota at the gut and other human mucosal cavities play a crucial role in the regulation of immune system. Growing evidence ...
High throughput methods have increased knowledge about the epigenome and microbiome, and allowed determination of the plausible link between the gut microbiome and epigenetic modification of the host. This has shed light on the development of various diseases such as immune-mediated, metabolic, and cardiovascular diseases, and even cancer. Dysbiosis, imbalanced gut microbiome which is frequentl...
Pattern recognition receptors link metabolite and bacteria-derived inflammation to insulin resistance during obesity. We demonstrate that NOD2 detection of bacterial cell wall peptidoglycan (PGN) regulates metabolic inflammation and insulin sensitivity. An obesity-promoting high-fat diet (HFD) increased NOD2 in hepatocytes and adipocytes, and NOD2(-/-) mice have increased adipose tissue and liv...
Recent advances from microbiome and host response mechanistic studies indicate that periodontitis is not a bacterial infection in the classical sense but rather results from dysbiosis owing to a breakdown in host-microbe homeostasis. Accordingly, periodontitis is induced in susceptible hosts by a polymicrobial community, in which different members have distinct roles that converge synergistical...
INTRODUCTION Dysbiosis is associated with a number of gastrointestinal and systemic disorders. There is a need for selectively acting antimicrobial agents capable of inhibiting the growth of potentially pathogenic microorganisms, or those found to be out of balance, while not negatively impacting the bulk gastrointestinal tract microflora. OBJECTIVE The purpose of this in vitro study is to ex...
In this review we elucidate the role of gut microbiota as the plausible missing link between food and health, focusing on chronic kidney disease (CKD). Microbiota, the microbial community harboured in the large intestine, is considered a symbiotic "supplementary organ". It contributes to digestion, mainly through two catabolic pathways: saccharolytic (fermentation) or proteolytic (putrefaction)...
Sphingolipids play important roles in mitigating cellular heat and oxidative stress by altering membrane fluidity, receptor clustering and gene expression. Accumulation of signaling sphingolipids that comprise the sphingosine rheostat, pro-apoptotic sphingosine (Sph) and pro-survival sphingosine-1-phosphate (S1P) is key to determining cell fate. Reef-building corals and other symbiotic cnidaria...
