Our gut interior is a vital and rich ecosystem containing billions of microorganisms which are in competition with one another for resources such as nutrients and space. In a healthy person, a delicate balance is maintained, with abundant good bacteria out-competing the disease-causing bad bacteria. When the bad bacteria start to take over however, this balance can become disrupted, leading…

Having a food sensitivity is life-altering. Avoiding a particular food or food component can be challenging and avoidance is currently our primary treatment option for this kind of condition. Given that one fifth of the population will be affected by food sensitivity in their lifetime, discovering alternatives to help manage them is critical. Food sensitivities have been increasing at a…

The ability to distinguish between “self” and “non-self” is the hallmark of a healthy immune system. Immune cells must be able to recognize pathogenic “non-self” antigens (i.e. microbial pathogens) and mount an appropriate immune response while remaining quiescent towards “self” agents (i.e. commensal microbes) that are harmless to our health. Nowhere else in the human body is this process more…

Our immune system fights pathogens, repairs wounded tissue and eliminates dead cells. It also acts to ensure we tolerate our own cells, food intake, and other environmental components, as well as the indigenous microbiota. In the presence of pathogenic invaders and other noxious insults, a resilient immune response is crucial to effectively eliminate the source of stimulation in a way…

Other than gut microbiota's well-known functions, which include nutrient metabolism and absorption, xenobiotic and drug metabolism, and immune development, its role in protecting against pathogens has been poorly characterized. Previous research has identified some microbiota-mediated colonization resistance mechanisms, while little is known about whether microbial metabolites may also limit pathogen colonization. A new study, led by Dr. Denise Monack from…

The gut microbiota's composition and activity can be modulated by both environmental and host-derived factors. Among them, the homeostatic functions of immunoglobulin A (IgA) on gastrointestinal commensal bacteria has recently been confirmed in humans with IgA deficiency. A new study, led by Dr. Keiichiro Suzuki from the Graduate School of Medicine at Kyoto University and RIKEN Yokohama Institute (Japan), has…

According to many scientific studies, having a balanced gut microbiota is essential for gut health. Just like a big city, where the whole community works together to make the place work, our gut is populated by trillions of microbes that help us live a healthy life. “We have a lot of bacteria in our body and the reason they are…

Although gut microbiota profiles differ remarkably between healthy individuals, several features have been suggested to define a “healthy gut microbiome”. First of all, our gut microbiota can be understood, in many cases, to be redundant given that many bacterial species have similar functions. Furthermore, a healthy gut microbiome is temporally stable and resistant to perturbations and, over time, is more…

Secretory immunoglobulin A (IgA) is the most abundant antibody in mucosal secretions and has been recognized as a first line of defense in protecting the intestinal epithelium from enteric pathogens. Despite its important role in mucosal immunity and intestinal homeostasis, IgA deficiency—defined by undetectable seric IgA titers (<0.07 mg/ml) with normal IgG concentration—is related to a very mild phenotype in…
