Immunity & Ageing : I & A
|August 7, 2013
Summary
Aging alters the gut microbiota and immune system, increasing inflammation and disease risk. Nutraceuticals may help by correcting these age-related changes in the gut.
Area of Science:
- Gastroenterology and immunology research focusing on the aging gut.
- Investigating the complex interplay between the intestinal microbiota and the gut immune system.
Background:
- The aging process significantly modifies both the gut microbiota and immune system, leading to a chronic low-grade inflammatory state.
- Western dietary habits can further negatively impact microbiota composition and impair immune responses in the elderly.
Discussion:
- Age-related changes in the gut microbiome and immune function contribute to increased susceptibility to diseases like inflammatory bowel disease and colorectal cancer.
- Nutraceutical supplementation is increasingly explored as a strategy to counteract age-related gut dysfunctions.
Key Insights:
- Aging disrupts the delicate balance of the intestinal habitat, compromising immune homeostasis.
- Dietary patterns in Western societies exacerbate age-induced gut dysbiosis and immune impairment.
Outlook:
- Further research is needed to identify specific components of the aged microbiota.
- A deeper understanding of gut mucosal immunity function in the elderly is crucial for developing effective interventions.

01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:22Gut-Brain Axis
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...
01:18Functions of the Gut Microbiota
The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...
01:27The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
01:23Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
