Development of Human Microbiota01:30

Development of Human Microbiota

54
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...

Gut-Brain Axis01:22

Gut-Brain Axis

164
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...

The Oral Microbiota01:27

The Oral Microbiota

63
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...

Microbiota of the Stomach and Small Intestine01:27

Microbiota of the Stomach and Small Intestine

67
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...

Anatomy of the Intestines01:23

Anatomy of the Intestines

92.8K
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...

Functions of the Gut Microbiota01:18

Functions of the Gut Microbiota

115
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...

Summary
This summary is machine-generated.

Down Syndrome (DS) gut microbiota composition is similar to healthy adults, potentially counteracting accelerated immune aging. Specific microbial increases in DS may link to behavioral traits.

Area of Science:

  • Microbiome research
  • Human genetics
  • Immunology

Background:

  • Down Syndrome (DS) is associated with premature aging.
  • Aging impacts the gut microbiota (GM)-host relationship.
  • Investigating GM in DS may reveal aging-related mechanisms.

Purpose of the Study:

  • To characterize the gut microbiota composition in adults with Down Syndrome.
  • To compare DS gut microbiome with age-matched healthy controls.
  • To explore potential links between gut microbes and DS health status.

Main Methods:

  • Observational study of 17 adult DS persons.
  • 454 pyrosequencing of the V4 region of the 16S rRNA gene for GM characterization.
  • Comparison of DS microbiome with healthy non-trisomic adults.

Main Results:

  • The dominant gut microbiota in DS individuals exhibited a mutualistic, immune-modulatory profile, similar to controls.
  • Specific microbial signatures were detected in subdominant GM fractions in DS.
  • Increased abundance of Parasporobacterium and Sutterella observed in DS.

Conclusions:

  • Gut microbiota may counteract accelerated immune senescence in Down Syndrome.
  • The identified microbial differences in DS warrant further investigation.
  • Sutterella abundance correlated with Aberrant Behavior Checklist scores, suggesting a role in DS behavioral features.
