Summary
Gut microbes produce butyrate, which protects against inflammation and colorectal cancer by activating GPR109a signaling. This highlights a key mechanism in host-microbe interactions for maintaining intestinal health.
Area of Science:
- Microbiology
- Immunology
- Gastroenterology
Background:
- The intestinal microbial ecosystem plays a vital role in host health, influencing nutrition, immunity, and barrier function.
- Understanding host-microbe interactions is crucial for addressing inflammatory and cancerous conditions in the gut.
Purpose of the Study:
- To investigate the protective mechanisms of microbial-derived metabolites against intestinal inflammation and colorectal cancer.
- To elucidate the specific signaling pathways involved in mediating these protective effects.
Main Methods:
- The study by Singh et al. (2014) focused on microbial-derived butyrate.
- Investigated the role of GPR109a signaling in mediating the effects of butyrate.
Main Results:
- Microbial-derived butyrate demonstrated protective activity against inflammation.
- Butyrate mediated its protective effects against colorectal cancer through GPR109a signaling.
Conclusions:
- GPR109a signaling is a key pathway through which microbial butyrate exerts its beneficial effects on host intestinal health.
- This finding provides insights into the therapeutic potential of targeting host-microbe interactions for gastrointestinal diseases.

222
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...

01:22Introduction to the Human Microbiota
209
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

01:18Functions of the Gut Microbiota
233
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...

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...

01:22Probiotics
296
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

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...
