Summary
The gut microbiome influences brain microglia, impacting neurodevelopment and function. This gut-brain axis connection offers new insights into neuropsychiatric and neurodegenerative disorders.
Area of Science:
- Neuroscience
- Microbiology
- Immunology
Background:
- The gut microbiome significantly impacts mammalian physiology, including metabolism and immune function.
- Microglia, the brain's immune cells, are crucial for neural health, and their dysfunction is linked to brain disorders.
- Emerging evidence suggests a link between the gut microbiome and microglial activity.
Purpose of the Study:
- To review the current literature on the gut microbiome's influence on microglia.
- To explore the bidirectional communication between gut microbiota and microglia.
- To discuss implications for neuropsychiatric and neurodegenerative disorders.
Main Methods:
- Literature review of recent studies.
- Analysis of findings on gut microbiome-microglia interactions.
- Synthesis of evidence from developmental and adult contexts.
Main Results:
- The gut microbiome and its metabolites can modulate microglia throughout life.
- Specific pathways of microbiota-microglia communication are beginning to be elucidated.
- This interaction plays a role in both normal brain function and disease pathogenesis.
Conclusions:
- The gut microbiome-microglia axis is a critical factor in brain health and disease.
- Understanding this crosstalk provides potential therapeutic targets for brain disorders.
- Further research is needed to fully elucidate the mechanisms and therapeutic potential.

01:05Physiology of Enteric Nervous System and Gut Health
The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...
01:22Introduction to the Human Microbiota
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, and disease...
01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
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...
01:18Functions 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...
01:22Gut-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...
