Microfluidic Tools for Probing Fungal-Microbial Interactions at the Cellular Level
Published on: June 23, 2022
Abstract:
Many different fungi, including yeasts and molds, can be found in the intestinal tract of humans constituting the gut mycobiome. In case the bacterial flora is altered, the fungal flora may react inversely. By a so-called fungal diet, however, the composition of the mycobiome can hardly be influenced. Whereas some fungi are only transiently present in the gut after oral uptake, others, such as Candida, Saccharomyces, Rhodotorula, Trichosporon, Geotrichum, amongst others, are members of the residential, autochthonous gut flora. Some of these fungi exert beneficial effects, for example by synthesizing useful materials. Rhodotorula can produce fatty acids and carotenoids. Others are able to metabolize toxic compounds, for example mycotoxins as well as procarcinogenic items in food. Toxins, as well as pathogenic bacteria, can be bound to mannans on the surface of fungi und can consequently be exported. Some fungi are said to exert probiotic activities. Certain fungal constituents, such as glucans, may even stimulate the immune system. On the other hand, some fungi cannot only colonize the gut asymptomatically but can also be noxious under certain conditions when, for example, the bacterial flora is disturbed. By means of their virulence factors, they can damage the gut epithelium and even penetrate into the Mukosa inducing inflammation, They can also aggravate chronic inflammatory processes. Fungi play a role in the development of obesity. Lastly, fungi in the gut represent a reservoir from which they may spread to other sites when the conditions are favorable.
Insights
The human gut harbors a complex fungal community, the mycobiome, which can influence health or cause disease. Understanding the gut mycobiome is crucial for human health and disease management.
Area of Science:
- Microbiology
- Gastroenterology
- Immunology
Background:
- The human intestinal tract hosts a diverse fungal population, known as the gut mycobiome, comprising yeasts and molds.
- The gut mycobiome can dynamically respond to alterations in the gut bacterial flora.
- While a fungal diet has limited impact, some fungi are permanent residents of the gut flora.
Purpose of the Study:
- To explore the dual role of the gut mycobiome in human health.
- To investigate the beneficial and detrimental effects of gut fungi.
- To understand the implications of gut fungi in disease development and progression.
Main Methods:
- Review of existing literature on gut fungi and their interactions.
- Analysis of fungal components and their biological activities.
- Examination of fungal roles in gut health and disease pathogenesis.
Main Results:
- Some gut fungi, like Rhodotorula, offer benefits by producing beneficial compounds (fatty acids, carotenoids) and metabolizing toxins.
- Fungal surface mannans can bind and neutralize toxins and pathogenic bacteria, aiding in their elimination.
- Certain fungi exhibit probiotic properties and their components, such as glucans, can modulate the immune system.
- Conversely, some fungi can become pathogenic, damaging the gut lining, inducing inflammation, and exacerbating chronic conditions.
- Gut fungi are implicated in obesity development and can serve as a reservoir for systemic infections.
Conclusions:
- The gut mycobiome possesses a complex, dual role, contributing to both beneficial functions and pathogenic processes.
- Fungal dysbiosis can lead to gut inflammation, metabolic disorders like obesity, and increased susceptibility to infections.
- Further research into the gut mycobiome is essential for developing targeted therapeutic strategies for various health conditions.
