Dietary-derived exosome-like nanoparticles (DELNs) influence gut microbiota composition. These nanoparticles, found in plant and animal foods, modulate bacteria through lipids and small molecules, not just miRNAs.
Area of Science:
- Microbiology
- Nutrition Science
- Biochemistry
Background:
- Food composition significantly impacts gut microbiota.
- Dietary-derived exosome-like nanoparticles (DELNs) are increasingly recognized for their role in host-microbe interactions.
- Previous research focused on proteins and miRNAs within DELNs, overlooking other bioactive components.
Purpose of the Study:
- To review the current knowledge on the antimicrobial capacity of DELNs.
- To explore the molecular mechanisms behind DELNs' effects on gut bacteria.
- To highlight the impact of DELNs on various bacterial species and gut microbiota modulation.
Main Methods:
- Literature review of studies investigating DELNs and their interaction with gut microbiota.
- Analysis of research on the composition of DELNs, including lipids, proteins, miRNAs, and small molecules.
- Synthesis of findings on the antimicrobial and modulatory effects of DELNs on bacterial species.
Main Results:
- DELNs from both plant and animal sources effectively modulate the gut microbiota.
- The antimicrobial and regulatory effects of DELNs are not solely attributed to their miRNA content.
- Lipids in the DELN membrane and other packed small molecules contribute to bacterial apoptosis, growth inhibition, or promotion.
Conclusions:
- DELNs play a significant role in shaping gut microbiota composition and function.
- Multiple components within DELNs, including lipids and small molecules, contribute to their bioactivity.
- Further research into DELNs' molecular mechanisms is warranted to understand their full impact on gut health.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
