Human intestinal organoids as models to study enteric bacteria and viruses

Area of Science:

• Microbiology
• Gastroenterology
• Biotechnology

Background:

• Traditional lab models like cell lines and animals have limitations in studying human gut interactions.
• Human intestinal organoids (HIOs) represent a significant advancement, offering physiologically relevant models.
• HIOs enable detailed investigation of complex host-microbe dynamics within the human gut environment.

Purpose of the Study:

• To review the application of HIOs in understanding enteric pathogen pathogenesis.
• To explore the use of HIOs for studying commensal gut microbes.
• To discuss the limitations of current HIO models and future directions for improvement.

Main Methods:

• Literature review of studies utilizing HIOs for host-microbe interaction research.
• Analysis of HIO applications in modeling bacterial and viral enteric infections.
• Examination of HIO use in studying beneficial gut microbiota.

Main Results:

• HIOs provide a superior model for investigating pathogen virulence and host responses.
• Studies using HIOs have advanced understanding of interactions with both pathogenic and commensal microbes.
• Limitations in current HIO systems are being addressed through technical and engineering innovations.

Conclusions:

• HIOs are a transformative tool for studying microbial pathogenesis and host-microbe interactions in the gut.
• The potential of HIOs extends to preclinical development of novel therapeutics and vaccines.
• Continued advancements in HIO technology promise to further enhance their utility in biomedical research.
