The use of transepithelial models to examine host-pathogen interactions

Area of Science:

• Microbiology and Immunology
• Cell Biology
• Infectious Diseases

Background:

• Pathogens must overcome epithelial barriers to establish infections.
• Pathogen strategies include disrupting barrier function, transcytosis, and inducing immune cell recruitment.
• In vivo animal models often inadequately replicate human disease complexity and variables.

Purpose of the Study:

• To investigate bacterial pathogen strategies for overcoming epithelial barriers.
• To evaluate the utility of in vitro transepithelial models for studying host-pathogen interactions.
• To understand how pathogenic bacteria exploit host cells at the epithelial interface.

Main Methods:

• Development and utilization of in vitro transepithelial models.
• Integration of epithelial cells and pathogenic bacteria.
• Inclusion of additional cell types (e.g., neutrophils, dendritic cells) under specific conditions.

Main Results:

• In vitro models allow detailed study of bacterial interactions with epithelial cells.
• These models facilitate analysis of pathogen mechanisms for breaching epithelial barriers.
• The models provide insights into the bacteria-host relationship in a controlled microenvironment.

Conclusions:

• In vitro transepithelial models are valuable tools for studying epithelial barrier penetration by pathogens.
• These models enhance understanding of pathogenic bacteria's exploitation of host cells.
• Research using these models improves knowledge of early infection processes at the human epithelium.
