C. elegans: model host and tool for antimicrobial drug discovery.

Area of Science:

• * Nematology
• * Immunology
• * Microbiology

Background:

• * Caenorhabditis elegans is a model organism extensively used in biological research for nearly four decades.
• * The nematode relies solely on innate immunity to combat pathogen attacks, lacking an adaptive immune system.
• * Microbial infections in C. elegans activate specific innate immune responses, including the production of antimicrobial peptides.

Purpose of the Study:

• * To review antimicrobial peptides (AMPs) and proteins in C. elegans with potential for novel antibiotic development.
• * To describe C. elegans infection systems as platforms for large-scale in vivo screening of antimicrobial drugs.
• * To highlight the potential of C. elegans models for developing innovative human therapies.

Main Methods:

• * Review of scientific literature on C. elegans immunity and antimicrobial peptides.
• * Description of C. elegans infection models for drug discovery.
• * Analysis of innate immune responses to microbial pathogens.

Main Results:

• * Identification of various antimicrobial peptide families in C. elegans.
• * Demonstration of C. elegans infection systems as effective tools for in vivo drug screening.
• * Recognition of the clinical relevance of microbes studied in C. elegans models.

Conclusions:

• * C. elegans serves as a valuable model for studying innate immunity and identifying antimicrobial compounds.
• * Large-scale screens using C. elegans infection models offer promising avenues for discovering new antibiotics.
• * This research opens perspectives for developing novel human therapeutic strategies against infectious diseases.
