Summary
Humanized mouse models better mimic human bacterial infections than traditional models. These models are crucial for developing new treatments and vaccines against challenging pathogens like Mycobacterium tuberculosis.
Area of Science:
- Microbiology
- Immunology
- Infectious Diseases
Background:
- Bacterial infections pose a global health challenge, exacerbated by rising multidrug-resistant strains.
- Conventional mouse models inadequately represent human-specific disease tropisms and phenotypes.
- There is a critical need for improved small animal models for developing effective treatments and vaccines.
Purpose of the Study:
- To review the development and application of humanized mouse models for studying bacterial infections.
- To highlight the advantages of humanized models over conventional models in recapitulating human disease.
- To discuss the insights gained from humanized mouse models regarding human immune responses to specific bacterial pathogens.
Main Methods:
- Review of historical development of immunodeficient mice for human tissue engraftment.
- Discussion of current engraftment techniques used in creating humanized mouse models.
- Analysis of studies utilizing humanized mouse models to investigate bacterial pathogenesis.
Main Results:
- Humanized mouse models demonstrate enhanced susceptibility to bacterial infections.
- These models more accurately recapitulate human disease phenotypes, such as granuloma formation.
- Humanized models have elucidated critical human immune responses to pathogens like Salmonella enterica serovar Typhi, Mycobacterium tuberculosis, and Staphylococcus aureus.
Conclusions:
- Humanized mouse models represent a significant advancement in infectious disease research.
- These models offer a more clinically relevant platform for evaluating novel therapeutics and vaccines.
- Further development and application of humanized mouse models are essential for combating bacterial infections and antimicrobial resistance.
