Mouse Models for Mycobacterium tuberculosis Pathogenesis: Show and Do Not Tell

Area of Science:

• * Biomedical research
• * Infectious disease modeling
• * Tuberculosis research

Background:

• * Animal models have been crucial in scientific discovery since ancient Greece.
• * Mice are widely used models, particularly for infectious disease research.
• * Mice have provided significant data on tuberculosis (TB) infection dynamics.

Purpose of the Study:

• * To highlight the utility of mouse models in understanding tuberculosis.
• * To review key host and bacterial factors studied in mouse models of TB.
• * To emphasize the role of these studies in advancing TB diagnostics, treatments, and prevention.

Main Methods:

• * Review of existing literature on mouse models in tuberculosis research.
• * Analysis of host factors such as aging and sexual dimorphism.
• * Consideration of bacterial factors and infection routes in mouse models.

Main Results:

• * Mouse models have elucidated host susceptibility traits for Mycobacterium tuberculosis infection.
• * Studies have explored the impact of genetic differences, immunity, and infection routes in mice.
• * Data from mouse models inform understanding of TB pathogenesis and host-pathogen interactions.

Conclusions:

• * Mouse models are indispensable for advancing tuberculosis research.
• * Continued investigation of host and bacterial traits in mice will drive innovation in TB control.
• * Despite some limitations, mouse models remain vital for developing new tools for tuberculosis diagnosis, treatment, and prevention.
