Background:

Cryptococcus is an emerging fungal pathogen with high mortality and limited treatment options.
Understanding host-pathogen interactions is vital for cryptococcal disease management.
Murine models offer a valuable platform to study cryptococcal pathogenesis, overcoming limitations of human studies.

Purpose of the Study:

To establish and validate a murine model of pulmonary cryptococcal infection via intranasal inhalation.
To provide detailed protocols for assessing host immune response and disease progression.
To facilitate research into fungal virulence and host-pathogen dynamics for improved therapeutic strategies.

Main Methods:

Establishing a murine model of pulmonary cryptococcal infection through intranasal inhalation.
Assessing the pulmonary immune response, including gene expression via real-time PCR.
Enumerating survival rates and quantifying fungal burden in organs.

Main Results:

The described protocols enable the establishment of a reproducible murine model for cryptococcal infection.
The model allows for comprehensive assessment of immune responses and disease progression.
This methodology supports the evaluation of fungal virulence and host-pathogen interactions.

Conclusions:

The intranasal inhalation murine model is a valuable tool for studying Cryptococcus infection and pathogenesis.
This model system is essential for developing effective antifungal therapies and treatment strategies.
Further research using this model can elucidate critical aspects of cryptococcal disease outcomes.
