Animal models for exploring Chagas disease pathogenesis and supporting drug discovery

Area of Science:

• * Parasitology and Tropical Medicine
• * Immunology and Disease Pathogenesis
• * Drug Discovery and Development

Background:

• * Infections with *Trypanosoma cruzi* cause Chagas disease, leading to severe cardiac and digestive issues in 30-40% of cases.
• * The long incubation period and variable outcomes of Chagas disease in humans limit direct experimental study.
• * Predictive animal models are essential for understanding this complex parasitic infection.

Purpose of the Study:

• * To provide an overview of the animal models utilized in Chagas disease research.
• * To highlight the significant impact of these models on understanding *Trypanosoma cruzi* biology and disease.
• * To demonstrate how animal models facilitate global drug discovery for Chagas disease.

Main Methods:

• * Review and synthesis of existing literature on animal models for Chagas disease.
• * Analysis of contributions from animal model studies to parasite biology and immunology.
• * Illustration of the role of animal models in informing drug discovery pipelines.

Main Results:

• * Animal models have been instrumental in advancing knowledge of *Trypanosoma cruzi* infection dynamics.
• * These models have elucidated key aspects of immune responses and disease pathogenesis.
• * Data from animal models have directly informed and accelerated the development of new therapeutics.

Conclusions:

• * Predictive animal models are indispensable tools for Chagas disease research.
• * Continued use and development of animal models are vital for combating *Trypanosoma cruzi* infections.
• * Animal models provide a critical foundation for developing effective treatments and interventions for Chagas disease.
