Here's why:
* Genetic Similarity: Mice share approximately 90% of their genes with humans, making them a highly relevant model for studying human biology.
* Well-established Genetics: Extensive genetic tools and resources exist for mice, enabling researchers to manipulate and study specific genes related to immune function.
* Immune System Similarity: Mice have a complex immune system that mirrors many aspects of the human immune system, including T cells, B cells, macrophages, and other immune cells.
* Ease of Breeding and Manipulation: Mice are relatively easy to breed and maintain in laboratory settings, making them ideal for controlled experiments.
* Availability of Immune Deficiency Models: Various mouse strains with specific immune deficiencies are available, which are valuable for studying specific immune components and pathways.
While mice are the most widely used, other model organisms are also employed in immunology research, including:
* Zebrafish: Used for studying development and innate immunity due to their transparency and genetic tractability.
* Drosophila melanogaster (fruit fly): Provides insights into innate immunity and signaling pathways.
* Caenorhabditis elegans (roundworm): Useful for understanding basic principles of immunity, particularly in the context of aging and stress responses.
However, mice remain the gold standard for studying human immunity due to their genetic similarity, robust immune system, and extensive research tools available.
