Athymic mice are missing what organ? The missing organ is responsible for providing what type of cell to the body? What is an advantage for researchers to use athymic mice?
They are missing their thymus, which produces T cells. Because they are missing T cells, they aren’t able to mount a good immune response to pathogens. The allows the pathogen to be studied without an immune interference.
