U.S. researchers develop mouse models revealing COVID-19 infection

LOS ANGELES, Oct. 1 (Xinhua) -- U.S. researchers have developed six lines of humanized mice that can serve as valuable models for studying human cases of COVID-19, according to a newly published study.

These mouse models, developed by researchers at La Jolla Institute for Immunology, are important for COVID-19 research because their cells were engineered to include two important human molecules that are involved in SARS-CoV-2 infection of human cells -- and these humanized mice were generated on two different immunologic backgrounds, according to the study published Monday in eBioMedicine.
