As reported, Stat2–/– and Ifnar–/– mice all sacrificed 4–8 days p.i. with weight loss, leukocytopenia, and thrombocytopenia in SFTSV (YG-1) lethal challenge, and variation trends and amplitudes of parameters between the two groups were highly consistent (Yoshikawa et al., 2019). This evidence concerns the gene STAT2 and Thrombocytopenia.
