Although STING-KO and RAW264.7 ISG cells had similar TNF-α gene expression upon infection, we found that parasite DNA transfection resulted in increased TNF-α gene expression in RAW264.7 ISG cells when compared with nontransfected control, which was not observed in STING-KO cells (Supplementary Figure S1B). The gene discussed is TNF; the disease is infection.
