TBK1 and ocular toxoplasmosis: Consistent with the above conclusion that GRA4 could promote anti‐T. gondii immunity in an IFN‐I dependent manner, we here also found ME49Δgra4 no longer exhibit stronger virulence, which was reflected by the weight loss, survival, and ocular toxoplasmosis, than ME49wt in the Tbk1‐slienced host (Figure S6C–E, Supporting Information).
