CD93 and infection: In C1qR-RNAi crayfish, theexpression levels of VP28 (1.93-fold, Fig.3F) and the relative level of WSSV copies (21.83-fold, Fig. 3G) increased after 24 h WSSV infection.Significant reductions in VP28 expression levels and the relative level of WSSVcopies were observed in rC1qR-injected crayfish after WSSV infection (Fig. 3H and I).
