Figure Lengend Snippet: Figure 3. MAVS signaling mediates sensing of inactivated rotavirus dsRNA in intestinal epithelial cells (A–D) Human ileal enteroids cultured in transwells were stimulated with infectious RRV strain (MOI = 100), equivalent particle numbers of inactivated RRV, or recombinant human IFN-l3 protein (1 mg/mL) for 24 h. The mRNA levels of IFNL3 (A), ISG15 (C), and rotavirus NSP5 (D) were assessed by RT-qPCR, and levels of secreted IFN-l (B) were quantified by ELISA. (E) WT, RIG-I KO, MDA5 KO, RIG-I/MDA5 DKO, and MAVS KO HT-29 cells were inoculated with infectious RRV (MOI = 3) or equivalent particle numbers of inactivated rotavirus. IFNL3 transcript levels were assessed by RT-qPCR. (F) 5-day-old Mavsfl/fland Mavsfl/flAlpi-CreERT2 C57BL/6J mice were orally inoculated with inactivated RRV (107 PFU equivalent per mouse), and diarrhea occurrence was monitored from 0 to 9 dpi.
