DPT and escherichia coli infection: To further explore the physiological function of the Relish/lncRNA-CR33942/AMPs regulatory axis, we monitored the dynamic expression of Relish, lncRNA-CR33942, Dpt, and AttA in wild-type flies (w1118) at different time points (0, 3, 6, 12, 24, and 48 h) after E. coli infection.
