Fig. 1From: Prokaryotic ribosomal RNA stimulates zebrafish embryonic innate immune systemDose-dependent increase in the expression levels of markers upon E. coli rRNA and LPS stimulations. E. coli rRNA (10–40 ng) a and LPS (10–40 ng) b were injected into zebrafish embryos at 30 hpf. At 6 hpi, the induced expression levels of il8, il1β, psmb9a and rpl38 were analyzed by PCR for the respective doses of stimulants. C Control (water)Back to article page
