摘要: Interleukin-18 (IL-18), otherwise known as interferon-gamma-inducing factor (IGIF), is one of several well characterized and important cytokines that contribute to host defenses. The complementary DNA (cDNA) mature human interleukin-18 gene (hIL-18) was fused with the signal peptide rice amylase 1A (Ramy1A) introduced into plant expression vector under control a duplicated CaMV 355 promoter. recombinant plasmid transformed tobacco (Nicotiana tabacum L. cv Havana) using theAgrobacterium-mediated transformation method. integration hIL-18 genome transgenic plants confirmed by polymerase chain reaction (PCR) amplification its observed in suspension cells were derived from callus Northern blot analysis. protein detected extracts medium culture immunoblot Based upon enzyme-linked immunosorbant assay (ELISA) results, level approximated 166 μg/L medium. Bioassay results induction interferon-γ KG-1 cell line indicated secreted bioactive.
