Semiquantitative induction of immune-responsive genes in Galleria after challenge with heat-killed bacteria. The transcription levels of defensin 1, defensin 2, IMPI, lysozyme, and cecropin D following injection of heat-killed L. monocytogenes were determined by quantitative real time RT-PCR analysis and are shown relative to the expression levels of mock-injected animals. Values were normalized on expression levels of the housekeeping gene 18S and represent the results of three independent determinations ± SD.
