This invention refers to the field of
human medicine and specifically to the diagnosis / prognosis of the responsiveness to a
cytokine targeting
drug (Cy TD) or an anti-inflammatory biological
drug treatment of a subject suffering from an inflammatory
disease. More precisely, the present invention concerns a method for the in vitrodiagnosis / prognosis of a Cy TD or an anti-inflammatory biological
drug responsive or non-responsive
phenotype, comprising: (a) determining from a subject biological sample an expression profile comprising the
gene MKNK1; or of the genes MKNK1 and GNLY; or of the genes MKNK1, TBX21 and TGFBR3; or of the genes MKNK1, GNLY, and ADI1; or of the genes MKNK1, GNLY, ADI1, and IL1B; or of the genes MKNK1, GNLY, ADI1, IL1B, and IL1R1; or of the genes MKNK1, PRF1, TBX21, TGFBR3, IFNGR2, FYN, IL1B and CFLAR; or of the genes MKNK1, PRF1, TBX21, TGFBR3, IFNGR2, FYN, IL1B, CFLAR, MAPK14 and GNLY; or of the genes MKNK1, PRF1, TBX21, TGFBR3, IFNGR2, FYN, IL1B, CFLAR, CD14 and TGFBR2; or of the genes MKNK1, IFNGR2, IL1B, MAPK14, GNLY, and CD14; or of the genes MKNK1, PRF1, TBX21, TGFBR3, IFNGR2, IL1B, CFLAR, MAPK14, GNLY, CD14 and TGFBR2; or of all the 46 genes of following Tables 2, 3 and 4; or Equivalent Expression Profile thereof, provided that, in said Equivalent Expression Profile thereof, MKNK1 is not replaced by
gene S 100A8 nor
gene MAPK14, and (ii) optionally one or more
housekeeping gene(s), (b) comparing the obtained expression profile with at least one reference expression profile, and (c) determining the responsive or non-responsive
phenotype from said comparison. The present invention also relates to kits and
nucleic acid microarrays for performing said method. The present invention also relates to methods of treatment of inflammatory
disease-suffering patients.
