Modulation of the expression of miRNA and genes involved in their processing in healthy donor neutrophils by inflammatory components - in vitro effects of TCZ and IFX in RA active neutrophils. (A) Serum and synovial levels of TNF-α and IL-6 (40 HD-serum, 40 RA-serum and 40 RA-SF). a: significant differences vs. HD serum P<0.05; b: significant differences vs. RA serum P<0.05. (B) Expression of miRNA and genes involved in their biogenesis machinery in HD neutrophils treated with TNF-a. (C) Expression of miRNA and genes involved in their biogenesis machinery in HD neutrophils treated with IL-6. (D) Expression of miRNA and genes involved in their processing in RA active neutrophils treated in vitro with TCZ or IFX. (E) Gene expression of putative mRNA targets of the validated miRNA in RA active neutrophils treated in vitro with TCZ or IFX. (F) Protein levels of putative mRNA targets of the validated miRNA in RA active neutrophils treated in vitro with TCZ or IFX. miRNA: microRNA; HD: healthy donor; TCZ: tocilizumab; IFX: infliximab; RA: rheumatoid arthritis; AGO-1: argonaute-1; AGO-2: argonaute-2; XPO-5: exportin-5; VEGFA: vascular endothelial growth factor; TNF-a: tumor necrosis factor-alpha; IL-1β: interleukin-1 beta; IL-8: interleukin-8; IL-6R: interleukin-6 receptor; STAT-3: signal transducer and activator of transcription 3; AKT: protein kinase B; Non-t: non-treated. Data are presented as mean ± standard error of the mean (SEM) of five independent experiments; a: significant differences respective non-treated P<0.05.
