Introduction:
The interleukin-12/23 (IL-12/23) signalling pathway plays an important role in the pathogenesis of psoriasis. In addition, even molecularly targeted therapy has been reported to lose adequate response to treatment.

Aim:
To determine the expression patterns of mRNAs and miRNAs related to IL-12/23 signalling pathways in the human keratinocyte culture exposed to liposaccharide A (LPS) and then adalimumab in comparison with untreated cells.

Material and methods:
Human, adult, low-Calcium, high-Temperature keratinocyte (HaCaT) cultures were exposed to 1 µg/ml LPS for 8 h, and then adalimumab was added to the cultures at a concentration of 8 µg/ml and incubated for 2, 8, and 24 h. We used mRNA and miRNA microarray, quantitative reverse transcription polymerase chain reaction, and enzyme-linked immunosorbent assay techniques.

Results:
STAT1, STAT3, STAT5, IL-6, IL-6R, SOCS3, and JAK3 genes differentiated HaCaT cultures with the drug from controls regardless of the time the cells were exposed to the drug. The addition of adalimumab to a culture previously exposed to LPS resulted in silencing of SOCS3 and IL-6 expression compared to the control, while for the other transcripts they were found to be overexpressed compared to the control culture. The assessment indicated the strongest connections between JAK3 and hsa-miR-373-5p (target score 96); SOCS3, STAT5, and hsa-miR-1827 (target score 96).

Conclusions:
Our study indicates that adalimumab has the strongest modulating effect on mRNA and miRNA expression of JAK/STAT and IL-6-dependent IL-12/23 pathways.
