Our aim was to explore data on the levels of protein-complexed DNAs neutrophil elastase–DNA (NE-DNA) and myeloperoxidase–DNA (MPO-DNA), citrullinated histones (citH2, citH3, citH4), and NET-degrading enzyme DNase I in the serum of psoriatic patients with varying severities of clinical symptoms assessed with the Psoriasis Area Severity Index (PASI), Body Surface Area (BSA), and Dermatology Life Quality Index (DLQI) scores. Here, ELANE is linked to psoriasis.
