NLRP3 and psoriasis: To explore the correlation between cuproptosis genes in patients with psoriasis, we used linear regression analysis and found that the expression levels of FDX1, SLC31A1, DLD, LIAS, LIPT2, and LIPT1 were highly positively correlated with GCSH (Figures 2A–F), whereas the expression levels of ATP7B and NLRP3 showed a negative correlation (Figures 2G, H).
