Neutrophil infiltration and tortuous telangiectasia are pathological features of psoriasis (Chau et al., 2017), and MMP-9 can decompose a 62-amino acid peptide from IL-8 (CXCL8/CL8) to increase the chemotactic activity of neutrophils (Mieke et al., 2018). The gene discussed is MMP9; the disease is telangiectasis.
