It is involved in the following cell signaling pathways, which are documented to be relevant in psoriasis pathogenesis and are mediators of neurodegenerative processes at the same time: NF-κB pathway, MAPK, JAK/STAT, and PI3K/Akt/mTOR (Kempuraj et al., 2016; Lin and Huang, 2016; Venkatesha and Moudgil, 2016).
