IL17A and Parkinson disease: A study using human induced pluripotent stem cell (iPSC)-based PD model showed increased neuronal death induced by upregulation of IL-17 receptor (IL-17R) and NF-κB activation, and the neuronal death could be rescued by blockage of IL-17 or IL-17R or the use of an IL-17 antibody (Sommer et al., 2018).
