Additionally, the miR-3473b targets the triggering receptor expressed on myeloid cells 2 (TREM2) and Unc-51 like autophagy activating kinase 1 (ULK1) to regulate the inflammatory response, such as the secretion of TNF-α and IL-1β, in Parkinson's disease [39]. This evidence concerns the gene TREM2 and Parkinson disease.
