It was later found that TSPO targeted imaging could be utilized for the imaging of non-neuronal inflammatory diseases such as rheumatoid arthritis (RA), atherosclerosis, Takayasu arteritis (TAK), systemic lupus erythematosus (SLE), and GCA (88, 94, 98–100, 103, 106, 185, 190, 193). The gene discussed is TSPO; the disease is systemic lupus erythematosus.
