Cai and coworkers, in fact, found that the amino acid transporter light chain L system (LAT1) and TSPO are both overexpressed in glioblastoma preclinical models but the LAT1 expression was restricted to tumor cells, while TSPO was also expressed on microglia, tumor-associated macrophages, endothelial cells, and pericytes [37]. The gene discussed is TSPO; the disease is neoplasm.
