Fig. 2. TSPO ligands have no cytotoxic effects on microglia and astrocytes. (A) The table presents the class, name (and alternative name) and chemical structure of TSPO ligands. Microglia (B) and astrocytes (C) were treated with 50 µM of etifoxine, FGIN-1-27, PK11195, Ro5-4864, or XBD-173 for 24 h, and cell death assay was performed to assess the cytotoxicity of the TSPO ligands.
