Notably, in line with previously reported up-regulation of TSPO in infiltrating immune cells in drug-resistant mTLE (64), in the myeloid tumor microenvironment (65), and in inflammatory processes as cerebral vasculitis (66), Iba-1+ phagocytes are the predominant source of TSPO expression in human brain specimen of patients with presumably CD8 T cell–mediated ALE and in our mouse model of definite CD8 T cell–mediated ALE. The gene discussed is AIF1; the disease is myeloid neoplasm.
