The authors of this study proposed that this distinctive pattern of TSPO density change in late stage DLB cases may indicate microglia dystrophy.427 This is similar to the results of a previous study, which observed the microglia morphology by immunohistochemistry and found that in the late stage of DLB, there was low microglia density and microglia showed dystrophic phenotype.418. The gene discussed is TSPO; the disease is Lewy body dementia.
