TSPO and Lewy body dementia: The evidence for inflammation and immune cell dysregulation in human Lewy body disease is partly based on imaging of translocator protein 18kDa (TSPO) (reviewed in [143, 213, 243, 244, 276]), but it has been difficult to ascertain if the net impact of immune cell function in Lewy body disease is helpful or harmful (it may also vary across genetically diverse human subjects).
