TSPO and amyloidosis: Dual tracer μPET imaging of Aβ and TSPO was recently established in the transgenic PS2APP mouse model (Brendel et al., 2016), a strain that is known for a strong inflammatory component besides the remarkable age-dependent amyloidosis (Richards et al., 2003; Ozmen et al., 2009); the dual tracer approach revealed associations of neuroinflammation and amyloidosis.
