Quantification of TREM1 PET tracer signal (saline ipsilateral, 2.1 6 0.45; saline contra- lateral, 2.1 6 0.33; isotype control ipsilateral, 1.9 6 0.29; isotype control contralateral, 1.8 6 0.35; TREM1 knockout ipsilateral, 3.1 6 0.57; TREM1 knockout contralateral, 2.8 6 0.97; day 7 6-hydrox- ydopamine ipsilateral, 2.7 6 0.45; day 7 6-hydroxydopamine contralateral, 2.4 6 0.48; day 14 6-hydroxydopamine ipsilateral, 2.7 6 0.23; day 14 6-hydroxydopamine contralateral, 2.2 6 0.43), ex vivo autoradiography (saline, 1.1 6 0.07; isotype control, 1.7 6 1.12; TREM1 knockout, 1.0 6 0.17; day 7 6-hydroxydopamine, 2.2 6 1.07; day 14 6-hydroxydopamine, 3.3 6 0.32), and g-counting quantification (brain: saline, 0.1 6 0.03; isotype control, 0.1 6 0.02; TREM1 knockout, 0.15 6 0.04; day 7 6-hydroxydopamine, 0.16 6 0.04; day 14 6-hydroxydopamine, 0.13 6 0.01; spleen: saline, 4.8 6 0.74; isotype control, 3.3 6 1.2; TREM1 knockout, 3.5 6 1.82; day 7 6-hydroxydopamine, 5.4 6 0.91; day 14 6-hydroxydopamine, 4.3 6 1.32) in saline, isotype control, and 6-hydroxydop- amine mice. All groups were compared with saline control (significance denoted by *); day 7 6-hydroxydopamine and isotype control were compared (significance denoted by #) as well as day 7 6-hydroxydopamine and TREM1 knockout (significance denoted by 1).
