Fig. 1: Higher sTREM2 levels are associated with lower amyloid and tau accumulation as well as cognitive decline in individuals with underlying AD pathology.

a–d, Results of the linear mixed effect models showing that nondemented A+ individuals with higher baseline sTREM2 levels show less longitudinal accumulation of global amyloid (n = 115) (a), whereas A+T+ individuals show less tau aggregates in III–IV (b) and V–VI (c) Braak regions (n = 38) as well as a decline in the MMSE test scores (n = 53) (d). Amyloid (A+) and tau (T+) pathology were assessed using PET. All variables were z-transformed (Z), and the results were adjusted for multiple comparisons using FDR corrections (two tailed, q < 0.05). Data are presented as mean ± s.e.m.
