Therapeutic modulation of TREM2-dependent microglial function might provide an additional strategy to slow the progression of Alzheimer’s disease. Although studies in animal models suggest that TREM2 is protective against Alzheimer’s pathology, its effect on tau pathology and its potential beneficial role in people with Alzheimer’s disease is still unclear. Our aim was to study associations between the dynamics of soluble TREM2, as a biomarker of TREM2 signalling, and amyloid β (Aβ) deposition, tau-related pathology, neuroimaging markers, and cognitive decline, during the progression of autosomal dominant Alzheimer’s disease.
