  1. TREM2R47H showed no clear effect on amyloid β 42 accumulation in mice (knock-in on AppNL-F background).

    “Accumulation of amyloid β 42 and formation of dystrophic neurites were increased in Trem2 KO mice but not in Trem2 R47H KI mice at 18 or 24 months.”

Alzheimer’s risk variant mildly altered brain immune cells in mice

Experiments in Alzheimer’s-model mice aged 18 or 24 months found that a risk variant had different effects from complete loss of the gene.Experiments in Alzheimer’s-model mice aged 18 or 24 months found that a risk variant had different effects from complete loss of the gene.
