We previously demonstrated that the Alzheimer’s disease (AD)-like model mice, Tg2576, housed at a high ambient temperature of 30 °C for 13 months, exhibited increased body temperature, which increased amyloid-β (Aβ) levels and tau stability, leading to tau phosphorylation and ultimately inducing memory impairment. The gene discussed is MAPT; the disease is early-onset autosomal dominant Alzheimer disease.
