| abstractText | The molecular alterations that induce tau pathology in Alzheimer disease (AD) are not known, particularly whether this is an amyloid-beta (Abeta)-dependent or -independent event. We addressed this issue in the 3xTg-AD mice using both genetic and immunological approaches and show that a selective decrease in Abeta(42) markedly delays the progression of tau pathology. The mechanism underlying this effect involves alterations in the levels of C terminus of heat shock protein70-interacting protein (CHIP) as we show that Abeta accumulation decreases CHIP expression and increases tau levels. We show that the Abeta-induced effects on tau were rescued by restoring CHIP levels. Our findings have profound clinical implications as they indicate that preventing Abeta accumulation will significantly alter AD progression. These data highlight the critical role CHIP plays as a link between Abeta and tau and identify CHIP as a new potential target not only for AD but for other neurodegenerative disorders characterized by tau accumulation. |
