Since consumption of the Mediterranean diet is associated with
decreased MMP - 9 activity [30], researchers must once again attempt to decipher the extent to which dietary benefits might be intertwined with intestinal microbiota.
However, fibrillar Aß preparations lead to similar
decrease in
MMP as oligomeric Aß, suggesting that mitochondrial dysfunction is mediated by both species in contrast to defects in long - term potentiation (LTP) where only oligomeric Aß inhibits LTP [59].
