Interesting papers. It's quite amazing that a protein linked to enhanced memory performance can be linked to synaptic plasticity, and AMPAR trafficking. The study by Makuch et al. provides more evidence that AMPA-R trafficking is an important regulated process in memory formation. Given that the T allele may provide some protection against AD, it supports a role for defects in AMPAR trafficking in AD. In this context it would be nice to know how the T allele changes AMPAR trafficking in model systems.
