🧪 Overview

Somatostatin interneurons show selective vulnerability through neprilysin-independent Aβ42 accumulation. SST+ interneurons display reduced SST, CALB1, and PVALB expression with intracellular Aβ42 accumulation despite normal MME (neprilysin) levels, indicating impaired trafficking rather than enzymatic degradation failure.
