title = " Secreted amyloid-b precursor protein functions as a GABA B R1a ligand to modulate synaptic transmission ",
abstract = " Amyloid-b precursor protein (APP) is central to the pathogenesis of Alzheimer{\textquoteright}s disease, yet its physiological function remains unresolved. Accumulating evidence suggests that APP has a synaptic function mediated by an unidentified receptor for secreted APP (sAPP). Here we show that the sAPP extension domain directly bound the sushi 1 domain specific to the g-aminobutyric acid type B receptor subunit 1a (GABA B R1a). sAPP-GABA B R1a binding suppressed synaptic transmission and enhanced short-term facilitation in mouse hippocampal synapses via inhibition of synaptic vesicle release. A 17–amino acid peptide corresponding to the GABA B R1a binding region within APP suppressed in vivo spontaneous neuronal activity in the hippocampus of anesthetized Thy1-GCaMP6s mice. Our findings identify GABA B R1a as a synaptic receptor for sAPP and reveal a physiological role for sAPP in regulating GABA B R1a function to modulate synaptic transmission.",
