Title	SORL1 regulates APOE and CLU levels in human neurons
Description	SORL1 is implicated in the pathogenesis of Alzheimer’s disease (AD) through genetic studies. To interrogate the role(s) of SORL1 in human brain cells, SORL1 null iPSCs are differentiated to neuron, astrocyte, microglial, and endothelial cell fates. Loss of SORL1 leads to alterations in both overlapping and distinct pathways across cell types, with the greatest effects in neurons and astrocytes. SORL1 loss induces a neuron-specific reduction in APOE and CLU and altered lipid profiles. Enhancement of retromer-mediated trafficking rescues tau phenotypes observed in SORL1 null neurons but does not rescue APOE levels. Pathway analyses implicate TGF-β/SMAD signaling in SORL1 function, and modulating SMAD signaling in neurons alters APOE RNA levels in a SORL1-dependent manner. Analyses of iPSCs derived from a large cohort reveal a neuron-specific association between SORL1, APOE, and CLU levels, a finding validated in post-mortem brain. These studies provide a mechanistic link between strong genetic risk factors for AD.
