Comparing 2 hypotheses side-by-side
SLC17A7 (also known as VGLUT1, vesicular glutamate transporter 1) shows significant downregulation (log2FC = -1.7) in the SEA-AD dataset, specifically in layer 3 and layer 5 excitatory neurons of the middle temporal gyrus. This reduction in the primary vesicular glutamate transporter marks early excitatory neuron vulnerability in Alzheimer's disease and points to synaptic transmission failure as a proximal cause of cognitive decline. ## Molecular Function of SLC17A7/VGLUT1 VGLUT1 is a transmem
# Layer V excitatory neurons show selectively enhanced vulnerability through dysregulated calcium signaling ## Overview Cortical layer V excitatory neurons, particularly those of the extratelencephalic (ET) projection subtype, represent a functionally specialized population characterized by large soma size, extensive axonal projections to subcortical targets, and high metabolic demands. The hypothesis that these neurons exhibit selectively enhanced vulnerability in Alzheimer's disease (AD) thr
