In contrast, no differences in the levels of GDP dissociation inhibitor 1, neuronal pentraxin 1, neurofilament light chain (NEFL), phosphatidylethanolamine binding protein 1, SYT7 or postsynaptic metabotropic glutamate receptor subtype 5 were detected between AD patients and NCs (Fig. S7). This evidence concerns the gene NPTX1 and Alzheimer disease.
