Lymphocyte Activation Gene

Pathologic alpha-synuclein (alpha-syn) spreads from cell-to-cell, in part, through binding to the lymphocyte-activation gene 3 (Lag3). Here we report that amyloid beta precursor-like protein 1 (Aplp1) forms a complex with Lag3 that facilitates the binding, internalization, transmission, and toxicity of pathologic alpha-syn. Deletion of both Aplp1 and Lag3 eliminates the loss of dopaminergic neurons and the accompanying behavioral deficits induced by alpha-syn preformed fibrils (PFF). Anti-Lag3 prevents the internalization of alpha-syn PFF by disrupting the interaction of Aplp1 and Lag3, and blocks the neurodegeneration induced by alpha-syn PFF in vivo. The identification of Aplp1 and the interplay with Lag3 for alpha-syn PFF induced pathology advances our understanding of the molecular mechanism of cell-to-cell transmission of pathologic alpha-syn and provides additional targets for therapeutic strategies aimed at preventing neurodegeneration in Parkinson disease and related alpha-synucleinopathies.
