To examine the effect of anti-α3 subunit autoantibody on cell-surface nAChRs, we established human embryonic kidney 293 cells stably co-expressing α3 and β4 subunits. Upon incubation with seropositive patient's serum, this cell line showed co-accumulation of patient's IgG and α3 subunits in the cytoplasm. These data support the hypothesis that anti-α3 subunit autoantibody induces internalization of cell-surface nAChRs and thereby impairs synaptic transmission. © 2012 Elsevier B.V.
