Immunoreactivity for c-REL of germinal center (GC) and infiltrating B cells of hyperplastic myasthenia gravis (MG) thymuses. Double immunofluorescence stainings of normal thymus (upper panels) and hyperplastic MG thymic sections from untreated (MG) and corticosteroid-treated (MG-Cortico) patients (middle and lower panels) for c-REL (red), alone (right panels) or in combination with CD20 (green) (left panels), marker of B cells. Blue staining shows DAPI-positive nuclei. Magnification bars: 50 μm in all panels.
