Exosome uptake by tonsil mononuclear cells, CD123/CD40 expression in tonsil tissue and EBER1 detection in skin tissues. (A) FACS analysis of tonsil mononuclear cells based on CD19, CD3, CD56, BDCA2, and CD123 surface markers. (B) PKH67-exosome uptake by CD123+/BDCA2+ pDCs and CD123−/BDCA2− tonsil cells. (C) Immunofluorescence staining for CD123 (red) and CD40 (green) on tonsil tissue sections reveals single CD40+ cells and CD123+ pDCs. Nuclei are stained with DAPI. (D) EBER1 in situ hybridization in SLE and inflamed skin tissues. EBV+ lymphoma tissue was used as positive control.
