Figure 4.

Double staining immunofluorescence of VISTA (red signals) and CD68, CD4 and CD8 (green signals) with counterstaining of the nuclei with DAPI (blue signals). The photos (a-c) represent one double staining each with different fluorescence filters. (a) VISTA and CD68 show a coexpression representing myeloid origin; (b) VISTA and CD4 show a strong coexpression within the VISTA positive TILs; (c) No correlation of VISTA and CD8 was seen.
