CD80 and cancer: From this analysis, it was demonstrated that autologous cancer vaccines increased MHC-II surface expression ranging from 20.0-60.4% on single-stained cells (Fig. 2a-b), CD80 surface expression ranging from 23.7–45.9% on single-stained cells (Fig. 2c-d), and MHC-II/CD80 surface expression ranging from 7.2–20.1% on double-stained cells (Fig. 2e-f).
