Effect of co-culturing mature and immature DCs on lymphocyte cell surface makers (n=3). The percentage of CD3+CD4+ (A), CD3+ CD8+ (B), and CD3+CD4+/CD3+ CD8+ (C) cells is presented. Group A: immature DCs+LC; group B: immature DCs+LC+HepG2.2.15; group C: mature DCs+LC; group D: mature DCs+LC+HepG2.2.15. ap<0.05, group B vs. group A; bp<0.05, group D vs. group C; cp<0.05, group C vs. group A; dp<0.05, group D vs. group B.
