Role of CD80 in stimulating T lymphocyte activation

Figure 1 Flow cytometric analysis of CD80 expression in cells of different groups. A: HepG2/mock; B: negative control; C: HepG2/hCD80; D: positive control.

Figure 2 RT-PCR analysis of CD80 mRNA expression in different group cells. M: DL1000 molecule marker; lane 1: β-action; lane 2: positive control; lane 3: HepG2/mock; lane 4: HepG2/hCD80 cells.

Figure 4 CD25 expression on T cells stimulated by HepG2/mock cells or HepG2/hCD80 cells. A: T cells stimulated by HepG2/hCD80 cells; B: T cells stimulated by HepG2/mock cells. Shaded histograms show reactivity with the isotype control. Each figure is representative of at least three experiments.
