Figure 6 .
Immunohistochemical staining of anti-CD80 or CD86 antibody on cultured renal cortical epithelial cells (HRCE) cells (×180). Without cytokine stimulation, CD80 (A) expression was not seen on HRCE and a few CD86 positive cells were seen (C). CD80 expression was not induced by interferon γ (IFNγ) (B). Many HRCE cells stimulated by 100 U/ml IFNγ for 24 hours showed only CD86 (D) expression.
