pubmed-article:19204148 | pubmed:abstractText | Junctional adhesion molecule (JAM)-C is an Ig superfamily protein, which is involved in the regulation of various inflammatory and vascular events such as transendothelial leukocyte migration. JAM-C is expressed highly on the surface of endothelial cells and platelets, whereas expression in T lymphocytes is not well studied. To investigate the specific gene regulation of JAM-C in T lymphocytes, we determined JAM-C expression in quiescent and activated human T cells. Treatment with the polyclonal T cell activator PHA increased surface and total JAM-C expression in T cells time- and dose-dependently, as determined by flow cytometry and immunoblot analysis. In contrast, no up-regulation of JAM-A in activated T cells was detectable. The highest level of JAM-C up-regulation by PHA was observed in CD3(+)forkhead box P3(+) and CD4(+)CD25(high) T cells. Moreover, TCR activation with combined anti-CD3 and anti-CD28 stimulation induced JAM-C expression in T cells. JAM-C induction occurred at the mRNA level, suggesting a transcriptional regulatory mechanism of JAM-C expression. Accordingly, we studied the regulation of the human JAM-C gene promoter in transiently transfected T cells. Luciferase activity of a JAM-C promoter gene construct with three potential consensus sites for the transcription factor NFAT was induced markedly in activated T cells. Finally, pretreatment with two pharmacological inhibitors of calcineurin, cyclosporin A, and FK-506, but not with MAPK inhibitors, blocked JAM-C induction in activated T cells. In summary, JAM-C is up-regulated in activated human T lymphocytes via a transcriptional mechanism, suggesting a potential role of JAM-C in T cell functions. | lld:pubmed |
