FK506 augments activation-induced programmed cell death of T lymphocytes in vivo.

Abstract

FK506 is an immunosuppressive drug that inhibits T cell receptor-mediated signal transduction. This drug can induce immunological tolerance in allograft recipients. In this study, we investigated the in vivo effects of FK506 on T cell receptor-mediated apoptosis induction. Injection of anti-CD3 antibody (Ab) in mice resulted in the elimination of CD4+ CD8+ thymocytes by DNA fragmentation. FK506 treatment significantly augmented thymic apoptosis induced by in vivo anti-CD3 Ab administration. Increased thymic apoptosis resulted in the disappearance of CD4+ CD8+ thymocytes after anti-CD3 Ab/FK506 treatment. DNA fragmentation triggered by FK506 was induced exclusively in antigen-stimulated T cells, since enhanced DNA fragmentation induced by in vivo staphylococcal enterotoxin B (SEB) injection was confirmed in SEB-reactive V beta 8+ thymocytes but not in SEB-nonreactive V beta 6+ thymocytes. In addition to thymocytes, mature peripheral T cells also die by activation-induced programmed cell death. A similar effect of FK506 on activation-induced programmed cell death was observed in SEB-activated peripheral spleen T cells. In contrast, cyclosporin A treatment did not enhance activation-induced programmed cell death of thymocytes and peripheral T cells. Apoptosis is required for the generation and maintenance of self-tolerance in the immune system. Our findings suggest that FK506-triggered apoptosis after elimination of antigen-activated T cells may represent a potential mechanism of the immunological tolerance achieved by FK506 treatment.

Citation information
This citation data is accumulated from CrossRef, which receives citation information from participating publishers, including this journal. Not all publishers participate in CrossRef, so this information is not comprehensive. Additionally, data may not reflect the most current citations to this article, and the data may differ from citation information available from other sources (for example, Google Scholar, Web of Science, and Scopus).
