- AB Cyclosporine A (CsA) is a potent immunosuppressive drug which interferes
- in vitro and in vivo with T-cell function. CsA has been shown to arrest
- T-cell maturation intrathymically and to inhibit T-cell proliferation.
- In this study, we demonstrate that CsA induces apoptosis in the canine
- CD4+ CD8- T-lymphocyte cell line 401 in a dose- and time-dependent
- fashion. Similar results could also be obtained from human peripheral
- blood lymphocytes. Apoptosis is observed within 4 hours after CsA
- application and is not prevented by excessive addition of ConA
- supernatant as a source of interleukins. The induction of apoptosis in
- CD4+ T lymphocytes suggests a possible treatment option for human
- immunodeficiency virus (HIV) infections, since the major target
- population for the HIV would be ablated at short term. A
- computer-simulated analysis with the Cybermouse HIV model confirmed that
- the virus would eventually disappear and HIV-infected macrophages would
- also be substantially reduced if CsA were given in combination with
- drugs which block viral replication (3'-azido 3'-deoxythymidine or
- 2',3'-dideoxycytidine). This treatment scenario could be applied under
- controlled conditions and with supportive patient care. A further review
- of the literature also suggests the positive impact of CsA treatment on
- the progression and outcome of AIDS-related mortality.
