Abstract

Several experimental conditions were used in this study to evaluate the in vitro effects of I5-deoxyspergualin on the function of T lymphocytes, B lymphocytes and monocytes from healthy subjects and patients suffering from systemic lupus erythematosus. Whilst the secretion of polyclonal immunoglobulin (Ig) M and IgG from the B lymphocytes of the healthy subjects was diminished by 15-deoxyspergualin, neither the proliferative response of normal T and B cells to mitogenic stimulation nor the cytokine secretory capacity of these cells (e.g. interleukin-2, -4, -6 and γ-interferon) and monocytes (e.g. interleukin-1β and -6) were affected by the drug. In contrast, on the mononuclear cells obtained from the lupus patients not only did 15-deoxyspergualin inhibit the spontaneous production of polyclonal and anti-DNA IgG antibodies but also suppressed interleukin-1β secretion from the monocytes. Other functional responses of T and B cells and monocytes from lupus patients, including mitogenic activation and cytokine secretion, were not altered by the drug. These data suggest that 15-deoxyspergualin possesses a novel mechanism of pharmacological immunosuppression apparently different from that of other immunosuppressants, such as cyclosporin A, FK506 and corticosteroids, that seems to be primarily displayed at the level of autoreactive B cells and monocytes.
