Cytokine profile of patients with mycosis fungoides and the immunomodulatory effect of AS101.
Cytokines are known to play a major role in the pathogenesis of mycosis fungoides, a cutaneous malignant neoplasm of CD 4 T cells. In the present study, we investigated the effect of AS101, a tellurium-based compound with immunomodulating properties, on the pattern of lymphokine production by peripheral blood mononuclear cells (PBMCs) from patients with mycosis fungoides. PBMCs were isolated from 35 patients with mycosis fungoides stage IA and IB before initiation of treatment and from 20 healthy sex and age-matched controls. Unstimulated and phytohaemagglutinin-stimulated PBMCs were tested with and without the addition of AS101. The production of interferon-gamma, interleukin 2 (IL-2), IL-2 receptor ( IL-2R), interleukin 5 (IL-5) and interleukin 10 (IL-10) was determined by enzyme-linked immunosorbent assays. The effects of AS-101 on mycosis fungoides PBMCs were compared to those of healthy donor PBMCs. Significantly higher levels of IL-2R, IL-5 and IL-10 and significantly lower levels of interferon-gamma were found in the patients compared to the controls. There was no significant difference between the groups in the production of IL-2. AS101 inhibited the production of IL-2R, IL-5 and IL-10 and induced a significant increase in IL-2 levels in the mycosis fungoides PBMCs. These findings may have important clinical implications for the possible therapeutic benefit of AS101 in mycosis fungoides.[1]References
