By investigating 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, Shohat et al. [23] found that AS101 [24] 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, suggesting that IL-2R may have an immunosuppressive role. Here, IL5 is linked to mycosis fungoides.
