In about 3-4% of patients, the integrated proviral DNA or the virally encoded proteins cause CD4 cell or T-helper lymphocyte lymphoproliferative disease that may result in adult T-cell leukemia (ATL).
9) Cyclosporine and tacrolimus have inhibitory effects on T-helper lymphocyte production of IL-2, IL-2 receptors (IL-2r), and interferon gamma (IFN-[gamma]) as well as to a lesser degree on the production of other cytokines (IL-3, 4 and 5, TNF-[alpha] and [beta]) that lead to altered T-lymphocyte and B-lymphocyte function.
We cannot exclude also important role of the functional disorders on the part of such effector cells, as macrophages, participating in processing of antigen and its presentation to naive T-helper lymphocyte, since, exactly at this stage the chain of regulating events occur, defining direction of immune response (Yarilin, 1999).

Interleukin-9 (IL-9) is an attractive therapeutic target because the multifunctional cytokine has been shown in experimental models to increase airway inflammation, airway obstruction, airway hyperresponsiveness, mucin production, mast cell generation, and T-helper lymphocyte type 2 (Th2 lymphocyte) and eosinophil accumulation, explained Dr.
