Therapeutic Strategies for SLE Involving Cytokines: Mechanism-Oriented Therapies Especially IFN-γ Targeting Gene Therapy

الملخص EN

Systemic lupus erythematosus (SLE: lupus) is a chronic complicated autoimmune disease and pathogenesis is still unclear.

However, key cytokines have been recognized.

Interferon (IFN)-γ and also IFNα/β are of particular importance.

Depending on the concept that lupus is a helper T(Th)1 disease and that dendritic cells (DCs) determine the direction of lupus, balance shift of Th1/Th2 and immunogenic/tolerogenic DCs is reviewed for therapy.

(IFN)-γ- and IFN-α/β-targeted (gene) therapies are introduced.

These consist of Th1/Th2 balance shift and elimination of IFN-γ and IFN-γ-related cytokines such as (interleukin)IL-12 and IL-18.

Other approaches include suppression of immunocompetent cells, normalization of abnormal T-cell function, costimulation blockade, B lymphocyte stimulator (Blys) blockade, and suppression of nephritic kidney inflammation.

Moreover, balance shift of IFN-α/β and tumor necrosis factor (TNF)-α together with regulatory T(Treg) cells are briefely introduced.

Clinical application will be discussed.
