How this Key Event works

Effects on T cell

NFAT/AP-1 complex might bind to the promoter or enhancer regions of the cytokine genes in T cells; therefore, productions of IL-2, IL-3, IL-4, IL-5, GM-CSF and other T-cell-derived cytokines after activation of T cells were reported to be suppressed by FK506 treatment in vitro and in vivo as the result of hindered nuclear translocation of NFAT. FK506 inhibited both IL-2 and IFN-γ mRNA expression in anti-CD3/PMA-activated cells. FK506 had suppressed the expression of IL-4 mRNA in the presence of either anti-CD3or PMA-activated cells after 5h of culture (Dumont et al. 1998).

Effects on B cell

In B-cells, stimulus passes through the B-cell receptor (BCR), increasing the concentration of calcium in the B-cell, leading to NFAT nuclear localization in the same manner as T-cells (Bhattacharyya et al.2011). Inhibition of calcineurin phosphatase activation by FK506 suppresses induction of TNF-α following anti-Ig or anti-CD40 antibody stimulation (Goldfeld et al. 1992, Goldfeld et al. 1994, Boussiotis et al. 1994).

Effects on dendritic cells

FK506 suppresses expression of IL-2R (CD25) and costimulatory molecules CD80 (B7.1)/CD40 in Langerhans cells.

Effects on natural killer (NK) cells and NKT cells

In human NK cells, FK506 suppresses IL-2 responsive proliferation and cytokine production as well as lowers cytotoxicity directed toward K562 tumor cells (Kim et al. 2010). FK506 suppresses IL-2 production of NKT cell line DN32.D3 induced by stimulus from phorbol 12-myristate 13-acetate (PMA)/calcium-ionophore (van Dieren et al. 2010).

How it is Measured or Detected

Suppression of mRNA levels of cytokines can be measured by RNase protection assay in vitro and ex vivo. Inhibition of IL-2, IL-3, IL-4, IL-5, GM-CSF, IFN-γ, TNF-α production and secretion are measurable by sandwich ELISA.

Evidence Supporting Taxonomic Applicability

In human peripheral blood mononuclear cells (PBMC), FK506 suppresses T-cell activation–induced production of IL-1β and TNF-α (Sakuma et al. 2000). It also suppresses production of cytokines such as IL-2, IL-3, IL-4, IL-5, IFN-γ, and GM-CSF, which is induced by CD2/CD3 or CD3/CD26 stimulation, at least as if not more strongly than steroids in human PBMC (Sakuma et al. 2001a). Moreover, it suppresses production of IL-2, IL-3, IL-4, IL-5, IL-6, IL-10, TNF-α, IFN-γ, and GM-CSF, which is induced by CD3/PMA stimulation in human PBMC (Dumont et al. 1998).
