TGF-β was discovered as a tumor product that promoted the survival of cells.

Some regulatory T cells produce TGF-β, and the same cells may also produce IL-10, which also has immunosuppressive activities.

TGF-β inhibits the proliferation and effector functions of T cells and the activation of macrophages. Acts on neutrophils and endothelial cells to counteract the effects of pro-inflammatory cytokines.

TGF-β stimulates production of IgA by inducing B cells to switch to this isotype.
