[This contact-dependent mechanism of suppression has been shown most convincingly by CD4+CD25+ natural Treg cells employed in in vitro models of suppression, whereas cytokine-mediated suppression has been best established for peripheral adaptive Treg] cells in vivo. However, the adaptive Treg cell subset, although it suppresses in a cytokine-dependent manner, might still require direct cell-cell contact to initiate the suppressive cascade.

Figure 6: Two classes of regulatory T cells can be envisioned. a In this hypothetical model, the natural regulatory T (Treg) cells (blue) suppress immune response in a contact-dependent manner and function in general homeostasis to block the actions of autoimmune T cells (red) in noninflammatory settings. b The adaptive Treg cell subset enhances the robust nature of suppression in an inflammatory milieu. Importantly, adaptive Treg cells can develop either CD4+CD25+ natural Treg cells (blue striped) or by altering the activity of T helper (TH) cells (red striped). APC, antigen presenting cell; interleukin (IL)-10, transforming growth factor (TGF)-β, regulatory T cell (Treg) (adapted from Bluestone and Abbas, 2003).

At the end of the caption one finds "adapted from Bluestone and Abbas, 2003".
