Activated T regulatory cells (Tregs) express latent TGF-?1 on their cell surface
bound to GARP. Although integrins have been implicated in mediating the release
of active TGF-?1 from the complex of latent TGF-?1 and latent TGF-?1 binding
protein, their role in processing latent TGF-?1 from the latent TGF-?1/GARP
complex is unclear. Mouse CD4(+)Foxp3(+) Treg, but not CD4(+)Foxp3(-) T cells,
expressed integrin ?8 (Itgb8) as detected by quantitative RT-PCR. Itgb8
expression was a marker of thymically derived (t)Treg, because it could not be
detected on Foxp3(+)Helios(-) Tregs or on Foxp3(+) T cells induced in vitro.
Tregs from Itgb8 conditional knockouts exhibited normal suppressor function in
vitro and in vivo in a model of colitis but failed to provide TGF-?1 to drive
Th17 or induced Treg differentiation in vitro. In addition, Itgb8 knockout Tregs
expressed higher levels of latent TGF-?1 on their cell surface consistent with
defective processing. Thus, integrin ?v?8 is a marker of tTregs and functions in
a cell intrinsic manner in mediating the processing of latent TGF-?1 from the
latent TGF-?1/GARP complex on the surface of tTregs.
