Polyclonal Treg cells modulate T effector cell trafficking.

ABSTRACT: In this study, we have analyzed the in vivo dynamics of the interaction between polyclonal Foxp3(+) Treg cells, effector T (Teff) cells, and DCs in order to further our understanding of the mechanisms of Treg cell-mediated suppression. Cotransfer of polyclonal activated Treg cells into healthy mice attenuated the induction of EAE. Suppression of disease strongly correlated with a reduced number of Teff cells in the spinal cord, but not with Treg cell-mediated inhibition of Th1/Th17 differentiation. Cotransfer of Treg cells with TCR-Tg Teff cells followed by immunization by multiple routes resulted in an enhanced number of Teff cells in the lymph nodes draining the site of immunization without an inhibition of Teff-cell differentiation. Fewer Teff cells could be detected in the blood in th
