Allograft rejection mediated by memory T cells is resistant to regulation.

TL;DR: Data indicate that the relative resistance of both CD4+ and CD8+ alloreactive memory T cells to regulation may mediate resistance to tolerance induction seen in hosts with preexisting alloantigen-specific immunity and further indicate the multiplicity of mechanisms by which Tregs may control alloimmune responses in vivo.
Journal ArticleDOI

Hypoxia inducible factor 1α regulates T cell receptor signal transduction

TL;DR: It is found that constitutive activity of Hif-1α resulted in diminished Ca2+ response upon TCR crosslinking despite equivalent activation of phospholipase Cγ1, normal intracellularCa2+ stores, and normal entry of Ca 2+ across the plasma membrane.
Journal ArticleDOI

Mechanisms Underlying Blockade of Allograft Acceptance by TLR Ligands

TL;DR: The data suggest that TLR signals do not prevent prolonged graft acceptance by directing natural Tregs into the Th17 lineage or by using other IL-6-dependent mechanisms, and that graft destruction results from the ability of CpG to drive Th1 differentiation and interfere with immunoregulation established by alloreactive natural CD4+Foxp3+ T Regs.
