Dendritic Cell Regulation of Graft-Vs.-Host Disease: Immunostimulation and Tolerance.

abstract：:Protein kinase C isoform θ (PKCθ) is a key modulator of TCR signaling and mediates activation of NF-κB, NF-AT, and AP-1 transcription factors. Although in vitro studies of PKCθ(-/-) T cells have shown impaired activation responses, in vivo studies indicate that PKCθ requirement is not universal. While PKCθ is importan...
