Organization of immune responses requires exchange of information between cells. This is achieved through either direct cell-cell contacts and establishment of temporary synapses or the release of soluble factors, such as cytokines and chemokines. Here we show a novel form of cell-to-cell communication based on adenosine triphosphate (ATP). ATP released by(More)
T cell-intrinsic transforming growth factor β (TGFβ) receptor signaling plays an essential role in controlling immune responses. The RING-type E3 ligase Cbl-b has been shown to mediate the sensitivity of T cells to TGFβ; however, the mechanism underlying this process is unknown. This study shows that SMAD7, an established negative regulator of TGFβ receptor(More)
Previous studies have suggested that T-lymphocyte dysfunction might be attributable to nitrative stress induced by reactive nitrogen species (RNS). In this manuscript, we explored this hypothesis and provided a direct demonstration of the inhibitory effects of RNS on human T-cell signaling, activation, and migration. We found that short exposure of human T(More)
As you can see below there is an interest in the paper, but the referees also bring up important concerns with the paper, both conceptual and technical. In particular, issues are raised regarding the role of ATP on T cell motility. It is unclear if the raised issues can be addressed and if you can provide more data to support the conclusions, which is what(More)
