Intercellular communication is critical for integrating complex signals in multicellular eukaryotes. Vascular endothelial cells and T lymphocytes closely interact during the recirculation and trans-endothelial migration of T cells. In addition to direct cell-cell contact, we show that T cell deriv...

Transcription profiling by microarray was performed to pinpoint the roles of transforming growth factor B1 (TGFB1) in embryonic differentiation of the small intestine. An organ culture system in which mouse jejunal rudiments were placed on semipermeable platforms and fed with chemically defined seru...

Signaling through the thrombospondin-1 receptor CD47 broadly limits cell and tissue survival of stress, but the molecular mechanisms are incompletely understood. We now show that loss of CD47 permits sustained proliferation of primary murine endothelial cells and enables these cells to spontaneously...

CD4+Foxp3+ regulatory T cells (Treg) are essential for immune homeostasis and maintenance of self-tolerance. They are produced in the thymus and also generated de novo in the periphery in a TGFB dependent manner. Foxp3+ Treg are also required to achieve tolerance to transplanted tissues when induced...
