Affinity-labeling experiments have detected hetero-oligomers of the types I, II, and III transforming growth factor beta (TGF-beta) receptors which mediate intracellular signaling by TGF-beta, but the oligomeric state of the individual receptor types remains unknown. Here we use two types of experiments to show that a major portion of the receptor types II and III forms homo-oligomers both in t...

Transforming growth factor-β1 (TGF-β1) is established to be involved in the pathogenesis of diabetic nephropathy. The diabetic milieu enhances oxidative stress and induces the expression of TGF-β1. TGF-β1 promotes cell hypertrophy and extracellular matrix accumulation in the mesangium, which decreases glomerular filtration rate and leads to chronic renal failure. Recently, TGF-β1 has been demon...

Signals mediated by the transforming growth factor-beta superfamily of growth factors have been implicated in thymic epithelial cell (TEC) differentiation, homeostasis, and function, but a direct reliance on these signals has not been established. Here we demonstrate that a block in canonical transforming growth factor-beta signaling by the loss of Smad4 expression in TECs leads to qualitative ...

The role of transforming growth factor-beta (TGF-beta) in long-term synaptic facilitation was examined in isolated Aplysia ganglia. Treatment with TGF-beta1 induced long-term facilitation (24 and 48 hours), but not short-term (5 to 15 minutes) or intermediate-term (2 to 4 hours) facilitation. The long-term effects of TGF-beta1 were not additive with those of serotonin. Moreover, serotonin-induc...

The establishment of left-right asymmetries in the vertebrate embryo is carried out by complex genetic interactions that impart left- or right-sided information to the developing organs and structures. The origin of LR information is still unclear, but recent advances have provided new insights as to how it is relayed to the embryo node, and thereafter to the lateral plate mesoderm. In both ste...

BACKGROUND AND PURPOSE The aim of this study was to examine the effect of transforming growth factor-beta 1, a cytokine shown to amelioriate cardiac ischemia, in a rabbit model of thromboembolic stroke. METHODS An autologous clot embolus was introduced intracranially through the right internal carotid artery in 21 New Zealand White rabbits, with seven in each group receiving either vehicle co...
