Each of the effector CD4 T-cell lineages - Th1, Th2, and the more recently identified Th17 - arises from pluripotent naïve precursors whose developmental fate is largely controlled by cytokines that act in concert with antigenic signals. Remarkably, development of the Th17 lineage has been linked to that of regulatory T cells, which obviate or downregulate Th17 responses to preserve immune home...

oral lichen planus (olp) is a chronic inflammatory disease of the oral mucosa which is considered by the world health organization (who) as a premalignant condition. one step in malignant development is so called epithelial mesenchymal transition (emt), a process whereby epithelial cells acquire mesenchymal characteristics. a factor known to induce emt is the transforming growth factor-β (tgf-β...

background: successful pregnancy in allopregnant women depends upon the control of graft rejection mechanisms. it has been suggested that some immunosuppressive cytokines contribute to successful pregnancy and transplantation. transforming growth factor beta (tgf-   β) exhibits potent immunoregulatory and anti-inflammatory properties which might prolong graft survival. recent studies suggest a ...

The same enzyme is responsible for the activation of transforming growth factor-beta-like signalling molecules and the processing of fibrillar procollagens. This finding implicates a metalloendoprotease in the control of cell behavior and matrix assembly during morphogenesis.

Fibrosis is a scarring process that is a common feature of chronic organ injury. It is characterized by elevated activity of transforming growth factor-beta resulting in increased and altered deposition of extracellular matrix and other fibrosis-associated proteins. Recent work has demonstrated that bone morphogenetic protein-7 blocks transforming growth factor-beta signaling. Moreover, member ...
