Abstract
The transforming growth factor (TGF) superfamily encompasses about 30 members in mammals. The effect of TGF-β subfamily members is exerted and regulated via selective pathways of synthesis and signaling that involve activation of latent TGF-β, specific and high-affinity binding to cell membrane serine/threonine kinase receptors, activation of intracellular cascades that include Smad molecules and mitogen-activated protein kinases, and regulated termination of the effect by diverse mechanisms including protein degradation and transcriptional activation. Several comprehensive reviews on TGF-β biology in general and on the role of this cytokine in other diseases have been published recently. In recent years an unexpected role of TGF-β on lung homeostasis has been revealed. Here, we discuss the contribution of TGF-β to the pathogenesis of asthma and chronic obstructive pulmonary disease, two common illnesses of the lung, as well as of lymphangioleiomyomatosis, a rare disease in women. The information we collate and integrate places TGF-β at a pivotal point within complex networks that control lung physiology as well as the physiopathology of these lung diseases.
