Induction of the Lung Myofibroblast PDGF Receptor System by Urban Ambient Particles from Mexico City

Platelet-derived growth factor (PDGF) and its receptor system regulate mesenchymal cell proliferation. We recently reported that emission-source fly-ash particles and asbestos fibers induce the PDGF alpha-receptor through a macrophage-dependent pathway, and upregulation of this receptor greatly enha...
