title: [Scavenger receptor gene--regulation of scavenger receptor gene expression in alveolar macrophages and the pathogenesis of pulmonary alveolar proteinosis].
abstract: It was previously reported, that scavenger receptors expressed on the surface membrane of human alveolar macrophages, mediated endocytosis of a diverse group of negatively charged macromolecules. Moreover, it was reported that scavenger receptors might contribute to host-defense function and it was also reported that the expression of scavenger receptors was suppressed by some cytokines, interferon-gamma, tumor necrosis factor-alpha, and transforming growth factor-beta 1. In our previous study, we suggested that one of the pathogenesises of pulmonary alveolar proteinosis may be involved in the suppressed expression of scavenger receptors by TGF-beta 1. In this paper, the regulation of scavenger receptor gene expressions is summarized and further we refer to the pathogenesis of pulmonary alveolar proteinosis.
