| Research Abstract |
We previously reported that mice doubly deficient in tetraspanins CD9 and CD81 reveal a phenotype mimicking human COPD, an inflammatory lung disease. In this study, we found that CD9 negatively regulates LPS-induced macrophage activation in vitro and prevents lung inflammation in vivo. Expression of CD9 was decreased in peripheral blood monocytes in patients with COPD. These indicate that CD9 decrease may be a pathogenetic factor to COPD.
