Abstract.

We molecular-cloned a novel 80-kDa human glycosyl-phosphatidyl inositol (GPI)-anchored protein, designated GPI-80, that may regulate neutrophil extravasation. To identify the possible role of GPI-80 in vivo, we examined the immunohistochemical localization of GPI-80 in various human tissues. Our data show that GPI-80 is mainly located in polymorphonuclear leukocytes (PMNs), endothelial cells of the vessels, parietal cells and mucous neck cells of the stomach, goblet cells of the jejunum, and alveolar macrophages of the lung. The pathomechanisms of these positive findings in the gastric glands and the intestinal glands are not well elucidated and further studies will be needed.
