Definition / general
- Binds to CD55 and G protein-coupled receptors
- May be involved in cell adhesion and signaling processes early after leukocyte activation
- May be involved in migration of neutrophils (J Immunol 2004;172:1125)
- Highly expressed at sites of inflammation in skin, lung and rheumatoid arthritis
- May contribute to angiogenesis associated with tumors (Blood 2005;105:2836)
- Glycosylation causes CD97 to show two different epitopes, EGF and Stalk (Int J Cancer 2004;112:815)
Uses by pathologists
- No significant clinical use by pathologists
Microscopic (histologic) images
Positive staining - normal
- Activated T > B cells, monocytes / macrophages, dendritic cells, granulocytes, smooth muscle cells
Positive staining - disease
- GI carcinomas (Oncol Rep 2005;14:1413, Am J Clin Pathol 2002;118:699), thyroid carcinoma (stronger if undifferentiated, J Clin Endocrinol Metab 1999;84:1104)
