Abstract

The tissue distribution of cellular adhesion molecules (ICAM-1, ELAM-1, VCAM-1) was studied in specimens from six normal human kidneys and in six biopsies from kidneys with tubulointerstitial nephritis associated with Sjögren's syndrome. In addition, the expression of cellular adhesion molecules was examined both in four renal biopsies from cases of tubulointerstitial nephritis of diverse pathogenesis and in six lip biopsies from cases of Sjögren's syndrome. ICAM-1 was expressed on vascular endothelial cells in normal kidneys, in all specimens of tubulointerstitial nephritis and in salivary glands. On tubular epithelial cells, ICAM-1 appeared slightly in normal kidneys; otherwise tubular epithelial ICAM-1 was observed in and around the foci of cellular infiltration in all cases of tubulointerstitial nephritis. ELAM-1 and VCAM-1 were observed on the newly generated vessels in massive cellular infiltrates in some cases of tubulointerstitial nephritis associated with Sjögren's syndrome; by contrast, they were not seen in normal kidneys and in cases of tubulointerstitial nephritis of diverse pathogenesis. In the lip biopsies from salivary glands, ICAM-1 was observed on ductal epithelial cells in and around the foci of cellular infi...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
