Abstract

Human mononuclear phagocytes from healthy individuals were cultured in plasma and sera from normal persons and patients with chronic renal failure receiving haemodialysis. There was a marked detachment of macrophages from the glass coverslips when the cells were grown for 4 days in uraemic serum or plasma compared to normal serum. The ability of the macrophages to adhere to the glass coverslips was reduced when the cells were cultured in plasma from normal persons and uraemics subjected to systemic heparinization. However, the toxic effect of in vivo heparinization was much higher in the uraemics than in normal persons. Heparin added to normal and uraemic blood samples in vitro far in excess of in vivo heparinization did not influence the macrophage function to the same extent. Cell toxic substances seem to be produced as a consequence of systemic heparinization. These substances were not removed during 100 minutes of haemodialysis. Heparin added to pooled A Rh+ serum in concentrations far above those present in plasma following in vivo heparinization had little adverse effect on the macrophage function.

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.
