To understand the modulation and the behavior of glycocalyx elements during adhesion, we explored one of its components, the CD43 molecule, on human monocytic THP-1 cells exposed to cytokine stimulation and its redistribution during heterotypic adhesion to opsonized erythrocytes. First we demonstrated by immunofluorescence and immunoprecipitation that CD43 is dys-sialylated in monocytic THP-1 cells stimulated by interferon-gamma (IFN-gamma) and tumor necrosis factor alpha (TNF-alpha) and stimulation increased correlated to heterotypic adhesion. CD43 anti-adhesive effect seemed to be related to sialic acid moeties because an increase in adhesion was also induced by sialidase treatment and by monoclonal antibodies recognizing sialic acid-dependent epitopes on CD43. Second, a redistribution of CD43 molecules was observed after adhesion, resulting in the exclusion of CD43 molecules from contact areas as demonstrated by immunofluorescence and by ultrastructural immunogold localization. We therefore demonstrated in monocytic THP-1 cells that some glycocalyx molecules can be modulated by cytokines and redistributed during adhesion. These results support the concept that CD43 can regulate cell interactions.
