Abstract

Dendritic cells (DC) initiate primary immune reactions and are distributed throughout most tissues. The most potent DC population of the kidney has long been suggested to reside within the glomerular mesangium. Using LEW.1A rats, we enriched and characterized such low-density cells. Mesangial DC generally exhibited round to oval cell bodies and cytoplasmic veils. Phenotypically, these cells were 100% OX-6++, 45% OX-42++, 35% ED1low, 10% OX-62low, and negative for ED2 and alpha-naphtylbutyrate esterase. Introducing a new monoclonal antibody, R3, which stains a subset of splenic DC, we showed strong antigen expression on 60% of mesangial DC. Correlating cell populations were detected immunohistochemically. Functionally, mesangial DC potently stimulated allogeneic mixed leucocyte reactions, but did not phagocytose opsonized Escherichia coli. In addition to their striking phenotypic similarity with autologous splenic DC, mesangial DC exhibited 88% of the allostimulatory activity of splenic DC. Calculation indicated approximately two mesangial DC per glomerulum. We suggest that these cells comprise different maturation-dependent subsets. The OX-62 integrin especially appears to be expressed only on mature mesangial DC, which may cor...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.
