title: Connective tissue in diabetes mellitus: biochemical alterations of the intercellular matrix with special reference to proteoglycans, collagens and basement membranes.
abstract: Diabetes mellitus induces alterations in the metabolism of the macromolecules present in the intercellular matrices and particularly in the basement membranes. These contribute to the morphological changes characteristic of the disease : basement membrane thickening, skin thickening and induration. Accumulation of overglycosylated collagens and diminution of sulfated proteoglycan concentrations are the most generally reported biochemical modifications in human or animal diabetic states. More limited data are available concerning elastin, fibronectin and laminin in diabetes.
