Abstract

The human immune response to extracellular substances (ES) from Actinobacillus actino-mycetemcomitans Y4 were analyzed. Twenty-nine periodontal patients with generalized severe alveolar bone loss and 13 healthy volunteers were examined for serum IgG antibody titers against ES, Among the patients, 17 had higher antibody titers than healthy individuals (high-titer patients) but the remainder (low-titer patients) did not. Two-dimensional electrophoresis (2DE) and Western blots demonstrated that two proteins (40 and 37 kDa) and three smeared substances reacted with IgGs from high-titer patients, but not with IgGs from healthyvolunteers, The low-molecular-mass smear at the acid side reacted with over 90% of all patients. This smear reacted with anti-ii. actinomycetemcomitans lipopolysaccharide (LPS) monoclonal antibody which recognized LPS from each A, actinomycetemcomitans serotype, The high molecular mass smear at the acid side might be serotype-specific O-antigens of LPS, Another high molecular mass smear which located from the alkaline to the neutral side reacted with anti-serotype-b-specific capsular polysaccharide monoclonal antibody, Moreover, the 40- and 37-KDa proteins reacted with this anti-capsular polysaccharide antibody. This results suggested that 40- and 37-kDa proteins which reacted with 100% or 88% of high-titer patients might be glycoproteins linked with capsularpolysaccharide.
