[Demonstration of soluble IgG-Fc type II receptors (or s-Fc-gamma-II-R) in human whole saliva].
Twenty human salivary samples from two groups of patients (with or without dental caries) were tested for the presence of soluble forms of Fc gamma receptors type II (sFc gamma RII): sFc gamma RII were detected by immunoblotting using a radiolabelled monoclonal antibody directed against human Fc gamma RII. These soluble forms specifically interact with the Fc portion of IgG and are produced by cells of the immune system (macrophages, neutrophils, Langerhans cells). This study showed that sFc gamma RII are present in human unstimulated saliva. The statistical analysis indicated that the relative amounts of sFc gamma RII in human unstimulated saliva are variable depending on the patient. No apparent association was found between the sFc gamma RII and the oral status of the patients.
