Detection of immunoglobulins from explant cultures of periapical lesions.
The presence of immunoreactive cells in periapical inflammatory lesions suggests that immune responses participate in the disease process. The purpose of this study was to determine the presence and concentration of immunoglobulins in the supernatant fluids of explant cultures of periapical lesions. Ninety periapical lesions that had been contiguous with the apex of a root were removed and main...
متن کاملMacrophages in periapical lesions.
Macrophages are major constituents of periapical granulomas. They have a central protective role in both innate immunity and adoptive, antigen-specific immune response. Macrophage activation may occur in periapical granulomas by cytokines produced by antigen-activated T-lymphocytes; by bacterial endotoxin, as part of the innate immunity; or by both these processes. Recent studies in athymic ani...
متن کاملEndotoxic activity in periapical lesions.
Thirty tissue samples were examined histologically and classified as being inflamed (apical granulomas) or noninflamed (scars or noninflamed cysts). The samples were then homogenized in pyrogen-free water and treated to remove interfering substances. The presence of endotoxin was then determined by means of the limulus assay; 75 percent of the inflamed tissues were positive for endotoxin, while...
متن کاملPresence of Leptin in chronic periapical lesions
Introduction: Studies have shown the regulatory role of Leptin in bone formation, its expression in adipose tissue as well as increased levels in circulation following the adminstration of inflammatory stimuli such as lipopolysaccharides (LPS). However, there is little data evaluating the role of Leptin in inflammatory periapical lesions. The aim of this study was to evaluate the presence and c...
متن کاملImmune components in human dental periapical lesions.
Immunofluorescence techniques were used to investigate perlapical lesions for the presence of components indicative of hypersensitivity reactlons medlated by humoral factors. In periapical granulomas, IgG, IgA, IgM and IgE cells represented 70, 14, 4 and 10 per cent, respectively, of the immunoglobulin-containing cells (ICC) observed. Intact and apparently degranulating mast cells were seen in ...
