Human T lymphocyte subpopulations in chronic periapical lesions.
Bacteria and altered host tissue substances are potential antigens capable of initiating immunological reactions in periapical tissues via the root canal system (1, 2). These reactions include humoral immune responses mediated by B lymphocytes and plasma cells, and cellmediated immune responses through the actions of T lymphocytes and lymphokines. Different classes of immunoglobulins have been ...
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 کاملClinical, morphological and immunohistochemical aspects in laryngeal premalignant lesions.
OBJECTIVE We investigated the proliferative activities in premalignant laryngeal vocal chord lesions treated by epithelial stripping in microlaryngoscopy, using immunohistochemical staining with anti-p53, anti-PCNA and anti-Ki-67 monoclonal antibody and we correlated with clinic and morphologic aspects. MATERIAL AND METHODS The study was made on 32 patients hospitalized in Craiova ENT Clinic ...
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...
