Cím:Protective and destructive immune reactions in apical periodontitis / I. J. Márton, C. Kiss
Dátum:2000
ISSN:0902-0055
Megjegyzések:Apical periodontitis is initiated primarily by the mixed microflora of infected root canals. Continuous flow of bacteria and their products through the apical foramen induces influx, activation and coordinated interaction of immune-inflammatory cells within the periapical area. Successful mobilization of host defense mechanisms prevents abundant extraradicular bacterial invasion. However, anti-infective effector mechanisms are not restricted to killing the invading microorganisms but also destroy normal tissue components and induce bone absorption, resulting ultimately in the loss of the affected teeth. Moreover, autocrine and paracrine loops of stimulation may lead to the perpetuation of the local inflammatory lesion and may also alter the function of remote tissues and organs. This review attempts to summarize current knowledge about the pathogenic mechanism of apical periodontitis, focusing on the formation of a special granulation tissue that effectively fights bacteria originated from the infected pulp chamber and, by exerting this protective function, also contributes to harmful local and distant events. The dynamic equilibrium between defensive and destructive mechanisms may provide a pathobiological basis for better understanding of clinical signs and symptoms of various forms of apical periodontitis lesions and influence treatment strategy and practice.

Cím:Differential in situ distribution of interleukin-8, monocyte chemoattractant protein-1 and Rantes in human chronic periapical granuloma / I. J. Márton, A. Rot, E. Schwarzinger, S. Szakáll, T. Radics, I. Vályi-Nagy, C. Kiss
Dátum:2000
ISSN:0902-0055
Megjegyzések:In situ distribution of three prototype chemokines interleukin (IL)-8, monocyte chemoattractant protein (MCP)-1 and Rantes was determined in chronic human periapical granulomas by immunohistochemistry using monoclonal antibodies. IL-8 was found primarily in the cytoplasm of the Malassez epithelial cells. MCP-1 immunoreactivity was confined to the endothelial cells that lined small venules. Each of the three investigated chemokines, including Rantes, exhibited a characteristic binding pattern to the extracellular matrix of the lesion. The observed chemokines may play a role in establishing the cellular composition of chronic apical periodontitis, thus augmenting the intensity of local inflammation and tissue damage.

Cím:Interleukin-6 and granulocytemacrophage colony-stimulating factor in apical periodontitis : correlation with clinical and histologic findings of the involved teeth / T. Radics, C. Kiss, I. Tar, I. J. Márton
Dátum:2003
ISSN:0902-0055
Megjegyzések:Apical periodontitis is characterized by the presence of immunocompetent cells producing a wide variety of inflammatory mediators. Releasing cytokines with long-range action, such as interleukin-6 (IL-6) and granulocyte-macrophage colony-stimulating factor (GM-CSF), apical periodontitis may induce changes in remote organs of the host. This study quantified the levels of IL-6 and GM-CSF in symptomatic and asymptomatic human periradicular lesions. Lesions were also characterized by size and histologic findings. Tissue samples were homogenized and supernatants were assayed using an enzyme-linked immunosorbent assay (ELISA). Correlations between cytokine levels and characteristic features (as single variables) of the lesions were analysed. There was a trend for higher levels of IL-6 and GM-CSF in symptomatic than in asymptomatic lesions, but the difference was not significant. Levels also tended to be higher in large than in small lesions, in polymorphonuclear (PMN) cell-rich than in PMN cell-poor samples, and in epithelialized than in non-epithelialized lesions. Significantly higher levels of IL-6 (778.1 +/- 220.5 pg/microg) and GM-CSF (363.3 +/- 98.4 pg/microg) were found in samples coincidentally possessing symptomatic and epithelialized features than in asymptomatic, small, PMN cell-poor, non-epithelialized lesions (IL-6: 45.2 +/- 13.1 pg/microg and GM-CSF: 135.1 +/- 26.4 pg/microg). These results suggest that symptomatic lesions containing epithelial cells represent an immunologically active stage of apical periodontitis, whereas asymptomatic, small, PMN cell-poor, non-epithelialized lesions represent healing apical lesions.

Cím:Progressive increase of human papillomavirus carriage rates in potentially malignant and malignant oral disorders with increasing malignant potential / Szarka Krisztina, Tar Ildikó, Fehér Enikő, Gáll Tamás, Kis Andrea, D. Tóth Etelka, Boda Róbert, Márton Ildikó, Gergely Lajos
Dátum:2009
Megjegyzések:We investigated the potential role of human papillomaviruses (HPVs) in potentially malignant oral disorders, oral leukoplakia (OL) and oral lichen planus (OLP), and in oral squamous cell cancer (OSCC) in an Eastern Hungarian population with a high incidence of OSCC. Methods: Excised tumor samples (65 OSCC patients) and exfoliated cells from potentially malignant lesions (from 44 and 119 patients with OL and OLP, respectively) as well as from healthy controls (72 individuals) were analysed. OLPs were classified based on clinical appearance, 61 patients had erosive?atrophic lesions (associated with higher malignancy risk, EA-OLP) and 58 had non-erosive non-atrophic lesions (with lower risk of becoming malignant, non-EA-OLP), respectively. Exfoliated cells collected from apparently healthy mucosa accompanied each lesion sample. HPV was detected by MY/GP polymerase chain reaction (PCR) and genotyped by restriction analysis of amplimers. Copy numbers in lesions were determined using real-time PCR. Prevalence rates, copy number distributions, and association with risk factors and diseases were analysed using chi-square test, t-test, and logistic regression, respectively. Results: We detected HPVs significantly more frequently in lesions than in controls (P ? 0.001 in all comparisons). HPV prevalence increased gradually with increasing severity of lesions (32.8, 40.9, and 47.7% in OLP, OL, and OSCC, respectively). Copy number distribution patterns roughly corresponded to prevalence rates, but OLP and OL were comparable. HPV prevalence differed significantly between EA-OLP and non-EA-OLP groups (42.6 vs. 22.4%); EA-OLP group showed a prevalence similar to that found in OL. Conclusion: HPVs may be involved in the development or progression of not only OSCC but also of potentially malignant oral lesions.
