“…The actions of cytokines include several effects on immune cells and modulation of inflammatory responses [10,11]. The cytokines are produced by cells in the periodontal tissue as fibroblasts and osteoblasts, and they participate in normal physiological bone turnover and remodeling [11][12][13][14][15][16][17]. Many characteristics of these cytokines are of interest in orthodontics, since cytokines in the GCF reflect the microenvironment of periodontal tissues, in which orthodontic forces are applied [2,4,15].…”

Several studies also revealed that cytokines are fundamental in cell signaling in bone [14,18,19] and in mediating mechanically induced bone remodeling (e.g. by orthodontic forces) [1,2,20].…”

OBJECTIVE: This paper aimed to analyze studies in the literature addressing the role of cytokines in the gingival crevicular fluid (GCF) in the orthodontic treatment. METHODS: Several databases were surveyed using both MESH terms and free terms. Additional studies were obtained by reference tracking. This review was registered in PROSPERO, and the procedures foreseen by its statement were followed. Data were obtained from the included studies addressing the orthodontic mechanics, GCF sampling/handling methods, and cytokine measurements. Clinical studies written in English were browsed. Papers were selected by one reviewer and checked by a second investigator. RESULTS: A total of 115 articles were identified, among which 25 were selected for detailed analysis. Common drawbacks consisted mainly of inadequacies in the study design (e.g. short duration and small number of study subjects). The most consistent result was a peak of cytokine levels at 1 d. Associations were observed between prostaglandin E2 (PGE2) and interleukin-1β (IL-1β) and pain, velocity of tooth movement, and treatment mechanics. Interleukin-1b and PGE2 showed different patterns of up-regulation, with IL-1β being more responsive to mechanical stress and PGE2 more responsive to synergistic regulation of IL-1β and mechanical force. The results support the use of light continuous forces for orthodontic treatment. CONCLUSION: There was a tendency of maintenance of relatively high IL-1β levels for longer periods with the use of light continuous forces, which might decrease the frequency of activation. These outcomes provide evidence at the cellular level for the utilization of light continuous forces.Key words: Systematic review; Orthodontics, corrective; Gingival Crevicular Fluid (GCF); Interleukin; T Cells.Papel das citocinas presentes no fluido crevicular durante o tratamento ortodôntico: uma revisão sistemática REsUMO OBJETIVO: Este artigo teve como objetivo analisar estudos na literatura abordando o papel das citocinas no Líquido do Sulco Gengival no tratamento ortodôntico.

“…The best examined pathway includes the balance between Th17 cells and Tregs (18). Because PL-MSCs down-regulate IL-17 production by human T cells (Colic et al, unpublished results), it can be postulated that such a mechanism could be responsible for the counterbalanced action of Th17 cells and Tregs in our model.…”

The pathophysiology of periapical lesions (PLs) is under control of pro-inflammatory and anti-inflammatory (mainly immunoregulatory) cytokines. We have recently established mesenchymal stem cells (MSCs) from PLs and showed their suppressive effects on the production of proinflammatory cytokines from PLs inflammatory cells (ICs). In this work we studied the production of interleukin (IL)-10, IL-27 and transforming growth factor (TGF)-β, by PL-ICs in direct or indirect contacts with PL-MSCs. PL-ICs, which were isolated from four different asymptomatic PLs, predominantly composed of lymphocytes, followed by neutrophil granulocytes, macrophages and plasma cells. PLMSCs, expressing typical MSC markers, were co-cultivated with PL-ICs at 1:10 ratio, either in direct contact or in a transwell-system, for 24 hours. The levels of cytokines in cell-culture supernatants were tested by ELISA. The results showed that PL-MSCs up-regulated the production of all three immunoregulatory cytokines by PL-ICs. PL-MSCs stimulated the production of IL-10 and IL-27 via soluble factors, whereas the up-regulation of TGF-β required direct cell-to-cell contacts. In conclusion, our results showed for the first time the involvement of PL-MSCs in restriction of inflammation in PLs by up-regulation of immunoregulatory cytokines.

“…The presence of specific antibod ies for oral bacteria in patients with periodontitis indicates an involvement of adaptive immune responses [68], of which different T-cell subsets play a detrimental role in the pathogenesis of this inflammatory disease. The T-cell-associated cytokine profile in gingival tissue suggests an engagement of T-helper (Th) 1, Th2, and Th17 cells [69][70][71]. These T-cell subsets are associated with host-derived tissue destruction and bone loss, through, for example, Receptor activator of nuclear factor kappa-B ligand (RANKL) expression.…”

The pathogenicity of the periodontal biofilm is highly dependent on a few key species, of which Porphyromonas gingivalis is considered to be one of the most important pathogens.P. gingivalis expresses a broad range of virulence factors, of these cysteine proteases (gin gipains) are of special importance both for the bacterial survival/proliferation and for the pathological outcome. Several cell types, for example, epithelial cells, endothelial cells, dendritic cells, osteoblasts, and fibroblasts, reside in the periodontium and are part of the innate host response, as well as platelets, neutrophils, lymphocytes, and monocytes/mac rophages. These cells recognize and respond to P. gingivalis and its components through pattern recognition receptors (PRRs), for example, Toll-like receptors and protease-acti vated receptors. Ligation of PRRs induces downstream-signaling pathways modifying the activity of transcription factors that regulates the expression of genes linked to inflamma tion. This is followed by the release of inflammatory mediators, for example, cytokines and reactive oxygen species. Periodontal disease is today considered to play a significant role in various systemic conditions such as cardiovascular disease (CVD). The mechanisms by which P. gingivalis and its virulence factors interact with host immune cells and contribute to the pathogenesis of periodontitis and CVD are far from completely understood.
