Resumo: | This study aims to identify the gene expression of a new group of T lymphocytes, Th9 cells, characteristically responsible for producing IL-9 in the periradicular tissues of individuals with endodontic infections submitted to routine endodontic therapy, in the presence and absence of infection as well as the cytokines TNF-, IL-1. IL-9, INF- and IL-10 and CCL-2 / MCP-1 and CCR-6 chemokines in the periapical interstitial fluid of human root canal infections. Samples were collected immediately after cleaning and formatting procedures and 7 days later (after reduction of intracanal microbial load) to characterize the expression of these genes. Real-time polymerase chain reaction demonstrated significantly higher levels of IL-1, IL-9, INF-, TNF- and IL-10 markers at day 7 compared to day 0. In turn, the CCL-2 / MCP-1 and CCR-6 chemokines and IL- 17A cytokine showed no significant differences in mRNA expression between the 2 periods analyzed. In analyzing the clinical variation after endodontic therapy on periapical immune status, this study demonstrated that the cytokine and chemokinemediated proinflammatory response appears to be modulated in a IL-10 / IL-9 dependent manner. |

IL-9, INF- e IL-10 e das quimiocinas CCL-2/MCP-1 e CCR-6 no fluido intersticial periapical de infeccoes de canais radiculares humanas. As amostras foram coletadas imediatamente apos os procedimentos de limpeza e formatacao e 7dias mais tarde (apos reducao da carga microbiana intracanal) para caracterizar a expressao destes genes. A reacao em cadeia da polimerase em tempo real demonstrou niveis significativamente maiores de marcadores de IL-1, IL-9, INF-, TNF- e IL-10 no dia 7 quando comparado com ao dia 0. Por sua vez, as quimiocinas CCL-2/MCP-1 e CCR-6 e a citocina IL-17A nao apresentaram diferencas significativas na expressao de mRNA entre os 2 periodos analisados. Ao analisar a variacao clinica pos terapia endodontica sobre a condicao imune periapical, este estudo demonstrou que a resposta pro-inflamatoria mediada por citocinas e quimiocinas parece ser modulada de forma IL-10/IL-9 dependente.Universidade Federal de Minas GeraisUFMGAntonio Paulino Ribeiro SobrinhoEvandro Neves AbdoGil Moreira JúniorLucas Moreira Maia2019-08-14T14:13:10Z2019-08-14T14:13:10Z2017-07-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/1843/ODON-AZWKZFinfo:eu-repo/semantics/openAccessporreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMG2019-11-14T17:43:33Zoai:repositorio.ufmg.br:1843/ODON-AZWKZFRepositório InstitucionalPUBhttps://repositorio.ufmg.br/oairepositorio@ufmg.bropendoar:2019-11-14T17:43:33Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
