Resumo: | The immunopathological mechanisms involved in the development of leprosy neural injury are not yet fully understood. Thus, the objective of this study was to perform an integrative review in order to identify the involvement of neurotrophin NGF and cytokine TNFα in the pathogenesis of neural injury in leprosy reactions. This review was carried out by search for scientific articles in the databases PubMed, SciELO and Google Acadêmico following the Descriptors of Health Science (DeCS) “Leprosy Reaction”, “Nerve Growth Factor (NGF)”, “Tumor Necrosis Factor- alpha (TNFα)”, and 28 articles was selected. The results showed that in the type 1 reaction there is tissue expression of IL-2, IFNg, TNFα, IL-12 and IL-1b. Whereas the type 2 or ENH reaction has been associated with high TNFα concentrations, neutrophilic infiltration and activation of complement system. High levels of NGF were observed in the lepromatous form of the disease and, low levels, in the tuberculoid form, since this stimulates the expression of TNFα, contributing to the evolution of neural lesions. There seems to be an interaction between NGF and TNFα, since NGF induces endogenous expression of TNFα and this positive feedback promotes a survival of healthy neural cells. |

Por tanto, el objetivo de este trabajo fue realizar una revisión integradora con el fin de identificar la implicación de la neurotrofina NGF y la citoquina TNFα en la patogenia de la lesión neural por lepra. Esta revisión se llevó a cabo mediante la búsqueda de artículos en las plataformas de indexación PubMed, SciELO y Google Scholar con los descriptores de ciencias de la salud (DeCS) “Lepra Reaction”, “Nerve Growth Factor (NGF)”, “Tumor Necrosis Factor-alpha (TNFα)”, obteniendo 28 artículos seleccionados. Los resultados mostraron que durante la reacción de tipo 1 hay expresión tisular de IL-2, IFNg, TNFα, IL-12 e IL-1b. La reacción tipo 2 o ENL, por otro lado, se ha asociado con altas concentraciones de TNFα, infiltración neutrofílica y activación del sistema del complemento. Se observaron niveles elevados de NGF en la forma lepromatosa y niveles bajos en la forma tuberculoide de la enfermedad, ya que este estimula la expresión de TNFα, lo que contribuye a la evolución de las lesiones neurales. Parece haber una interacción entre NGF y TNFα, ya que NGF induce la expresión endógena de TNFα y esta retroalimentación positiva promueve la supervivencia de las células neurales sanas.Os mecanismos imunopatológicos envolvidos no desenvolvimento de lesão neural hansênica ainda não são completamente esclarecidos. Sendo assim, o objetivo deste trabalho foi realizar uma revisão integrativa a fim de identificar o envolvimento da neurotrofina NGF e da citocina TNFα na patogênese da lesão neural hansênica. Esta revisão foi realizada mediante a busca de artigos nas plataformas indexadoras PubMed, SciELO e Google Acadêmico com os Descritores em Ciências da Saúde (DeCS) “Leprosy Reaction”, “Nerve Growth Factor (NGF)”, “Tumor Necrosis Factor- alpha (TNFα)”, sendo selecionados 28 artigos. Os resultados evidenciaram que durante a reação do tipo 1 há expressão tecidual de IL-2, IFN-g, TNFα, IL-12 e IL-1b. Já a reação do tipo 2 ou ENH tem sido associada com altas concentrações de TNFα, infiltração neutrofílica e ativação do sistema complemento. Altos níveis de NGF foram observados na forma lepromatosa e baixos níveis na forma tuberculoide da doença, pois nesta há estímulo da expressão de TNFα o que contribui para a evolução de lesões neurais. Parece haver uma interação entre NGF e TNFα, uma vez que o NGF induz a expressão endógena de TNFα e esse feedback positivo promove uma sobrevida das células neurais saudáveis.Research, Society and Development2021-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1582310.33448/rsd-v10i6.15823Research, Society and Development; Vol. 10 No. 6; e29010615823Research, Society and Development; Vol. 10 Núm. 6; e29010615823Research, Society and Development; v. 10 n. 6; e290106158232525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15823/14103Copyright (c) 2021 Suzana Alves Mundim Carneiro; Isabella Tavares Souza ; Raika Eduarda Rodrigues da Silva ; Emerith Mayra Hungria Pinto; Aline de Araújo Freitashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCarneiro, Suzana Alves Mundim Souza , Isabella Tavares Silva , Raika Eduarda Rodrigues daPinto, Emerith Mayra Hungria Freitas, Aline de Araújo 2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15823Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:33.972353Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
