Resumo: | Antiretroviral therapies have increased the life expectancy of people living with HIV, however a major concern is the increase in comorbidities, such as cardiovascular, metabolic bone and neurodegenerative diseases, which are the result of an immunosensitivity phenomenon associated with the cellular aging of the system immunological, called immunossenescence. This article aims to analyze the main factors promoting this event in HIV infection, discussing whether it is the result of chronic viral persistence or antiretroviral therapy. This is a review of the literature developed from consultation with the Virtual Health Library, using the MEDLINE and LILACS databases. The results showed that the HIV virus has the potential to influence the senescence of immune cells by reducing the number of CD4+ T lymphocytes, increasing CD8+ T lymphocytes, with shorter telomeres, and with a low rate of renewal due to deficiency in the production of its precursors. In addition, treatment with antiretrovirals also has the ability to accelerate the senescence of immune cells, either by the action of NRTIs on the enzyme telomerase or on the polymerase of mitochondria or by producing oxidative stress. Therefore, the evidence suggests that both processes can contribute to the accelerated establishment of a low-grade chronic inflammatory phenotype resulting in significant early immune remodeling in HIV infection. |

Este artículo tiene como objetivo analizar los principales factores que promueven este evento en la infección por VIH, discutiendo si es consecuencia de la persistencia viral crónica o de la terapia antirretroviral. Esta es una revisión de la literatura desarrollada a partir de la consulta con la Biblioteca Virtual en Salud, utilizando las bases de datos MEDLINE y LILACS. Los resultados mostraron que el virus VIH tiene el potencial de influir en la senescencia de las células inmunes al reducir el número de linfocitos T CD4 +, aumentar los linfocitos T CD8 +, con telómeros más cortos y con una baja tasa de renovación debido a la deficiencia en la producción de sus precursores. Además, el tratamiento con antirretrovirales también tiene la capacidad de acelerar la senescencia de las células inmunes, ya sea por la acción de los INTI sobre la enzima telomerasa o sobre la polimerasa de las mitocondrias o produciendo estrés oxidativo. Por lo tanto, la evidencia sigiere que ambos processos pueden contribuir al establecimiento acelerado de um fenótipo inflamatório crónico de bajo grado que resulta em uma remodelación inmune temprana significativa em la infección por VIH.As terapias antirretrovirais proporcionaram aumento da expectativa de vida das pessoas vivendo com HIV, entretanto uma grande preocupação é o aumento de comorbidades, como doenças cardiovasculares, metabólicas, ósseas e neurodegenerativas, as quais são resultantes de um fenômeno de imunossensibilidade associado ao envelhecimento celular do sistema imunológico, denominado imunossenescência. Este artigo tem como objetivo analisar os principais fatores promotores desse evento na infecção por HIV, discutindo se é resultado de persistência viral crônica ou de terapia antirretroviral. Trata-se de uma revisão da literatura desenvolvida a partir de consulta a Biblioteca Virtual em Saúde, utilizando os bancos de dados MEDLINE e LILACS. Os resultados mostraram que o vírus HIV tem o potencial de influenciar na senescência das células do sistema imunológico pela redução no número de linfócitos T CD4+, aumento de células T CD8+, encurtamento dos telômeros e baixa taxa de renovação pela deficiência na produção de seus precursores. Além disso, o tratamento com antirretrovirais também tem capacidade de acelerar a senescência das células do sistema imune, seja pela ação dos NRTIs sobre a enzima telomerase ou sobre a polimerase das mitocôndrias ou ainda produzindo estresse oxidativo. Portanto, as evidências sugerem que ambos os processos podem contribuir para o estabelecimento acelerado de um fenótipo inflamatório crônico de baixo grau resultando em uma remodelação imune precoce significativa na infecção por HIV.Research, Society and Development2020-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/743610.33448/rsd-v9i9.7436Research, Society and Development; Vol. 9 No. 9; e592997436Research, Society and Development; Vol. 9 Núm. 9; e592997436Research, Society and Development; v. 9 n. 9; e5929974362525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7436/6784Copyright (c) 2020 João Victor Cruz Meireles; Maysa de Vasconcelos Britohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMeireles, João Victor Cruz Brito, Maysa de Vasconcelos2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7436Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:09.656524Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
