| 1 | Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets. | Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，10： | 5 |
| 2 | Methane production and small intestinal bacterial overgrowth in children living in a slum显示文摘AIM:To analyze small intestinal bacterial overgrowth in school-aged children and the relationship between hydrogen and methane production in breath tests.METHODS:This transversal study included 85 children residing in a slum and 43 children from a private school,all aged between 6 and 10 years,in Osasco,Brazil.For characterization of the groups,data regarding the socioeconomic status and basic housing sanitary conditions were collected.Anthropometric data was obtained in children from both groups.All children completed the hydrogen(H 2) and methane(CH 4) breath test in order to assess small intestinal bacterial overgrowth(SIBO).SIBO was diagnosed when there was an increase in H 2 ≥ 20 ppm or CH 4 ≥ 10 ppm with regard to the fasting value until 60 min after lactulose ingestion.RESULTS:Children from the slum group had worse living conditions and lower nutritional indices than children from the private school.SIBO was found in 30.9%(26/84) of the children from the slum group and in 2.4%(1/41) from the private school group(P = 0.0007).Greater hydrogen production in the small intestine was observed in children from the slum group when compared to children from the private school(P = 0.007).A higher concentration of hydrogen in the small intestine(P < 0.001) and in the colon(P < 0.001) was observed among the children from the slum group with SIBO when compared to children from the slum group without SIBO.Methane production was observed in 63.1%(53/84) of the children from the slum group and in 19.5%(8/41) of the children from the private school group(P < 0.0001).Methane production was observed in 38/58(65.5%) of the children without SIBO and in 15/26(57.7%) of the children with SIBO from the slum.Colonic production of hydrogen was lower in methaneproducing children(P = 0.017).CONCLUSION:Children who live in inadequate environmental conditions are at risk of bacterial overgrowth and methane production.Hydrogen is a substrate for methane production in the colon. | Carolina Santos Mello Soraia Tahan Lígia Cristina FL Melli Mirian Silva do Carmo Rodrigues Ricardo Martin Pereira de Mello Isabel Cristina Affonso Scaletsky Mauro Batista de Morais | 2012 | World Journal of Gastroenterology2012，18，41： | 3 |
