Signature cytokine-associated transcriptome analysis of effector γδ T cells ide...
Inácio, Daniel; Amado, Tiago; Pamplona, Ana; Sobral, Daniel; Cunha, Carolina; Santos, Rita F.; Oliveira, Liliana; Rouquié, Nelly; Carmo, Alexandre M.γδ T cells producing either interleukin-17A (γδ cells) or interferon-γ (γδ cells) are generated in the mouse thymus, but the molecular regulators of their peripheral functions are not fully characterized. Here we established an Il17a-GFP:Ifng-YFP double-reporter mouse strain to analyze at unprecedented depth the transcriptomes of pure γδ cell versus γδ cell populations from peripheral lymph nodes. Within a very...
Effects of methanolic and aqueous extracts of Carica papaya leaf on miRNA-media...
Jacques, Filipa; Delgadinho, Mariana; Ginete, Catarina; Gomes, Mário; Ribeiro, Edna; Brito, Miguel; Gomes, Anita Q.Introduction: Hemoglobinopathies are genetic blood disorders characterized by abnormal hemoglobin that disrupts oxygen transport and leads to diverse health complications. Raising fetal hemoglobin (HbF) levels is one possible therapeutic approach. But the current main therapy based on the use of hydroxyurea (HU), faces limitations related to cost and safety, especially in underserved areas. To overcome these co...
Portuguese cork industry: filling the knowledge gap regarding occupational expo...
Viegas, Carla; Dias, Marta; Pacífico, Cátia; Faria, Tiago; Clérigo, Anália Matos; Dias, Hermínia Brites; Caetano, Liliana Aranha; Carolino, ElisabeteIntroduction: The presence of the Penicillium section Aspergilloides (formerly known as Penicillium glabrum) in the cork industry involves the risk of respiratory diseases such as suberosis. Methods: This study aimed to corroborate the predominant fungi presents in this occupational environment by performing a mycological analysis of 360 workers’ nasal exudates collected by nasal swabs. Additionally, evaluation...
Towards an integrated approach on occupational health to tackle COVID-19 pandemic
Ribeiro, Edna; Oliveira, Ketlyn; Dias, Marta; Gomes, Bianca; Pimenta, Raquel; Delgadinho, Mariana; Ginete, Catarina; Abreu, RenatoBackground: Serological screening is crucial for the prevention of infection, ensuring the maintenance of the worker’s health, and thus promoting occupational health. It was reported that SARS-CoV-2 can survive in aerosols and on dry surfaces for several days to weeks. Objectives: We aimed to apply an integrated approach to Occupational Health to tackle the COVID-19 pandemic. Materials and methods: We performed...

Dissecting the role of microRNAs in effector versus regulatory CD4+ T cell diff...
Cunha, Carolina; Romero, Paula Vargas; Inácio, Daniel; Pais, Ana Teresa; Pelicano, Catarina; Sobral, Daniel; Costa, Marina; Mensurado, SofiaIntroduction: MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. They have been implicated in the regulation of the differentiation and function of CD4+ T cell subsets, key players in host defense against pathogens, but also responsible for immune-mediated diseases depending on the correct vs incorrect balance, respectively, between pro-infla...
Dissection of the IFN-γ versus IL-17-specific transcriptomes of γδ T cells: a n...
Inácio, Daniel; Amado, Tiago; Pamplona, Ana; Sobral, Daniel; Cunha, Carolina; Lesourne, Renaud; Gomes, Anita Q.; Silva-Santos, BrunoThe crucial role of murine γδ T cells in several (patho)physiological contexts stems from a complex process of ‘developmental pre-programming’ in the thymus, after which a significant fraction of γδ T cells populate peripheral sites already endowed with the capacity to secrete either IL-17 or IFN-γ. However, despite the relevance of these γδ T cell effector subsets, we still lack knowledge on the transcriptomes...
Effects of Quercetin in transcriptional and post-transcriptional regulation of ...
Canteiro, Beatriz; Mendes, Maria; Jacques, Filipa; Delgadinho, Mariana; Oliveira, Ketlyn; Ginete, Catarina; Gomes, Mário; Ribeiro, Edna; Brito, MiguelHemoglobinopathies are a group of inherited blood disorders that primarily affect red blood cells. The most common type is known as sickle cell anemia (SCA). It is characterized by mutations in the HBB gene, which encodes the β-subunit of human hemoglobin, giving rise to hemoglobin S (HbS). When deoxygenated, HbS polymerizes in the red blood cell, giving it a sickle shape and making it rigid and fragile. Fetal ...

Canteiro, Beatriz; Mendes, Maria; Jacques, Filipa; Delgadinho, Mariana; Oliveira, Ketlyn; Ginete, Catarina; Gomes, Mário; Ribeiro, Edna; Brito, MiguelSickle Cell anemia (SCA) is a hereditary hemoglobinopathy with the formation of hemoglobin S, associated with severe health outcomes. Currently, induction of fetal hemoglobin (HbF) is one of the most promising therapeutic strategies. Here we aimed to assess the potential of the natural compound Quercetin, in transcriptional expression of globin and HbF regulatory/silencing genes. In this study, the K562 cell li...
