Genetic variation in PFKFB3 impairs antifungal immunometabolic responses and pr...
Gonçalves, Samuel M.; Antunes, Daniela; Leite, Luis; Mercier, Toine; Horst, Rob Ter; Vieira, Joana; Espada, Eduardo; Pinho Vaz, Carlos; Branca, RosaActivation of immune cells in response to fungal infection involves the reprogramming of their cellular metabolism to support antimicrobial effector functions. Although metabolic pathways such as glycolysis are known to represent critical regulatory nodes in antifungal immunity, it remains undetermined whether these are differentially regulated at the interindividual level. In this study, we identify a key role...
PTX3 Polymorphisms Influence Cytomegalovirus Reactivation After Stem-Cell Trans...
Campos, Cláudia F.; Leite, Luís; Pereira, Paulo; Vaz, Carlos Pinho; Branca, Rosa; Campilho, Fernando; Freitas, Fátima; Ligeiro, Dário; Marques, AntónioBackground: Reactivation of latent human cytomegalovirus (CMV) in patients undergoing allogeneic stem-cell transplantation (HSCT) predisposes to several clinical complications and is therefore a major cause of morbidity and mortality. Although pentraxin-3 (PTX3) has been previously described to bind both human and murine CMV and mediate several host antiviral mechanisms, whether genetic variation in the PTX3 lo...

IL-10 overexpression predisposes to invasive aspergillosis by suppressing antif...
Cunha, Cristina; Gonçalves, Samuel M.; Duarte-Oliveira, Claudio; Leite, Luis; Lagrou, Katrien; Marques, António; Lupianez, Carmen B.; Mesquita, Inês[Excerpt] To the Editor: Proinflammatory immune responses are critically required for antimicrobial host defenses; however, excessive inflammation has the potential to damage host tissues thereby paradoxically contributing to the progression of infection.[...]

Cunha, Cristina; Gonçalves, Samuel M.; Duarte-Oliveira, Cláudio; Leite, Luís; Lagrou, Katrien; Marques, António; Lupiañez, Carmen B.; Mesquita, InêsProinflammatory immune responses are critically required for antimicrobial host defenses; however, excessive inflammation has the potential to damage host tissues thereby paradoxically contributing to the progression of infection. A central negative regulator of inflammatory responses is IL-10, an immunosuppressive cytokine with a wide variety of functions across multiple cell types. Although the role of IL-10 ...
Twenty Years of Autologous Stem Cell Transplantation in Diffuse Large B-Cell Ly...
Brito, Margarida Dantas; Campilho, Fernando; Branca, Rosa; Vaz, Carlos; Roncon, Susana; Campos, AntónioIntroduction: Diffuse large B-cell lymphoma can be cured in 60% – 70% of patients. Autologous stem cell transplantation is the standard treatment for relapsed disease. This high-intensity treatment after first complete remission in patients with high International Prognostic Index remains controversial and was performed in our department during some years. Material and Methods: Retrospective study, review of cl...
Outcomes of allogeneic stem cell transplantation among patients with acute myel...
Bezerra de-Mello, Ramon Andrade; Pinho-Vaz, Carlos; Branca, Rosa; Campilho, Fernando; Rosales, Maria; Roncon, Susana; Campos-Junior, AntonioIntroduction: Allogeneic hematopoietic stem cell transplantation (ASCT) represents a potentially curative approach for patients with relapsed or refractory acute myeloid leukemia (AML). We report the outcome of relapsed/refractory AML patients treated with ASCT.Method: A retrospective cohort from 1994 to 2013 that included 61 patients with diagnosis of relapsed/refractory AML. Outcomes of interest were transpla...
Fanconi anemia: cytogenetic diagnosis of 40 cases.
Porto, Beatriz; Sousa, Rosa; Ponte, Filipa; Torgal, Ana; Campilho, Fernando; Campos, António; Gonçalves, Cristina; Barbot, JoséFanconi Anemia (FA) is a rare recessive disorder clinically characterized by progressive bone marrow failure, diverse congenital malformations and increased predisposition to cancer. Given the late onset of anemia, relatively to other cytopenias, and the high variability in the phenotype, a correct clinical diagnosis is difficult, and may be delayed or even missed. This fact may be prejudicial to patients, due ...
