Evaluation of Bronchoalveolar Lavage Fluid Cytokines as Biomarkers for Invasive...
Gonçalves, Samuel Martins; Lagrou, Katrien; Rodrigues, Claudia S.; Campos, Claudia F.; Bernal-Martinez, Leticia; Rodrigues, Fernando José dos SantosBackground: Invasive pulmonary aspergillosis (IPA) is an infection that primarily affects immunocompromised hosts, including hematological patients and stem-cell transplant recipients. The diagnosis of IPA remains challenging, making desirable the availability of new specific biomarkers. High-throughput methods now allow us to interrogate the immune system for multiple markers of inflammation with enhanced reso...
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.[...]
The microbiome-metabolome crosstalk in the pathogenesis of respiratory fungal d...
Gonçalves, Samuel Martins; Lagrou, Katrien; Oliveira, Cláudio Manuel Duarte; Maertens, Johan A.; Cunha, Cristina Amorim; Carvalho, AgostinhoFilamentous fungi of the genus Aspergillus are responsible for several superficial and invasive infections and allergic syndromes. The risk of infection and its clinical outcome vary significantly even among patients with similar predisposing clinical factors and pathogen exposure. There is increasing evidence that the individual microbiome supervises the outcome of the host-fungus interaction by influencing me...

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 ...
Genetic PTX3 deficiency and aspergillosis in stem-cell transplantation
Rodrigues, Fernando José dos Santos; Cunha, Cristina; Aversa, Franco; Lacerda, João F.; Busca, Alessandro; Kunzai, Oliver; Grube, MatthiasBACKGROUND: The soluble pattern-recognition receptor known as long pentraxin 3 (PTX3) has a nonredundant role in antifungal immunity. The contribution of single-nucleotide polymorphisms (SNPs) in PTX3 to the development of invasive aspergillosis is unknown. METHODS: We screened an initial cohort of 268 patients undergoing hematopoietic stem-cell transplantation (HSCT) and their donors for PTX3 SNPs modifying th...
