DNA damage in circulating leukocytes measured with the comet assay may predict ...
Bonassi, Stefano; Ceppi, Marcello; Møller, Peter; Azqueta, Amaya; Milić, Mirta; Monica, Neri; Brunborg, Gunnar; Godschalk, Roger; Koppen, GudrunThe comet assay or single cell gel electrophoresis is the most common method used to measure strand breaks and a variety of other DNA lesions in human populations. To estimate the risk of overall mortality, mortality by cause, and cancer incidence associated with DNA damage, a cohort of 2,403 healthy individuals (25,978 person-years) screened in 16 laboratories using the comet assay between 1996 and 2016 was fo...

Milić, Mirta; Ceppi, Marcello; Bruzzone, Marco; Azqueta, Amaya; Brunborg, Gunnar; Godschalk, Roger; Koppen, Gudrun; Langie, Sabine; Møller, PeterThe alkaline comet assay, or single cell gel electrophoresis, is one of the most popular methods for assessing DNA damage in the human population. One of the open issues concerning this assay is the identification of those factors that can explain the large inter-individual and inter-laboratory variation. International collaborative initiatives such as the hCOMET project - a COST Action launched in 2016 - repre...

Definition of the anti-inflammatory oligosaccharides derived from the galactosa...
Gressler, Markus; Heddergott, Christoph; N'Go, Inés C.; Renga, Giorgia; Oikonomou, Vasilis; Moretti, Silvia; Coddeville, Bernadette; Gaifem, JoanaGalactosaminogalactan (GAG) is an insoluble aminosugar polymer produced by Aspergillus fumigatus and has anti-inflammatory properties. Here, the minimum glycosidic sequences required for the induction of IL-1Ra by peripheral blood mononuclear cells (PBMCs) was investigated. Using chemical degradation of native GAG to isolate soluble oligomers, we have found that the de-N-acetylation of galactosamine residues an...
CD4+ T cell vaccination overcomes defective cross-presentation of fungal antige...
Luca, Antonella De; Iannitti, Rossana G.; Bozza, Silvia; Beau, Remi; Casagrande, Andrea; D’Angelo, Carmen; Moretti, Silvia; Cunha, CristinaAspergillus fumigatus is a model fungal pathogen and a common cause of infection in individuals with the primary immunodeficiency chronic granulomatous disease (CGD). Although primarily considered a deficiency of innate immunity, CGD is also linked to dysfunctional T cell reactivity. Both CD4+ and CD8+ T cells mediate vaccine-induced protection from experimental aspergillosis, but the molecular mechanisms leadi...
Immunity and tolerance to fungi in hematopoietic transplantation : principles a...
Carvalho, Agostinho; Cunha, Cristina; Bozza, Silvia; Moretti, Silvia; Massi-Benedetti, Cristina; Bistoni, Francesco; Aversa, Franco; Romani, LuiginaResistance and tolerance are two complementary host defense mechanisms that increase fitness in response to low-virulence fungi. Resistance is meant to reduce pathogen burden during infection through innate and adaptive immune mechanisms, whereas tolerance mitigates the substantial cost of resistance to host fitness through a multitude of anti-inflammatory mechanisms, including immunological tolerance. In exper...

Carvalho, Agostinho; De Luca, Antonella; Bozza, Silvia; Cunha, Cristina; D’Angelo, Carmen; Moretti, Silvia; Perruccio, Katia; Iannitti, Rossana G.Aspergillus fumigatus is a model fungal pathogen and a common cause of severe infections and diseases. CD8+ T cells are present in the human and murine T-cell repertoire to the fungus. However, CD8+ T-cell function in infection and the molecular mechanisms that control their priming and differentiation into effector and memory cells in vivo remain elusive. In the present study, we report that both CD4+ and CD8+...
