Neutrophil extracellular traps impair fungal clearance in a mouse model of invasive pulmonary aspergillosis

2019

Abstract Neutrophil extracellular traps (NETs) are formed by polymorphonuclear neutrophils (PMN) and contribute to the innate host defense by binding and killing bacterial and fungal pathogens. Because NET formation depends on histone hypercitrullination by peptidylarginine deiminase 4 (PAD4), we used PAD4 gene deficient (Pad4-/-) mice in a mouse model of invasive pulmonary aspergillosis (IPA) to address the contribution of NETs to the innate host defense in vivo. After the induction (24 h) of IPA by i.t. infection with Aspergillus fumigatus conidia, Pad4-/- mice revealed lower fungal burden in the lungs, accompanied by less acute lung injury, TNFα and citH3 compared to wildtype controls. T…

IL-27 enhances the lymphocyte mediated innate resistance to primary hookworm infection in the lungs

2020

AbstractInterleukin-27 (IL-27) is a heterodimeric cytokine of the IL-12 family, formed by non-covalent association of the promiscuous EBI3 subunit and selective p28 subunit. IL-27 is produced by mononuclear phagocytes and unfolds pleiotropic immune-modulatory functions through high affinity ligation to IL-27 receptor alpha (IL-27RA). While IL-27 is known to contribute to immunity and to end inflammation following numerous types of infections, its relevance for host defense against multicellular parasites is still poorly defined. Here, we investigated the role of IL-27 during infection with the soil-transmitted hookworm, Nippostrongylus brasiliensis, in its early intrapulmonary life cycle. I…
