The diversity in virulence of different Aspergillus fumigatus strains was studied in an experimental murine model of invasive pulmonary aspergillosis (IPA) and the results were correlated with possession of a putative molecular marker of virulence. Seven strains from different patients with non-invasive or invasive aspergillosis and four environmental(More)
There is now considerable evidence that cerebral malaria may be related to the over-production of tumour necrosis factor (TNF). Nevertheless, our knowledge is very poor concerning the biological events which lead up to this TNF over-production. Furthermore, interleukin-6 (IL-6) is produced in large amounts during malaria infection and seems to have(More)
Tumour necrosis factor (TNF) plays a pivotal role in the induction of cerebral complications during Plasmodium falciparum malaria. TNF secretion by macrophages can be induced by lipopolysaccharide (LPS) and by P. falciparum antigens, but it is unclear whether similar mechanisms control the monokine expression in both cases. The signal transduction pathway(More)
Cerebral malaria is probably related to an overstimulation of the immune system and the cytokine network. We have previously demonstrated that tumour necrosis factor (TNF) secretion by human macrophages can be induced by soluble and heat-stable malarial antigens. Indirect evidence from epidemiological and in vitro studies suggests that Pf155/RESA can be(More)
