The blood–brain barrier internalises Cryptococcus neoformans via the EphA2‐tyrosine kinase receptor
Cryptococcus neoformans is an opportunistic fungal pathogen that causes life‐threatening meningitis most commonly in populations with impaired immunity. Here, we resolved the transcriptome of the human brain endothelium challenged with C.

Phenotypic switching in Cryptococcus neoformans [PDF]
Phenotypic switching has been described in serotype A and D strains ofCryptococcus neoformans. It occursin vivoduring chronic infection and is associated with differential gene expression and changes in virulence. The switch involves changes in the polysaccharide capsule and cell wall that affect the yeast's ability to resist phagocytosis. In addition,

This study involved a total of 116 samples, 79 taken from pigeon droppings and 37 of atmospheric air taken close to accumulations of excrement. Cryptococcus neoformans var. grubii was isolated from 11 (13.9%) of these samples.

Mechanisms of Pulmonary Escape and Dissemination by Cryptococcus neoformans
Cryptococcus neoformans is a common environmental saprophyte and human fungal pathogen that primarily causes disease in immunocompromised individuals. Similar to many environmentally acquired human fungal pathogens, C.

Cryptococcus neoformans: "An Ascomycete"
ConclusionsThese observations would seem to indicate that Cryptococcus neofor-mans and Lipomyces starkeyi may be one and the same organism, and that it is frequently isolated from the soil.

Localization of mannoprotein in Cryptococcus neoformans [PDF]
Cell wall mannoprotein of nonpathogenic yeasts is surface exposed, since the cells are agglutinated by concanavalin A and antimannoprotein antibodies. However, nonencapsulated cells of Cryptococcus neoformans were agglutinated neither by concanavalin A nor by antimannoprotein antibodies.

Peeling the onion: the outer layers of Cryptococcus neoformans
Cryptococcus neoformans is an opportunistic fungal pathogen that is ubiquitous in the environment. It causes a deadly meningitis that is responsible for over 180,000 deaths worldwide each year, including 15% of all AIDS-related deaths. The high mortality

Promising Prodiginins Biological Activities
ABSTRACT Prodiginins are a large family of at least 34 pyrrolic compounds, including the well‐studied red pigment prodigiosin. Prodiginins are produced by several microorganisms displaying broad biological activities, including antimicrobial, antiviral, antiparasitic, antiproliferative, and immunosuppressive activities.

Fungi undergo changes in cell shape in response to environmental stimuli that drive pathogenesis and niche adaptation, such as the yeast-to-hyphal transition of dimorphic fungi in response to changing temperature.

ABSTRACT The chemical composition of 66 oil samples isolated from the berries of individual trees of Juniperus phoenicea var. turbinata, collected in six locations from Algeria, was investigated by gas chromatography with flame ionization detection, gas chromatography‐mass spectrometry, and 13C‐nuclear magnetic resonance.
