Lipophilic dye staining of Cryptococcus neoformans extracellular vesicles and capsule.
Cryptococcus neoformans is an encapsulated yeast that causes systemic mycosis in immunosuppressed individuals. Recent studies have determined that this fungus produces vesicles that are released to the extracellular environment both in vivo and in vitro. These vesicles contain assorted cargo that includes several molecules associated with virulence and implicated in host-pathogen interactions, ...
متن کاملSerum albumin disrupts Cryptococcus neoformans and Bacillus anthracis extracellular vesicles.
For both pathogenic fungi and bacteria, extracellular vesicles have been shown to contain many microbial components associated with virulence, suggesting a role in pathogenesis. However, there are many unresolved issues regarding vesicle synthesis and stability, including the fact that vesicular packaging for extracellular factors involved in virulence must also have a mechanism for vesicle unl...
متن کاملExtracellular vesicles from Cryptococcus neoformans modulate macrophage functions.
Cryptococcus neoformans and distantly related fungal species release extracellular vesicles that traverse the cell wall and contain a varied assortment of components, some of which have been associated with virulence. Previous studies have suggested that these extracellular vesicles are produced in vitro and during animal infection, but the role of vesicular secretion during the interaction of ...
متن کاملExtracellular DNase activity of Cryptococcus neoformans and Cryptococcus gattii.
Extracellular DNase activity was studied in 73 strains of Cryptococcus neoformans and 12 strains of Cryptococcus gattii. DNase activity was measured by DNase agar clearance with and without Methyl Green. All strains tested showed extracellular DNase activity and no significant difference was found betweenC. neoformans and C. gattii strains. DNase production was higher in strains from clinical o...
متن کاملeffect of iron on capsule biosynthesis of cryptococcus neoformans
ln this study several tests showed that high level of iron either in sera from patients with rheumatoid arthritis, th alassaemia major or in standard iron solutions, have inhibitory effect oil capsule production of cryptococcus neotormans. this work is concerned with the probable role of iron in pigeon's natural resistance against cryptococcal infection: no protease activity was detected in eit...
