Introduction:
Aspergillus fumigatus is a ubiquitous saprophytic fungus capable of producing small airborne spores, which are frequently inhaled by humans. In healthy individuals, the fungus is rapidly cleared by innate mechanisms, including immune cells. However, in individuals with impaired lung function or immunosuppression the spores can germinate and prompt severe allergic responses, and disease with limited or extensive invasiveness.
Areas Covered:
The traits that make A. fumigatus a successful colonizer and pathogen of humans are multi-factorial. Thus, a global investigative approach is required to elucidate the mechanisms utilized by the fungus to cause disease. Expert commentary: In doing so, a better understanding of disease pathology can be achieved with improved therapeutic/diagnostic solutions, thereby improving patient outcome. Proteomic analysis permits such investigations and recent work has yielded insight into these mechanisms.
Insights
Aspergillus fumigatus spores cause severe allergic responses in immunocompromised individuals. Proteomic analysis is key to understanding fungal disease mechanisms and improving patient outcomes.
Area of Science:
- Medical Mycology
- Immunology
- Proteomics
Background:
- Aspergillus fumigatus is a common airborne fungus.
- Inhaled spores are usually cleared by the immune system in healthy individuals.
- In immunocompromised individuals, spores can germinate, causing severe allergic responses and invasive disease.
Purpose of the Study:
- To investigate the multi-factorial traits of Aspergillus fumigatus enabling colonization and pathogenesis in humans.
- To elucidate the mechanisms by which Aspergillus fumigatus causes disease.
- To improve understanding of disease pathology for better therapeutic and diagnostic solutions.
