Eosinophils in fungal diseases: An overview

Area of Science:

• Immunology
• Pulmonology
• Mycology

Background:

• Eosinophils are central to allergic asthma and allergic bronchopulmonary mycosis (ABPMs).
• The precise roles of eosinophils in the immunopathology of these conditions are not fully elucidated.
• Mechanisms of direct molecular interactions between fungi and eosinophils remain largely unknown.

Purpose of the Study:

• To provide an overview of eosinophil contributions to allergic asthma and ABPMs.
• To revise mechanisms of fungal recognition by eosinophils.
• To examine advances in understanding eosinophil innate effector responses to fungi and their therapeutic relevance.

Main Methods:

• Literature review and synthesis of existing research.
• Analysis of immunological mechanisms of eosinophil-fungal interactions.
• Examination of therapeutic implications for fungal-associated allergic lung diseases.

Main Results:

• Eosinophils are significant effector cells in fungal-associated allergic airway diseases.
• General mechanisms of fungal recognition by eosinophils are outlined.
• Specific molecular interactions between eosinophils and fungi like Alternaria alternata, Candida albicans, and Aspergillus fumigatus are discussed.

Conclusions:

• Understanding eosinophil-fungal interactions is crucial for elucidating the immunopathology of ABPMs and related asthma.
• Further research into these molecular mechanisms may reveal novel therapeutic targets.
• Targeting eosinophil responses holds promise for treating fungus-associated allergic pulmonary diseases.
