Candida innate immunity at the mucosa.

Area of Science:

• Immunology
• Microbiology
• Mycology

Background:

• The human body hosts diverse microbial communities on mucosal surfaces.
• Distinguishing commensal microbes from pathogenic ones is crucial for mucosal health.
• Candida albicans, a fungal pathobiont, is asymptomatically carried by ~60% of humans.

Purpose of the Study:

• To review the innate immune responses to Candida albicans at mucosal surfaces.
• To understand how the immune system manages C. albicans, a common commensal that can become pathogenic.

Main Methods:

• This is a review article, summarizing existing research.
• It focuses on the detection of C. albicans, particularly its hyphal form.
• It examines the resulting innate immune signaling pathways and effector functions.

Main Results:

• Innate immune detection of C. albicans hyphae triggers significant responses.
• These responses include the production of antimicrobial peptides, danger-associated molecular patterns, and cytokines.
• These mechanisms aim to control fungal burdens and prevent infection.

Conclusions:

• The innate immune system plays a critical role in managing Candida albicans at mucosal sites.
• Understanding these responses is key to addressing C. albicans-associated morbidities and invasive infections.
• Further research into mucosal immunity is vital for maintaining host-microbe homeostasis.
