Fungal infections: Immune defense, immunotherapies and vaccines

Area of Science:

• Mycology
• Immunology
• Infectious Diseases

Background:

• Invasive fungal infections (IFIs) represent a significant and escalating global health challenge.
• The World Health Organization (WHO) has identified key fungi posing health threats, emphasizing the need for improved interventions and antifungal resistance strategies.
• Current antifungal drugs have limited efficacy and face challenges due to rapidly evolving drug resistance in fungal species.

Purpose of the Study:

• To review the mechanisms by which host innate immune cells recognize and respond to fungal pathogens.
• To explore the role of immunomodulation as a therapeutic strategy for disseminated fungal diseases.
• To discuss emerging antifungal immunotherapies and vaccines as potential future treatments.

Main Methods:

• Review of scientific literature on host-innate immune cell recognition of fungi via pattern recognition receptors.
• Analysis of effector mechanisms and adaptive immune responses involved in fungal clearance.
• Examination of preclinical and clinical data on immunotherapies and vaccines for fungal infections.

Main Results:

• Host innate immune cells utilize pattern recognition receptors to detect invading fungi.
• Immune responses involve effector mechanisms and adaptive immunity crucial for fungal clearance.
• Emerging immunotherapies and vaccines show promise in expanding antifungal treatment options.

Conclusions:

• The host immune system plays a critical role in controlling fungal infections (mycoses).
• Immunomodulation presents a promising therapeutic avenue for disseminated fungal diseases.
• Antifungal immunotherapies and vaccines are emerging as vital additions to the antifungal armamentarium.
