Beyond tissue concentrations: antifungal penetration at the site of infection

Area of Science:

• Pharmacology
• Mycology
• Infectious Diseases

Background:

• Invasive fungal infections cause significant global morbidity and mortality.
• Current antifungal therapies are often limited by insufficient drug exposure at infection sites.
• Limited understanding exists regarding antifungal drug distribution and penetration within diverse tissue subcompartments.

Purpose of the Study:

• To review current knowledge on antifungal drug exposure at infection sites.
• To introduce matrix-assisted laser desorption ionization (MALDI) mass spectrometry imaging as a novel technique.
• To highlight the potential of MALDI-MS imaging to enhance understanding of antifungal drug penetration.

Main Methods:

• Review of existing literature on antifungal drug exposure.
• Description of matrix-assisted laser desorption ionization (MALDI) mass spectrometry imaging technique.
• Discussion of the application of MALDI-MS imaging in studying drug distribution.

Main Results:

• Current understanding of antifungal drug distribution in tissues is incomplete.
• MALDI-MS imaging offers unprecedented spatial resolution for drug distribution analysis.
• This technique can visualize drug concentrations in various tissue microenvironments.

Conclusions:

• Improved understanding of antifungal drug distribution is critical for optimizing current therapies.
• MALDI-MS imaging presents a powerful new tool for investigating drug penetration and exposure.
• Further research using MALDI-MS imaging can guide the development of novel antifungal agents with enhanced efficacy.
