"These are the first structures our immune system scans when it encounters the fungus—like a fingerprint of the pathogen," explains Prof. Peter H. Seeberger. "We set out to understand exactly what the human immune system detects at the very start." In infected blood, antibodies bind to specific fungal sugars, revealing the glycan structures present on the surface and recognized by the immune system. Extending this to fungal infections would protect the most vulnerable patients and trigger strong, long-lasting immune memory.
