Fungal infections represent an increasing health crisis, especially for immune-deficient patients. American scientists now report in the journal Angewandte Chemie that specific help could be provided by small-molecule immunotherapeutics with novel mechanism of action. They developed small bifunctional molecules that simultaneously bind both chitin, a specific feature of the fungal cell wall and a molecule not found in humans, and naturally occurring human antibodies and redirect the human immune system to eliminate fungal pathogens.
