Breakthrough at Uniklinikum Jena: New molecules stop deadly lung infections

Jena, 05.05.2026. Researchers from Uniklinikum Jena and the Universität Magdeburg have succeeded in a promising step towards treating severe lung infections. A new medicinal approach specifically blocks the tissue-destroying toxins of the pathogens.

  • Researchers involved: Molecular medicine specialists from Uniklinikum Jena and chemists from the Universität Magdeburg.
  • The discovery: Synthetically modified sterols neutralize the destructive toxins of bacteria and fungi.
  • Medical goal: Mitigation of invasive lung infections, improvement of intensive care outcomes, and relief for the healthcare system.

Paradigm shift in infection therapy

Until now, life-threatening lung infections caused by bacteria or fungi have primarily been combated with classic antibiotics and antifungals. The interdisciplinary research team from Jena and Magdeburg has now demonstrated an alternative path in experiments: instead of attacking the microorganisms directly, their most dangerous tool is specifically disabled.

Pathogens in the lungs secrete toxins that destroy tissue cells. It is only through this targeted destruction of lung tissue that the microorganisms are able to spread extensively and cause life-threatening conditions in the patient.

Synthetic sterols as a protective shield

The scientists’ solution is based on the use of synthetically modified sterols. These are cholesterol-like, natural components of the cell membrane. Recent experiments show that these modified molecules are capable of intercepting and deactivating the pathogens’ toxins before they can damage the lung tissue.

In addition to this active protective function, the sterols offer another decisive advantage: they stabilize the membranes of the body’s own cells. This makes the lung cells overall more resistant to the hostile attacks of the pathogens.

Background: Significance for intensive care medicine

The Universitätsklinikum Jena (UKJ), centrally located in the Jena district of Lobeda, is the most important pillar of maximum medical care and research in Thüringen. Invasive lung infections represent an enormous problem in intensive care units worldwide – also due to increasing resistance to conventional antibiotics. A therapeutic approach that merely deprives the pathogens of their destructive toxins instead of killing them could save lives in the future and significantly shorten lengthy intensive care treatments.
