Researchers print bacterial biofilms on human lung cells to study chronic lung infections

Some bacterial pathogens form so-called biofilms during infection processes to protect themselves from drugs or cells of the human immune system. Every year, more than 500,000 people die from infections associated with biofilms. Researchers at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) have now developed a novel method to place such biofilms on lung cells in the laboratory. The model system produced by means of "bioprinting" should help to better understand infection processes and assist in the development of new active substances. The researchers have published their results in the journal Biofabrication.
