Dangerous pathogens use this sophisticated machinery to infect hostsMay 17, 2019
Gastric cancer, Q fever, Legionnaires’ disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3-D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details. This could in the future enable the development of precisely targeted antibiotics for the aforementioned diseases.
