Discover how a team of researchers has developed a unique human cell co-culture system to study the infection caused by Francisella tularensis, the culprit behind tularemia. We delve into how this innovative model, combining immune cells called macrophages and liver cells known as hepatocytes, allows for detailed investigation of the infection process and the body's defense mechanisms. Join us to learn how this research sheds light on the different behaviors of various strains of this bacterium and their ability to evade our immune system, ultimately providing valuable insights into potential future treatments
