Embark on a fascinating journey into the intricate world of the liver and its defenders, the natural killer cells. This podcast delves into groundbreaking research that brings us closer to understanding how our liver's immune system, with NK cells at the forefront, tackles threats like pathogens and injury. Join us as we explore the innovative development of a microfluidically perfused liver-on-a-chip model, a sophisticated in vitro system that now includes functional human NK cells. Discover how this cutting-edge technology allows scientists to study the complex interactions of NK cells with other liver cells and their role in liver inflammation, offering exciting new possibilities for future immunological studies and a deeper appreciation for our body's natural defenses.
