Assembly 3 is a dynamic and friendly Assembly. In 2017, the Assembly changed its name from “Cell and Molecular Biology” to its current name (Basic and Translational Sciences) to better reflect its activities and focus. We provide a platform for interaction between basic scientists and practising clinicians who are interested in the cellular and molecular mechanisms involved in healthy and diseased lungs. A key focus of our Assembly is tracking scientific developments that easily translate into better diagnostic technologies or enhanced patient care. As such we are centrally involved in devising the content of the Scientific Year in Review and Scientific Grand Round at the ERS International Congress.
