Lung Innate Immunity and Inflammation

While reductionist in vitro approaches have allowed for careful interrogation of cellular pathways that underlie innate immune responses, they often fail to capture the complex multicellular interactions characteristic of acute inflammation. Intravital microscopy, by directly observing alveolar cell-cell interactions, provides unique insight into the complex intercellular mechanisms responsible for alveolar inflammation. This review discusses multiple potential approaches to intravital pulmonary imaging, with specific attention to in vivo microscopy of the freely moving mouse lung.
