Abstract: As messengers in the intercellular microenvironment, exosomes can mediate the transmission of signals between cells. Alveolar epithelial cells can regulate the body’s innate immune response in the form of exosomes. Under specific stimulation conditions, exosomes derived from alveolar epithelial cells target and regulate the gene expression pathway by delivering different effector active substances, and participate in the regulation of macrophage polarization, thereby controlling the pulmonary inflammatory response. This article reviews the latest research progress of alveolar epithelial cell-derived exosomes in regulating acute lung injury(ALI)by targeting macrophage polarization, provide reference for related research.

Key words: sepsis, acute lung injury, alveolar epithelial cells, alveolar macrophages, exosomes
