Lung system

The "lung system" refers to the respiratory organs and tissues involved in breathing and gas exchange in the body. It is not a molecular or therapeutic target, but rather a complex system composed of multiple cell types, extracellular matrices, and anatomical structures. In the context of disease, particularly lung cancer, molecular targets are more specifically individual genes (e.g., EGFR, ALK, KRAS), proteins, or receptors within lung tissues[4][5][2]. The WHO classification of lung cancer, for example, organizes neoplasms by cell and molecular subtype (e.g., non-small cell lung cancer, small cell lung cancer) rather than considering the "lung system" as a molecular target[5]. No specific abbreviation, mechanism of action, or interacting drugs exist for the "lung system" as a molecular target. Where relevant, research and treatment focus on defined molecular entities within lung tissues, such as growth factor receptors or oncogenes.
