However, accumulating evidence suggests that under pathological conditions, BAAT expression and its potential functions in the lungs have increasingly attracted scientific attention.Chen et al. [37] reported activation of the bile acid signaling pathway in the lung tissue of individuals with pulmonary fibrosis, primarily mediated through the FXR receptor, suggesting the possibility of localized bile acid metabolic disturbances. Here, BAAT is linked to pulmonary fibrosis.
