Because increased levels of AnxA1 (12) are found in bronchoalveolar lavage (BAL) fluids of a range of pathologic conditions, such as lung cancer, chronic obstructive pulmonary disease, and bronchial asthma (12, 16, –18), we addressed whether FPR activation via AnxA1 impacts the generation or activation of AMs. Here, ANXA1 is linked to lung carcinoma.
