From: Melatonin promoted chemotaxins expression in lung epithelial cell stimulated with TNF-α
Eosinophil chemotactic activity (ECA) released from A549 cells. Melatonin (10-6M) alone did not change the ECA released from A549 cells. TNF-α (100 ng/ml) could increase the ECA released from A549 cells. Melatonin (from10-10 to 10-6M) increased the ECA released from A549 cell in a dose dependent manner when co-stimulated with TNF-α(100 ng/ml). **, p < 0.01, compared with control and melatonin alone (n = 3). #, p < 0.01, compared with TNF-α alone (n = 3).
