Figure 1From: PPAR Gamma agonists regulate tobacco smoke-induced toll like receptor 4 expression in alveolar macrophagesPhagocytosis by alveolar macrophages from each group. Macrophages were harvested from the BAL fluid of different groups and were cultured in media for 3 and 24 hrs. The results are presented as mean ± SD (n = 6). *P < 0.05 and **P < 0.01 compared with the sham group; #P < 0.05 and ##P < 0.01 compared with the CS only-exposed group.Back to article page
