Table 1. Lactoferrin effect on surface marker expression post LPS treatment of CD16⁺ macrophages.

CD16⁺ monocyte derived macrophages were cultured with and without recombinant human lactoferrin (10 μg/mL) in the presence of LPS (5 ng/mL) for 72 h. Cells were collected and analyzed by flow cytometry for surface marker expression. Data reported as mean ± standard deviation.
