The Effects of Titanium Surfaces Modified with an Antimicrobial Peptide GL13K by Silanization on Polarization, Anti-Inflammatory, and Proinflammatory Properties of Macrophages

Figure 3

ELISA analysis of the secretion of IL-1β and TNF-α in macrophages with M1 polarization and IL-10 and IL-1ra in macrophages with M2 polarization cultured on the titanium surface, the silanized titanium surface, and the GL13K-coated surface at 24 h. Error bars represent for . The downregulation of the secretion level of cytokines TNF-α () and the upregulation of cytokines IL-10 () were detected in the GL13K immobilized titanium group.
