Quantification for IL-10 (A), TGF-β (B), IL-1β (C), TNF-α (D), MCP-1 (E), and IL-6 (F) protein concentration in primary human macrophages with a single LPS stimulation and incubated with the anti-CD163 antibody (RM3/1) or its isotype control (Iso) for 24 hours (72 hours after the addition of LPS). N = 6–10 per group. #p<0.05, vs. isotype control by student’s t-test.
