Therefore, we chose the inflammation array Cat# QAH-INF-G3-4 to quantify 40 proteins in our plasma samples, including TNF RI, TNF RII, BLC, MIP-1b, eotaxin, eotaxin-2, MIG, MCSF, G-CSF, GM-CSF, MCP-1, MIP-1a, MIP-1d, PDGF-BB, TIMP-1, TIMP-2, I-309, TNFa, TNFb, RANTES, IFNg, ICAM-1, IL-1a, IL-1b, IL-1RA, IL-2, IL-4, IL-5, IL-6, IL-6R, IL-7, IL-8, IL-10, IL-11, IL-12p40, IL-12p70, IL-13, IL-15, IL-16, and IL-17, and samples from both SLE patients and healthy controls were quantified. Here, IL4 is linked to systemic lupus erythematosus.
