From: Expression of Semaphorin 4A and its potential role in rheumatoid arthritis
Correlation between serum semaphorin 4A (Sema4A) and cytokine levels in patients with rheumatoid arthritis. ELISA was performed to quantify the serum levels of Sema4A, IL-6, and TNF-α in RA patients. Correlation between serum Sema4A and the level of IL-6 (a), and TNF-α (b) assessed by Pearson correlation analysis. c A putative model illustrating the interactions of Sema4A/NF-κB in modulating cell phenotype through control of IL-6 production
