Effect of lenalidomide on S100A9 and tumor necrosis factor-α production in peripheral blood mononuclear cells from patients with non-del(5q) myelodysplastic syndrome. (A) Frozen peripheral blood mononuclear cells (PBMC) from lower-risk MDS patients (n=7) were treated with 1 μM lenalidomide for 24 h, before analysis of supernatant S100A9 concentration by ELISA. Results are expressed relative to untreated cells. (B) PBMC from lower-risk MDS patients (n=7) were treated with 1 μM lenalidomide 30 min prior to addition of lipopolysaccharide (LPS) (1 μg/mL): 24 h after stimulation, TNFα ELISA was performed on the supernatants. Results are expressed as a percentage relative to LPS treatment alone. *mean P≤0.05.
