Figure Lengend Snippet: Characterization of PBMCs from CRMO patients. (A-E) Real Time-PCR analysis of gene products involved in the regulation of IL-1β, including ASC , NLRP3 , CASP-1 , IL-1β and of the pro-inflammatory cytokine TNF-α in freshly isolated PBMCs obtained from CRMO patients in remission (gray dots) or with active disease (black dots) and healthy controls (white dots). Values are presented as arbitrary unit (AU). (F-G) IL-1β released in supernatants by PBMCs isolated from CRMO patients in remission or in active disease and from healthy controls, after stimulation with 10 ng/ml LPS for 3 hours (F) or 10 ng/ml LPS for 2 hours followed by treatment with 2 mM ATP for 1 hour (G) . IL-1β was measured by ELISA. Black lines represent the mean value. *p < 0.05, **p < 0.01 vs healthy controls.
Article Snippet: Real-time PCR assays were performed using TaqMan Universal PCR Master mix (Applied Biosystems) and the following gene-expression assays: human IL-1β, TNF-α, CASP-1, ASC and NLRP3 (Applied Biosystem).
Techniques: Real-time Polymerase Chain Reaction, Isolation, Enzyme-linked Immunosorbent Assay
