Cytokine expression by MΦIFN-γ from HLA-B27+ SpA compared with HLA-B27– SpA, RA and healthy donors
Graphs represent mRNA expression of IL-23p19, IL-12p35, IL-12p40, IL-10 and TNF by MΦIFN-γ after lipopolysaccharide stimulation. The mRNA levels were measured by qRT-PCR, normalized to the expression of GAPDH. Bars represent the mean (s.e.m.). *P < 0.05, **P < 0.01.
