Thirteen genes share our set of differentially expressed genes in PBMCs after acute intake of phenol-rich olive oil and MEGN: JUN, RGS1, CXCL2, ANXA3, RASGEF1B, CD83, CA2, EGR2, DIAPH3, CCL3, and TLR7, PSAP and IFIT3. De Mello et al. assessed individuals with both impaired glucose metabolism and MetS on how long-term weight loss affects expression of cytokines in PBMCs. Here, CXCL2 is linked to metabolic syndrome.
