Inhibition of autophagic capacity with ageing was postulated to generate a pro-inflammatory condition via activation of inflammasomes, a group of Interleukin-1 activating intracellular multi-protein complexes. We thus investigated gene expression of inflammasome components in PBMC of 77 vascular patients (age 22–82) in association with age. Findings: Linear regression of real-time qRT-PCR data revealed a significant positive association of gene expression of each of the inflammasome components with age (Pearson correlation coefficients: AIM2: r = 0.245; P = 0.032; NLRP3: r = 0.367; P = 0.001; ASC (PYCARD): r = 0.252; P = 0.027; CASP1: r = 0.296; P = 0.009; CASP5: r = 0.453; P = 0.00003; IL1B: r = 0.247; P = 0.030). No difference in gene expression of AIM2, NLRP3, ASC CASP1, and CASP5 was detected between PBMC of patients with advanced atherosclerosis and other vascular patients, whereas IL1B expression was increased in PBMC of the latter group (P = 0.0005). Conclusion: The findings reinforce the systemic pro-inflammatory phenotype reported in elderly by demonstrating an increased phase-1 activation of inflammasomes in PBMC of vascular patients. date: 2015 publisher: BioMed Central id_scheme: DOI ppn_swb: 1653712732 own_urn: urn:nbn:de:bsz:16-heidok-195832 language: eng bibsort: WUXIAOYUGENEEXPRES2015 full_text_status: public publication: Immunity & Ageing volume: 12 number: 15 place_of_pub: London pagerange: 1-5 issn: 1742-4933 citation: Wu, Xiaoyu ; Hakimi, Maani ; Wortmann, Markus ; Zhang, Jian ; Böckler, Dittmar ; Dihlmann, Susanne (2015) Gene expression of inflammasome components in peripheral blood mononuclear cells (PBMC) of vascular patients increases with age.
