Abstract

Arthritis typically involves recurrence and progressive worsening at specific predilection sites, but the checkpoints between remission and persistence remain unknown. Here, we defined the molecular and cellular mechanisms of this inflammation-mediated tissue priming. Re-exposure to inflammatory stimuli caused aggravated arthritis in rodent models. Tissue priming developed locally and independently of adaptive immunity. Repeatedly stimulated primed synovial fibroblasts (SFs) exhibited enhanced metabolic activity inducing functional changes with intensified migration, invasiveness and osteoclastogenesis. Meanwhile, human SF from patients with established arthritis displayed a similar primed phenotype. Transcriptomic and epigenomic analyses as well as genetic and pharmacological targeting demonstrated that inflammatory tissue priming relies on intracellular complement C3- and C3a receptor-activation and downstream mammalian target of rapamycin- and hypoxia-inducible factor 1α-mediated metabolic SF invigoration that prevents activation-induced senescence, enhances NLRP3 inflammasome activity, and in consequence sensitizes tissue for inflammation. Our study suggests possibilities for therapeutic intervention abrogating tissue priming without immunosuppression.

Mice on the BALB/c and C57BL/6 backgrounds and Wistar rats were bred in house and kept in temperature- and humidity-controlled facilities at the University of Erlangen, Germany, the Medical University of Vienna, Austria, or the Faculty of Medicine, University of Belgrade, Serbia, respectively, group housed with free access to food and water and 12 h light/dark cycles. Complement C3-deficient C3 tm1Crr mice were bought from Jackson, SCID mice (CB17/Icr-Prkdc scid ) and NOD/ShiLtJ were from Charles River Germany. C3ar −/− mice were from Jörg Köhl, University of Lübeck, Germany. Rag1 −/− mice and Col6a1 cre :R26-tdTomato reporter mice, both on C57BL/6 background, were gifts from Mario Zaiss and Clemens Neufert, respectively, both from the University of Erlangen. The inducible hTNFtg mice homozygous for the Tg_rtTA2S transgene and the human TNFα transgenes have been described previously ( Retser et al., 2013 ). Mice expressing a Cre recombinase under the Cx3cr1 promoter together with a Cre-inducible diphtheria toxin (DT) receptor (Cx3cr1cre;iDTR mice) were generated by breeding C57BL/6-Gt(ROSA)26Sortm1(HBEGF)Awai/J (iDTR) purchased from Jackson with STOCK Tg(Cx3cr1cre)MW126Gsat/Mmucd mice (Cx3cr1cre) (identification number 036395-UCD) from the Mutant Mouse Regional Resource Center (MMRC), a National Institutes of Health (NIH)- funded strain repository. Resident tissue macrophages become specifically depleted in DT-treated Cx3cr1cre:iDTR mice several days after DT injection, since blood monocytes repopulate within 48 h after DT application. Wistar rats were derived from Charles River. The animal studies were approved by the local ethical committees and conducted according to the guidelines of the Federation of European Laboratory Animal Science Associations (FELASA). Healthy adult animals 8-12 weeks old, both male and female were used in studies. All experiments were performed using age- and sex-matched littermate controls. If possible, mice were allocated randomly into groups by a computer-based random number generator ( http://www.randomizer.org ), so that each cage contained animals of every group to compensate for possible cage effects. Power analysis was performed before begin of the experiments on the basis of effect size estimates from previous experience.
