We showed that in models of autoimmunity and transplant rejection, adoptive transfer of antigen specific 3C-iTregs prevented the induction of EAE and enabled long-term skin allograft survival. Our data demonstrate that the Foxp3 locus can be epigenetically edited ex vivo to generate stable therapeutic iTregs. This article is protected by copyright.

Immobilization- and label-free analytical techniques are particular desirable because of their simplicity and minimal invasiveness, but struggle to quantify tight interactions. Here, we show that we can accurately count, distinguish by molecular mass, and thereby reveal the relative abundances of different un-labelled biomolecules and their complexes in mixtures at the single-molecule level by mass photometry. These measurements enable us to quantify binding affinities over four orders of magnitude at equilibrium for both simple and complex stoichiometries within minutes, as well as to determine the associated kinetics. Our results introduce mass photometry as a rapid, simple and label-free method for studying sub-µM binding affinities, with potential to be extended towards a universal approach for characterising complex biomolecular interactions. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The present study evaluated the bond strengths of prefabricated PolyEtherKetoneKetone (PEKK) posts, PEKK posts custom-configured according to root-canal size, and conventional fiber posts. A total of 30 maxillary incisors were randomly divided into three groups, as follows Group 1 fiber posts; Group 2 prefabricated PEKK posts; Group 3; custom-made PEKK posts. Following endodontic treatment, post spaces were prepared, and posts were cemented with resin cement. Push-out bond strength testing was performed using a universal testing machine, and fractures modes were examined under a scanning electron microscope. Data were analyzed using One-way ANOVA and Tukey's HSD tests, with the level of significance set at .05. The highest bond-strength values in the cervical section were observed with the custom-made PEKK post (17.3470 MPa), whereas the highest bond-strength values in the middle and apical sections were observed with the conventional fiber posts (11.5375 MPa and 6.8625 MPa, respectively). Bond-strength values for all posts systems decreased in a cervical to apical direction. PTC-209 BMI-1 inhibitor PEKK posts are a suitable alternative to fiber posts. Although custom-made PEKK posts demonstrated better bond strength than prefabricated PEKK posts, further studies are needed to evaluate their clinical performance. © 2020 Wiley Periodicals, Inc.AIMS To assess the effect of peer support intervention on diabetes distress in people with type 2 diabetes. BACKGROUND Diabetes distress may be decreased by peer support intervention, but findings about the effect of peer support on diabetes distress have been mixed. DESIGN A systematic review and meta-analysis of randomized controlled studies. DATA SOURCES PubMed, Embase, CENTRAL, PsycINFO, Web of Science, and CINAHL databases were searched for randomized controlled trials from inception to 30 June 2018. REVIEW METHODS Investigators assessed eligibility, extracted data, and assessed methodological quality. Standardized mean difference and 95% confidence intervals were calculated for pooled effect size. RESULTS A total of 13 studies included in systematic review and 10 in meta-analysis. In the random-effects model, the pooled effect size showed current peer support intervention did not significantly reduce diabetes distress in type 2 diabetes population compared with usual care. CONCLUSION High quality and well-designed studies targeting at reducing diabetes distress are needed to further test the effect of peer support intervention on diabetes distress. © 2020 John Wiley & Sons Australia, Ltd.Intimal injury is an early stage of several cardiovascular diseases. Endothelial progenitor cells (EPCs) play a significant role in endothelial repair following vascular injury. Once the intima is damaged, EPCs are mobilized from the bone marrow to the injury site. Meanwhile, the injury to the intimal surface triggers platelet degranulation, aggregation, and adhesion to the damaged endothelium, and exposed collagen stimulates platelet to secrete platelet-derived microvesicles (PMVs). However, the role of PMVs in EPC function during this process remains unknown. In an in vivo study, EPCs and platelets were found to adhere to the injury site in Sprague-Dawley (SD) rat vascular injury model. In vitro, collagen stimulation induced the release of PMVs, and collagen-activated PMVs (ac.PMVs) significantly promoted EPC proliferation. Transforming growth factor-β1 (TGF-β1) content was increased in ac.PMVs. Activated PMVs significantly upregulated Smad3 phosphorylation in EPCs and increased Smad3 nuclear translocation from the cytoplasm. TGF-β1 knockdown ac.PMVs downregulated EPC proliferation. Recombinant TGF-β1 enhanced EPC proliferation. The TGF-β1 inhibitor SB431542 significantly repressed the intracellular signal triggered by ac.PMVs. Furthermore, the Smad3-specific phosphorylation inhibitor SIS3 effectively reversed the cell proliferation induced by ac.PMVs. Smad3 translocated to the nucleus and enhanced EPC proliferation via its downstream genes tenascin C (TNC), CDKN1A, and CDKN2A. r-TGF-β1 promoted reendothelialization and EPC proliferation in vivo. Our data demonstrate that activated PMVs deliver TGF-β1 from collagen-activated platelets to EPCs, which in turn activates Smad3 phosphorylation and regulates TNC, CDKN1A, and CDKN2A expression to promote EPC proliferation, suggesting that PMVs act as a key transporter and a potential therapeutic target for vascular injury. © 2020 Federation of European Biochemical Societies.OBJECTIVE To determine if there is an increased risk of dementia among patients with overactive bladder (OAB) starting an anticholinergic medication compared to those starting a beta-3 agonist. METHODS We conducted a population-based, retrospective, matched cohort study using linked administrative data from Ontario, Canada from 2010 to 2018. We matched 47 324 new users of anticholinergic medications (oxybutynin, tolterodine, solifenacin, darifenacin, fesoterodine, trospium) to 23 662 new users of a beta-3 agonist medication (mirabegron); all of the included medications are only indicated for the treatment of OAB. We measured 75 baseline variables (including comorbid conditions, recent medications, and prior healthcare utilization) and used these to create a propensity score; groups were similar across all measured variables after matching. The primary exposure was the class of OAB medication (anticholinergic or beta-3 agonist). The primary outcome was dementia using a validated administrative data definition.
