However, developing nanomedicines that can cure autoimmune diseases without causing systemic immunosuppression is still quite challenging. Herein, we propose an all-in-one nanomedicine comprising an autoantigen peptide and CRISPR-Cas9 to restore specific immune tolerance by engineering dendritic cells (DCs) into a tolerogenic phenotype, which can expand autoantigen-specific regulatory T (Treg) cells. In brief, we utilized cationic lipid-assisted poly(ethylene glycol)-b-poly(lactide-co-glycolide) (PEG-PLGA) nanoparticles to simultaneously encapsulate an autoimmune diabetes-relevant peptide (2.5mi), a CRISPR-Cas9 plasmid (pCas9), and three guide RNAs (gRNAs) targeting costimulatory molecules (CD80, CD86, and CD40). We demonstrated that the all-in-one nanomedicine was able to effectively codeliver these components into DCs, followed by simultaneous disruption of the three costimulatory molecules and presentation of the 2.5mi peptide on the genome-edited DCs. The resulting tolerogenic DCs triggered the generation and expansion of autoantigen-specific Treg cells by presenting the 2.5mi peptide to CD4+ T cells in the absence of costimulatory signals. Using autoimmune type 1 diabetes (T1D) as a typical disease model, we demonstrated that our nanomedicine prevented autoimmunity to islet components and inhibited T1D development. Our all-in-one nanomedicine achieved codelivery of CRISPR-Cas9 and the peptide to DCs and could be easily applied to other autoimmune diseases by substitution of different autoantigen peptides.Breeding and engineering of biofortified crops will benefit from a better understanding of bottlenecks controlling micronutrient loading within the seeds. However, few studies have addressed the changes in micronutrient concentrations, localization, and speciation occurring over time. Therefore, we studied spatial patterns of zinc and iron accumulation during grain development in two barley lines with contrasting grain zinc concentrations. Microparticle-induced-X-ray emission and laser ablation-inductively coupled plasma mass spectrometry were used to determine tissue-specific accumulation of zinc, iron, phosphorus, and sulfur. Differences in zinc accumulation between the lines were most evident in the endosperm and aleurone. A gradual decrease in zinc concentrations from the aleurone to the underlying endosperm was observed, while iron and phosphorus concentrations decreased sharply. Iron co-localized with phosphorus in the aleurone, whereas zinc co-localized with sulfur in the sub-aleurone. We hypothesize that differences in grain zinc are largely explained by the endosperm storage capacity. Engineering attempts should be targeted accordingly.Sodium citrate (Na3Cit) has a crucial role in many biological and industrial processes. Yet, quantitative information on its hydration and the ion association between Na+ and Cit3- ions in a broad range of salt concentrations is still lacking. In this work, we study both ion association equilibria and relaxation dynamics of sodium citrate solutions by combining potentiometry, spectrophotometry, and dielectric spectroscopy. From photometric and potentiometric measurements, we detect the formation of the NaCit2- ion-pair and the neutral Na3Cit0 ion aggregate in a wide range of ionic strengths (0.5-4 M). Due to its remarkable stability, the latter becomes the prevailing species at higher salt concentrations. In the dielectric spectra, we observe the dipolar relaxation of Cit3- and NaCit2- and two solvent-related processes, associated with the collective rearrangement of the H-bond network (cooperative water mode) and the H-bond flip of water molecules (fast water mode). Unlike numerous other salt solutions, the relaxation time of the cooperative mode scales with the viscosity indicating that the strongly hydrated anion fits well into the water network. That is, the stabilizing effect of anion-solvent interactions on the H-bond network outweighs the destructive impact of the cations as the latter are only present at low concentration, due to strong ion association. In conclusion, the affinity of citrate toward Na+ binding not only governs solution equilibria but also has a strong impact on water dynamics.Ligands for cereblon, a component of a functional E3 ligase complex that targets proteins for proteolysis, are critical for developing molecular glues and proteolysis-targeting chimeras (PROTACs), which have therapeutic implications for various diseases. However, the lack of sensitivity of previously reported assays limits characterization of cereblon ligands. To address this shortcoming, we developed BODIPY FL thalidomide (10) as a high-affinity fluorescent probe for the human cereblon protein, with a Kd value of 3.6 nM. We then used BODIPY FL thalidomide (10) to develop a cereblon time-resolved fluorescence resonance energy transfer (TR-FRET) binding assay. The IC50 values of the cereblon ligand pomalidomide (8) were 6.4 nM in our cereblon TR-FRET binding assay, 264.8 nM in a previously reported Cy5-conjugated thalidomide (7)-mediated fluorescence polarization (FP) assay, and 1.2 μM in a previously reported Cy5-conjugated cereblon modulator (compound 7) (9)-mediated TR-FRET assay, indicating that our cereblon TR-FRET binding assay is 41- and 187-fold more sensitive than these two previously published assays. With our cereblon TR-FRET binding assay, we detected binding of cereblon ligands but not binding of bromodomain-containing protein 4 or von Hippel-Lindau ligands, thereby demonstrating its selectivity. Our cereblon TR-FRET binding assay was very stable and detected changes in phthalimide activity due to thalidomide isomerization. Therefore, the BODIPY FL thalidomide (10)-mediated cereblon TR-FRET binding assay we designed is highly sensitive, selective, and stable and will aid the development and characterization of novel cereblon ligands.We have developed cyclodextrin-catalyzed lipid exchange methods to prepare large unilamellar vesicles (LUVs) with asymmetric charge distributions, i.e., with different net charges on the lipids in the inner and outer leaflets. LUVs contained a mixture of a zwitterionic lipid (phosphatidylcholine), cholesterol, and various cationic lipids (O-ethyl phosphatidylcholine or dioleoyl-3-trimethylammonium propane) or anionic lipids (phosphatidylglycerol, phosphatidylserine, or phosphatidic acid). Symmetric and asymmetric LUVs with a wide variety of lipid combinations were prepared. The asymmetric LUVs contained cationic or anionic outer leaflets and inner leaflets that had either the opposite charge or were uncharged. The behavior of symmetric LUVs prepared with zwitterionic, anionic, or cationic leaflets was compared to those of asymmetric LUVs. Lipid exchange was confirmed by quantitative thin-layer chromatography, and lipid asymmetry by a novel assay measuring binding of a cationic fluorescent probe to the LUV outer leaflet. For both symmetric and asymmetric LUVs, the level of entrapment of the cationic drug doxorubicin was controlled by the charge on the inner leaflet, with the greatest entrapment and slowest leakage in vesicles with an anionic inner leaflet. This shows that it is possible to choose inner leaflet lipids to maximize liposomal loading of charged drugs independently of the identity of outer-leaflet lipids. This implies that it should also be possible to independently vary outer-leaflet lipids to, for example, impart favorable bioavailability and biodistribution properties to lipid vesicles.Surface biofunctionalization provides an approach to the fabrication of surfaces with improved biological and clinical performances. Biosurfaces have found increasing applications in many areas such as sensing, cell growth, and disease detection. Efficient synthesis of biosurfaces without damages to the structures and functionalities of biomolecules is a great challenge. Polymerization-induced surface self-assembly (PISSA) provides an effective approach to the synthesis of surface nanostructures with different compositions, morphologies, and properties. In this research, application of PISSA in the fabrication of biosurfaces is investigated. Two different reversible addition-fragmentation chain transfer (RAFT) agents, RAFT chain transfer agent (CTA) on silica particles (SiO2-CTA) and CTA on bovine serum albumin (BSA-CTA), were employed in RAFT dispersion polymerization of N-isopropylacrylamide (NIPAM) in water at a temperature above the lower critical solution temperature (LCST) of poly-(isopropylacrylamide) en PNIPAM and BSA. Based on this approach, many different biosurfaces can be fabricated and the materials will find applications in many fields, such as enzyme immobilization, drug delivery, and tissue engineering.Wet NH4-N deposition plays a significant role in the ecosystem safety in China, and thus it is highly imperative to estimate the national wet NH4-N deposition flux accurately. In this study, a new methodology named space-time ensemble machine-learning model was first applied to constrain the high-resolution NH4-N deposition fluxes over China based on the satellite data, assimilated meteorology, and various geographical covariates. A small gap between site-based cross-validation (CV) R2 value (0. 73) and 10-fold CV R2 value (0.76), along with remarkable improvement in predictive accuracy (0.76) compared with previous studies (0.61), demonstrated the strong prediction capability of the space-time ensemble model in data mining. read more The higher wet NH4-N deposition fluxes mainly occurred in North China Plain (NCP), Sichuan Basin, Hunan, Jiangxi, and Guangdong provinces, whereas other regions retained the lower values. In addition, the wet NH4-N deposition fluxes, removing the precipitation effect in some major developed regions (e.g., Beijing and Shanghai) of China, displayed gradual increases from 2011 to 2014, while they suffered from dramatic decreases during 2014-2016, which was due to the strict implementation of the Action Plan for Air Pollution Prevention and Control (APPC-AP). The high-quality NH4-N deposition data sets are greatly useful to assess the potential ecological risks.1,8-Naphthalimide-based imidazolium salts differing for the alkyl chain length and the nature of the anion were synthesized and characterized to obtain fluorescent probes for bioimaging applications. First, their self-assembly behavior and gelling ability were investigated in water and water/dimethyl sulfoxide binary mixtures. Only salts having longer alkyl chains were able to give supramolecular hydrogels, whose properties were investigated by using a combined approach of fluorescence, resonance light scattering, and rheology measurements. Morphological information was obtained by scanning electron microscopy. In addition, conductive properties of organic salts in solution and gel state were analyzed. Imidazolium salts were successfully tested for their possible application as bioimaging and cytotoxic agents toward three cancer cell lines and a nontumoral epithelial cell line. Characterization of their behavior was performed by MTT and cell-based assays. Finally, the biological activity of hydrogels was also investigated.
