Phospholipid Bilayer-Coated Aluminum Nanoparticles as an Effective Vaccine Adjuvant-Delivery System

The <i>p</i>hospho<i>l</i>ipid bilayer-coated <i>a</i>luminum <i>n</i>anoparticles (PLANs), formed via chemisorption, were prepared by reverse ethanol injection-lyophilization (REIL) utilizing the phosphophilicity of aluminum. The anhydrous antigen-loaded PLANs obtained by REIL proved stable, satisfying using the controlled-temperature-chain instead of the integrated cold-chain for distribution, and could be rehydrated to reconstitute instantly an aqueous suspension of the antigen-PLANs, which were more readily taken up by antigen-presenting cells and, when given subcutaneously to mice, induced more robust antigen-specific humoral and cellular immunoresponses but less local inflammation than the antigen-alum. Thus, the PLANs are a useful vaccine adjuvant-delivery system with advantages over the widely used naked alum

Additional file 1: of Naringin ameliorates the high glucose-induced rat mesangial cell inflammatory reaction by modulating the NLRP3 Inflammasome

Key summary points. Diabetic kidney disease (DKD) is one of the most serious chronic complications of diabetes mellitus (DM), is a strong risk factor for cardiovascular diseases, and is a major cause of end stage kidney disease. The pathogenesis of DKD is complex and there are no effective measures to treat it currently.The aim of this study was to investigate the expression of the NLRP3-inflammasome under high glucose conditions, the effects of naringin during these conditions, and elucidate the role of naringin in the pathogenesis of DKD. Our results confirmed that naringin can regulate the NLRP3-Caspase-1-IL-1β / IL-18 signaling pathway by the NLRP3 inflammasome, which can improve DKD by playing an anti-inflammatory role.This study provides new insights into the nephroprotective mechanism of naringin to improve DKD by anti-inflammatory responses.

Synthesis and Characterization of Novel 1,4-Bis(carbazolyl)benzene Derivatives with Blue-Violet Two-Photon-Excited Fluorescence

Novel fluorescent two-photon absorption molecules containing bis­(carbazolyl)­benzene as the central unit and phenylethynyl moieties as peripheral groups (Cz-Ps) are synthesized and characterized. In these molecules, two carbazolyl moieties are linked with benzene at the 9-position and synthesized by a concise process involving nucleophilic substitution between the cyclopentadienyliron complexes of dichloroarenes and phenylethynyl carbazole, followed by photolysis. The optimal structures of Cz-Ps reveal that two carbazolyl rings linked by a benzene ring are not planar. This feature prevents the electron conjugation of the molecule from extending throughout the whole molecule and allows Cz-Ps to realize blue-violet emissions and high fluorescence quantum yield. With increasing number of conjugated phenylacetylene structures in Cz-Ps, the maximal absorption and emission peaks were red-shifted. The quadrupolar compound DMoCz-P shows strong one-photon and two-photon activities. The resulting molecules are also thermally stable with high glass transition temperatures due to the rigid bicarbazole central unit. This work has demonstrated that using bis­(carbazolyl)­benzene as central building block could enhance two-photon absorption (TPA) performance and also provides a possible general synthetic strategy for a series of bis­(carbazolyl)­benzene derivatives, which would advance the understanding of the rational design of new organic optical materials
