Discovering Multi-Compositional Li-Argyrodite Solid-State Electrolytes via Experimental Active Learning.

Significant research has focused on doping third-party elements into representative Li-Argyrodites, which typically consist of a metal cation, a sulfide anion, and a halide. These efforts have generally been limited to doping or substituting a single element at each atomic site in the Argyrodite structure, resulting in, at most, binary combinations at each site. Multi-elemental doping or substitution poses a challenge due to the so-called combinatorial explosion issue.

Rational Design of an Activatable Near-Infrared Fluorogenic Platform for In Vivo Orthotopic Tumor Imaging and Resection.

A Renal Clearable Nano-Assembly with Förster Resonance Energy Transfer Amplified Superoxide Radical and Heat Generation to Overcome Hypoxia Resistance in Phototherapeutics.

Given that type I photosensitizers (PSs) possess a good hypoxic tolerance, developing an innovative tactic to construct type I PSs is crucially important, but remains a challenge. Herein, we present a smart molecular design strategy based on the Förster resonance energy transfer (FRET) mechanism to develop a type I photodynamic therapy (PDT) agent with an encouraging amplification effect for accurate hypoxic tumor therapy. Of note, benefiting from the FRET effect, the obtained nanostructured type I PDT agent (NanoPcSZ) with boosted light-harvesting ability not only amplifies superoxide radical (O ) production but also promotes heat generation upon near-infrared light irradiation.

Pharmacological inhibition of AIMP2 aggregation attenuates α-synuclein aggregation and toxicity in Parkinson's disease.

The aggregation of aminoacyl transfer RNA synthetase complex-interacting multifunctional protein-2 (AIMP2) accelerates α-synuclein aggregation via direct interaction, leading to enhanced dopaminergic neurotoxicity in Parkinson's disease (PD). Thus, it would be beneficial to prevent AIMP2 aggregation to suppress α-synucleinopathy in PD. In this study, we screened small compounds that could inhibit the in vitro aggregation of AIMP2 using a 1909 small-compound library.

HMGB1 increases RAGE expression in vascular smooth muscle cells ERK and p-38 MAPK-dependent pathways.

The increased expression of receptors for advanced glycation end-product (RAGE) is known as a key player in the progression of vascular remodeling. However, the precise signal pathways regulating RAGE expression in vascular smooth muscle cells (VSMCs) in the injured vasculatures are unclear. Given the importance of mitogen-activated protein kinase (MAPK) signaling in cell proliferation, we investigated the importance of MAPK signaling in high-mobility group box 1 (HMGB1)-induced RAGE expression in VSMCs.

Tumor Selective Metabolic Reprogramming as a Prospective PD-L1 Depression Strategy to Reactivate Immunotherapy.

Currently, the role of the lysosome, endoplasmic reticulum, or dictyosome in the transcription and translation of programmed cell death ligand 1 (PD-L1) is well revealed, but the role and function of mitochondria in the PD-L1 expression in tumors is still not fully researched, making it hard to offer a novel PD-L1 regulation strategy. In this research, it is newly revealed that mitochondria oxidative phosphorylation (OXPHOS) depression can be used as an effective PD-L1 down-regulation method. To offer an ideal and high-effective tumor mitochondria-targeted OXPHOS depression nanosystem, IR-LND is prepared by conjugating mitochondria-targeted heptamethine cyanine dye IR-68 with mitochondrial complexes I and II depression agent lonidamine (LND), which then further self-assembled with albumin (Alb) to form IR-LND@Alb nanoparticles.

Synthetic Peucedanocoumarin IV Prevents α-Synuclein Neurotoxicity in an Animal Model of Parkinson's Disease.

Pathological protein inclusion formation and propagation are the main causes of neuronal dysfunction in diverse neurodegenerative diseases; therefore, current disease-modifying therapeutic strategies have targeted this disease protein aggregation process. Recently, we reported that peucedanocoumarin III (PCiii) is a promising therapeutic compound with the ability to disaggregate α-synuclein inclusion and protect dopaminergic neurons in Parkinson's disease (PD). Here, we found that -4'-acetyl-3'-tigloylkhellactone (racemic peucedanocoumarin IV [PCiv]), a structural isomer of PCiii with a higher synthetic yield presented a strong anti-aggregate activity to a degree comparable to that of PCiii.
