Rationally Engineering Pro-Proteins and Membrane-Penetrating α‑Helical Polypeptides for Genome Editing Toward Choroidal Neovascularization Treatment.

Ribonucleoprotein (RNP)-based CRISPR/Cas9 genome editing holds great potential for the treatment of choroidal neovascularization (CNV), which however, is challenged by the lack of efficient cytosolic protein delivery tools. Herein, reversibly-phosphorylated pro-proteins (P-proteins) with conjugated adenosine triphosphate (ATP) tags are engineered and coupled with a membrane-penetrating, guanidine-enriched, α-helical polypeptide (GP) to mediate robust and universal cytosolic delivery. GP forms salt-stable nanocomplexes (NCs) with P-proteins via electrostatic interaction and salt bridging, and the helix-assisted, strong membrane activities of GP enabled efficient cellular internalization and endolysosomal escape of NCs.

Dynamic phase transitions dictate the size effect and activity of supported gold catalysts.

The landmark discovery of gold catalysts has aroused substantial interest in heterogeneous catalysis, yet the catalytic mechanism remains elusive. For carbon monoxide oxidation on gold nanoparticles (NPs) supported on ceria surfaces, it is widely believed that carbon monoxide adsorbs on the gold particles, while the reaction occurs at the gold/ceria interface. Here, we have investigated the dynamic changes of supported gold NPs with various sizes in a carbon monoxide oxidation atmosphere using deep potential molecular dynamics simulations.

A Room-Temperature Terahertz Photodetector Imaging with High Stability and Polarization-Sensitive Based on Perovskite/Metasurface.

Terahertz (THz) polarization detection facilitates the capture of multidimensional data, including intensity, phase, and polarization state, with broad applicability in high-resolution imaging, communication, and remote sensing. However, conventional semiconductor materials are limited by energy band limitations, rendering them unsuitable for THz detection. Overcoming this challenge, the realization of high-stability, room-temperature polarization-sensitive THz photodetectors (PDs) leveraging the thermoelectric effect of Cs(FAMA)Pb(IBr) (CsFAMA)/metasurfaces is presented.

Serotonin neurons integrate GABA and dopamine inputs to regulate meal initiation.

Obesity is a growing global health epidemic with limited orally administered therapeutics. Serotonin (5-HT) is one neurotransmitter which remains an excellent target for new weight-loss therapies, but a gap remains in understanding the mechanisms involved in 5-HT produced in the dorsal Raphe nucleus (DRN) and its involvement in meal initiation. Using an optogenetic feeding paradigm, we showed that the 5-HT➔arcuate nucleus (ARH) circuit plays a role in meal initiation.

Group graph: a molecular graph representation with enhanced performance, efficiency and interpretability.

The exploration of chemical space holds promise for developing influential chemical entities. Molecular representations, which reflect features of molecular structure in silico, assist in navigating chemical space appropriately. Unlike atom-level molecular representations, such as SMILES and atom graph, which can sometimes lead to confusing interpretations about chemical substructures, substructure-level molecular representations encode important substructures into molecular features; they not only provide more information for predicting molecular properties and drug‒drug interactions but also help to interpret the correlations between molecular properties and substructures.
