Tuning Surface Valences of Nanoengagers to Enhance Their Structural Advantages for Efficiently Redirecting T Cells against Solid Tumors.

The nanoengager strategy, which enhances receptor signaling responsiveness through a multivalent ligand binding mode, offers a promising approach for improving immune cell redirecting therapy. Increasing nanomaterial platforms have been developed for constructing more flexible and multifunctional nanoengagers, but the different mediating mechanisms from their multivalent nanostructures, compared to original monomolecule engagers, have rarely been discussed. Here, we constructed dual-specificity T cell nanoengagers (TNEs) targeting CD3 and PDL1 receptors based on a polyethylene glycol--polylactic acid (PEG--PLA)-assembled nanoparticle and specifically studied the impact of surface antibody valences on their functional mechanisms, thereby enhancing the structural advantages of TNEs against solid tumors.

Multicolor and sign-invertible circularly polarized luminescence from nonchiral charge-transfer complexes assembled with N-terminal aromatic amino acids.

Circularly polarized luminescence (CPL) materials with precisely controlled emission colors and handedness are highly desirable for their promising applications in advanced optical technologies, but it is rather challenging to obtain them primarily due to the lack of convenient, powerful, and universal preparation strategies. Herein, we report a simple yet versatile solution route for constructing multicolor CPL materials with controllable handedness from nonchiral luminescent charge-transfer (CT) complexes through co-assembly with chiral N-terminal aromatic amino acids. The resulting ternary co-assemblies exhibit obvious CPL signals from 489 to 601 nm, covering from blue green and yellow to orange-red.

Intestinal Subtype as a Biomarker of Response to Neoadjuvant Immunochemotherapy in Locally Advanced Gastric Adenocarcinoma: Insights from a Prospective Phase II Trial.

Purpose: Neoadjuvant immunochemotherapy (NAIC) markedly induces pathologic regression in locally advanced gastric adenocarcinoma. However, specific biomarkers are still lacking to effectively identify the beneficiary patients for NAIC.

In Situ Constructing Ultrafast Ion Channel for Promoting High-Rate Cycle Stability of Nano-NaV(PO) Cathode.

Encapsulating nanomaterials in carbon is one of the main ways to increase the cathode stability, but it is difficult to simultaneously optimize the rate capacity and enhance durability derived from the insufficient ion transport channels and deficient ion adsorption sites that constipate the ion transport and pseudocapacitive reaction. Herein, we develop the ligand-confined growth strategy to encapsulate the nano-NaV(PO) cathode material in various carbon channels (microporous, mesoporous, and macroporous) to discriminate the optimal carbon channels for synchronously improving rate capacity and holding the high-rate cycle stability. Benefiting from the unobstructed ion/charge transport channels and flexible maskant created by the interconnected mesoporous carbon channels, the prepared NaV(PO) nanoparticles confined in mesoporous carbon channel (Mes-NVP/C) achieve a discharge-specific capacity of 70 mAh g even at the ultrahigh rate of 100 C, higher than those of the NaV(PO) nanoparticles confined in microporous and macroporous carbon channel (Micr-NVP/C and Macr-NVP/C), respectively.
