PD1-TLR10 fusion protein enhances the antitumor efficacy of CAR-T cells in colon cancer.

Background: The immunosuppressive microenvironment negatively affects the efficacy of chimeric antigen receptor T (CAR-T) cells in solid tumors. Fusion protein that combining extracellular domain of inhibitory checkpoint protein and the cytoplasmic domain of stimulatory molecule may improve the efficacy of CAR-T cells by reversing the suppressive signals.

Methods: To generate optimal PD1-TLR10 fusion proteins, PD1 extracellular domain and TLR10 intracellular domain were connected by transmembrane domain from PD1, CD28, or TLR10, respectively.

Identification of SETD4 as an Onco-Immunological Biomarker Encompassing the Tumor Microenvironment, Prognoses, and Therapeutic Responses in Various Human Cancers.

Background: SET domain-containing protein 4 (SETD4) is a histone methyltransferase that has been shown to modulate cell proliferation, differentiation, and inflammatory responses by regulating histone H4 trimethylation (H4K20me3). Previous reports have demonstrated its function in the quiescence of cancer stem cells as well as drug resistance in several cancers. A limited number of systematic studies have examined SETD4's role in the tumor microenvironment, pathogenesis, prognosis, and therapeutic response.

Prognostic Value of D-Dimer in Acute Type A Aortic Dissection and Intramural Hematoma: Observations from the Acute Aortic Syndrome Group of the Registry of Acute Non-Traumatic Chest Pain in China.

Background: Acute type A aortic dissection (AAD) and acute type A intramural hematoma (AIMH) are life-threatening conditions with high mortality rates, and prognostic indicators are critical for guiding urgent treatment decisions. We assessed the prognostic significance of admission D-dimer levels in patients with AAD and AIMH.

Methods And Results: The prospective, multicenter, observational study in China recruited participants from 2013 to 2019.

Oxygen, light, and mechanical force mediated radical polymerization toward precision polymer synthesis.

The synthesis of polymers with well-defined composition, architecture, and functionality has long been a focal area of research in the field of polymer chemistry. The advancement of controlled radical polymerization (CRP) has facilitated the synthesis of precise polymers, which are endowed with new properties and functionalities, thereby exhibiting a wide range of applications. However, radical polymerization faces several challenges, such as oxygen intolerance, and common thermal initiation methods may lead to side reactions and depolymerization.

Synergistic Cu(II)/Amine-Catalyzed Cyclization of Enynone: Assembly of Tetralone and Tetrahydronaphthylimine.

An unprecedented synergistic copper- and amine-catalyzed cyclization of enynone is reported. This reaction features an efficient and straightforward construction of multisubstituted tetralone through an amine-assisted regioselective oxygen atom transfer process and stereoselective intramolecular Michael addition cyclization. Under dehydrative reaction conditions, the synthesis of tetrahydronaphthylimine derivatives with ketone group tolerance is achieved, which could be challenging via traditional methods.
