Dopamine Receptor 1 Impedes ILC2-Mediated Antitumor Immunity.

Ever-growing evidence has revealed that group 2 innate lymphoid cells (ILC2s) exhibit pleiotropic effects in antihelminth immunity, allergy, tissue protection, and cancer. Currently, the role of ILC2s in cancer is highly controversial regarding the intricate tumor microenvironment (TME), and the tumor-promoting or antitumor immunological mechanisms of ILC2s remain largely unknown. In this study, we report that dopamine receptor 1 (DRD1) restrains ILC2 activity in the TME.

A light-driven photoelectrochemical sensor for highly selective detection of hydroquinone based on type-II heterojunction formed by carbon nanotubes immobilized in 3D honeycomb CdS/SnS.

The ecological environment and public safety are seriously threatened by the typical phenolic contaminant hydroquinone (HQ). Here, using a straightforward physical mixing technique, we created an n-n heterojunction by uniformly immobilizing cadmium sulfide (CdS) nanoparticles on the surface of a three-dimensionally layered, flower-like structure made of tin sulfide (SnS). Then, as photosensitizers, carbon nanotubes (CNTs) were added to the CdS/SnS complex to create a type-II heterostructure of CdS/SnS/CNTs with synergistic effects.

An ultrasensitive high-performance baicalin sensor based on CN-SWCNTs/reduced graphene oxide/cyclodextrin metal-organic framework nanocomposite.

Baicalin (Bn) obtained from natural plants has been found to exhibit significant antiviral activity against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Herein, a novel ultrasensitive Bn electrochemical sensor was proposed based on graphitized carbon-nitride - single-walled carbon nanotube nanocomposites (CN-SWCNTs), reduced graphene oxide (rGO) and electrodeposited cyclodextrin-metal organic framework (CD-MOF). The sensing nanomaterials were characterized by X-ray diffraction spectroscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy.

Ultrasensitive catechin electrochemical sensor based on uniform ordered mesoporous carbon hollow spheres (MCHSs) advanced carbon-based conductive materials.

Catechin is one of the flavonoids with antioxidant activity and has attracted great interest. A rapid and accurate detection of catechin is of great significance. Herein, an ultrasensitive catechin electrochemical sensor based on uniform ordered mesoporous carbon hollow spheres (MCHSs) advanced carbon-based conductive material modified glass carbon electrode was constructed.
