Towards effective functionalization of nanopores/nanochannels: the role of amidation reactions.

Chem Commun (Camb)

January 2025

State Key Laboratory of Biogeology and Environmental Geology, Engineering Research Center of Nano-Geomaterials of Ministry of Education, Faculty of Materials Science and Chemistry, China University of Geosciences, Wuhan 430074, China.

In recent years, researchers have drawn inspiration from natural ion channels to develop various artificial nanopores/nanochannels, including solid-state and biological. Through imitating the precise selectivity and single molecule sensing exhibited by natural ion channels, nanopores/nanochannels have been widely used in many fields, such as analyte detection, gene sequencing and so on. In these applications, the surface functionalization of nanopores/nanochannels directly determines the effectiveness in quantitative analysis and single molecule detection.

Despite identifying specific CD8 T cell subsets associated with immunotherapy resistance, the molecular pathways driving this process remain elusive. Given the potential role of CD38 in regulating CD8 T cell function, we aimed to investigate the accumulation of CD38CD8 T cells in lung cancer and explore its role in immunotherapy resistance. Phenotypic analysis of tumoral CD8 T cells from both lung cancer patients and immunotherapy-resistant preclinical models revealed that CD38-expressing CD8 T cells consist of CD38 and CD38 subsets.

Alzheimers Dement

December 2024

Shenzhen Bay Laboratory, Shenzhen, Guandong, China.

Background: The classic mode of STING activation is through binding the cyclic dinucleotide 2'3'-cyclic GMP-AMP (cGAMP), produced by the DNA sensor cyclic GMP-AMP synthase (cGAS), which is important for the innate immune response to microbial infection and autoimmune disease. Modes of STING activation that are independent of cGAS are much less well understood. We wanted to explore the interactome of STING on the organelles during its trafficking route and to understand the regulatory network of STING signaling.

Background: The mesolimbic system plays a crucial role in weight regulation and cognition. Previous studies suggest that the pathology of Alzheimer's disease (AD) can lead to the atrophy of the mesolimbic system and body mass index (BMI) decline. It remains unknown whether BMI is associated with the the mesolimbic system in AD.

NG-497 Alleviates Microglia-Mediated Neuroinflammation in a MTNR1A-Dependent Manner.

Inflammation

January 2025

Department of Neurology, Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, China.

Microglia-mediated neuroinflammation plays a crucial role in multiple neurological diseases. We have previously found that Atglistatin, the mouse Adipose Triglyceride Lipase (ATGL) inhibitor, could promote lipid droplets (LDs) accumulation and suppress LPS-induced neuroinflammation in mouse microglia. However, Atglistatin was species-selective, which limited its use in clinical settings.

Radiation therapy for childhood-onset craniopharyngioma: systematic review and meta-analysis.

J Neurooncol

January 2025

Department of Endocrinology, Genetics and Metabolism, Beijing Children's Hospital, National Center for Children's Health, Capital Medical University, Beijing, 100045, China.

Background: Craniopharyngioma (CP), a benign tumor originating from remnants of Rathke's pouch in the sellar region, accounts for approximately 30% of all cases of craniopharyngioma. Radiation therapy has been used to treat CP patients for decades; however, there is still a lack of systematic reviews on the long-term tumor control outcomes in pediatric CP patients treated with external radiation therapy.

Methods: We conducted a comprehensive search of multiple databases for studies on the tumor progression rates of childhood-onset CP(COCP) patients who received external radiotherapy.
