Transketolase Promotes MAFLD by Limiting Inosine-Induced Mitochondrial Activity

Background Introduction Metabolic dysfunction-associated fatty liver disease (MAFLD) is a globally prevalent chronic liver disease with an incidence rate of about 25%. Its prevalence is even higher among obese and type 2 diabetic populations. MAFLD is a complex systemic disease that can progress from metabolic-associated fatty liver (MAFL) to metab...

Glucagon-like peptide 1 receptor is a T cell-negative costimulatory molecule

Role of GLP-1R in T Cells and Its Regulatory Mechanism for Anti-transplant Immunity and Anti-tumor Immunity Academic Background Glucagon-like peptide-1 receptor (GLP-1R) is known as a key regulator of glucose metabolism, primarily expressed in pancreatic β cells. Previous studies have clarified that GLP-1R agonists have significant effects in reduc...

QDPR Deficiency Drives Immune Suppression in Pancreatic Cancer

Background Pancreatic Ductal Adenocarcinoma (PDAC) is a malignancy with a highly immunosuppressive tumor microenvironment (TME), showing strong resistance to immune checkpoint blockade (ICB) therapies, such as anti-PD-1 and anti-CTLA-4 treatments. Myeloid-Derived Suppressor Cells (MDSCs) derived from tumors play a critical role in tumor immune supp...

Acetyl-CoA Carboxylase Obstructs CD8+ T Cell Lipid Utilization in the Tumor Microenvironment

Inhibition of Acetyl-CoA Carboxylase Enhances Antitumor Immunity of Tumor-Infiltrating CD8+ T Cells Background and Objective In recent years, the impact of metabolic changes in the Tumor Microenvironment (TME) on the function of Tumor-Infiltrating Lymphocytes (TILs) has become a hot topic in immunological research. Although T cells possess strong a...

Glycometabolic Reprogramming-Induced XRCC1 Lactylation Confers Therapeutic Resistance in ALDH1A3-Overexpressing Glioblastoma

Background Glioblastoma (GBM) is the most common and aggressive malignant primary brain tumor in adults, characterized by high recurrence and mortality rates. Despite active chemotherapy and radiotherapy post-surgery, GBM remains insensitive to existing treatment regimens, and patients usually have a poor prognosis. Recent studies indicate that the...

Nicotinamide Metabolism Face-off Between Macrophages and Fibroblasts Manipulates the Microenvironment in Gastric Cancer

Macroscopic and Microscopic Mechanisms of Nicotinamide Metabolism Antagonism: Manipulation of the Gastric Cancer Microenvironment Background Introduction Gastric cancer (GC) is a type of cancer characterized by a unique and heterogeneous tumor microenvironment (TME). Despite advances in immune checkpoint blockade (ICB) therapy for gastric cancer, n...
