Manifestations of Genomic-Level Intratumoral Tumor Heterogeneity in Multi-Region Patient-Derived Xenograft Models of Non-Small Cell Lung Cancer Academic Background and Research Motivation Patient-Derived Xenograft (PDX) models are widely used in cancer research. PDX models are established by transplanting human tumors into immunodeficient mice. The...
Orthogonal Proteogenomic Analysis Identifies Druggable PA2G4-MYC Axis in 3q26 AML Acute myeloid leukemia (AML) is a highly heterogeneous and aggressive malignancy. In particular, the 3q26 chromosomal abnormality subtype of AML has a complex pathogenic mechanism and lacks effective targeted therapies. To address this challenge, Matteo Marchesini and...
Acetate Reprograms Tumor Metabolism and Promotes Immune Evasion and PD-L1 Expression by Upregulating c-myc Introduction Reprogramming of tumor metabolism is of great significance in cancer research, and acetate plays a crucial role in this process. In tumor cells, acetate is an important precursor of acetyl-CoA, which is used for energy production,...
Scientific Paper Report Discoveries in the field of science often have significant implications for understanding natural phenomena and improving practical applications. Recently, a research paper published in Science Immunology titled “Serine enrichment in tumors promotes regulatory T cell accumulation through sphinganine-mediated regulation of c-...
Heart Failure Promotes Multimorbidity through Innate Immune Memory Research Background Despite significant medical advances, the mortality rate of heart failure (HF) remains high, necessitating new therapeutic targets. HF patients often experience acute decompensation and develop comorbidities such as chronic kidney disease and frailty syndrome. Th...
Interaction and Attenuation of Tumor-Specific CD8+ T Cell Responses by LRIG1 and VISTA Academic Background In recent years, the importance of immune checkpoint inhibitors (ICIs) such as Programmed Cell Death Protein 1 (PD-1) and Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4) has received increasing attention. These inhibitors significantly improve the s...
TREM2 Deficiency Reprograms Gut Macrophages and Microbiota to Enhance Anti-PD-1 Tumor Immunotherapy Background Immune checkpoint inhibitors (CPIs), such as drugs that block programmed cell death protein-1 (PD-1), programmed death-ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated protein-4 (CTLA-4), have been successfully used to activate anti...
The Tumor Lactate-SREBP2 Signaling Pathway Drives Tolerogenic Dendritic Cell Maturation and Promotes Cancer Progression In recent years, the critical role of dendritic cells (DCs) in antitumor immunity has been widely recognized. However, many cancers cause DC dysfunction through mechanisms that are not fully understood. In a newly published study ...
Research Progress in Cancer Immunology: Tumor-derived Antigen Signals Induce CD8+ T-cell Exhaustion Localized to the Tumor Site Research Background and Purpose In recent years, immunotherapy has shown great potential in cancer treatment. However, tracking the behavior of immune cells after receiving antigen signals remains a challenge. Within tumor...
A Panoramic View of Whole Genome Repetitive Sequences in Cancer and Circulating Free DNA Research Background and Significance Throughout the development of cancer and other diseases, genetic changes in repetitive sequences within the genome are a significant characteristic. However, standard sequencing methods struggle to effectively characterize t...
