Selective Advantage of Clonal Hematopoietic Mutant Stem Cells in Aging and Inflammatory Responses Background and Research Motivation Clonal Hematopoiesis (CH) is an aging-related phenomenon in the hematopoietic system, where hematopoietic stem cells (HSCs) acquire specific somatic mutations and undergo expansion, causing a particular mutated cell l...
Epitope Prime Editing Shields Hematopoietic Cells from CD123 Immunotherapy: A Novel Therapeutic Strategy for Acute Myeloid Leukemia Research Background and Problem Statement Acute Myeloid Leukemia (AML) is a malignant blood disease characterized by the abnormal differentiation of myeloid hematopoietic stem and progenitor cells (HSPCs). Its incidenc...
Metabolic and Epigenetic States of HSC-Derived Macrophages in Autoimmune Diseases and Their Driving Mechanism of Trained Immunity Research Background In the context of autoimmune diseases (AD), studies have shown that prolonged activation of the immune system and inflammatory responses affect not only mature immune cells but also have profound effe...
Research Background The maintenance and repair of the hematopoietic system are crucial for the continuation of life and health in an organism. As the foundation of the hematopoietic system, the stability of hematopoietic stem cells (HSCs) is particularly important. The maintenance of the HSC pool relies on intrinsic and extrinsic factors, among whi...
Research Background and Objective As individuals age, hematopoietic stem cells (HSCs) progressively accumulate in the bone marrow, exhibiting metabolic resilience under various stress conditions. This metabolic resilience provides an aging advantage for HSCs, enabling them to maintain cell viability even under low metabolic conditions. Although agi...
Nynrin Protects Hematopoietic Stem Cell Function by Inhibiting Mitochondrial Permeability Transition Pore Opening Background and Research Motivation Hematopoietic stem cells (HSCs) are core cells that maintain the function of the hematopoietic system, showing unique adaptability to stress environments such as radiation damage. However, while conven...
MGA Deletion Promotes Richter’s Transformation by Regulating Mitochondrial Oxidative Phosphorylation This article mainly focuses on the transformation of chronic lymphocytic leukemia (CLL) into aggressive lymphoma, known as Richter’s Transformation (RT), exploring the function and molecular mechanism of MGA (MAX Gene Associated). MGA is a functiona...
Research Background Severe alcoholic hepatitis (ALD) is a fatal form of alcohol-associated liver disease (AALD). The course of ALD is usually accompanied by neutrophil infiltration in the liver, which significantly affects the severity of the condition. However, the specific effects of alcohol on neutrophil function remain unclear. Based on this, i...
Comparison of SaCas9 and SpCas9 in High-Fidelity and Different Gene Editing Outcomes Research Background CRISPR systems based on Cas9 protein have become powerful tools for genome editing, widely used in basic research and clinical gene therapy. Currently, the most commonly used Cas9 variants are SpCas9 from Streptococcus pyogenes and SaCas9 from S...
Comprehensive Characterization and Transcriptome Analysis of Terminal Erythropoiesis in Human Fetal Liver Background and Research Question Erythropoiesis is the process of red blood cell production. Initially, “primitive” erythropoiesis occurs in the yolk sac, gradually replaced by “terminal” erythropoiesis in the fetal liver (FL) and postnatal bon...
