A Distinct Metabolic and Epigenetic State Drives Trained Immunity in HSC-Derived Macrophages from Autoimmune Mice

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...

Mitochondrial Serine Catabolism Maintains Hematopoietic Stem Cell Pool in Homeostasis and Injury

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...

Role of SDHAF1 in Aging Hematopoietic Stem Cells: Enhancing Metabolic Resilience through Mitochondrial ATP Production

Role of SDHAF1 in Aging Hematopoietic Stem Cells: Enhancing Metabolic Resilience through Mitochondrial ATP Production

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...

A New Protein Regulating Mitochondrial Function for Maintaining Hematopoietic Stem Cell Viability: The Role of Nynrin

A New Protein Regulating Mitochondrial Function for Maintaining Hematopoietic Stem Cell Viability: The Role of Nynrin

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 Leads to Richter’s Transformation by Modulating Mitochondrial OXPHOS

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...

In Vivo Bruton's Tyrosine Kinase Inhibition Attenuates Alcohol-Associated Liver Disease by Regulating CD84-Mediated Granulopoiesis

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...
