Selective Advantage of Mutant Stem Cells in Human Clonal Hematopoiesis Associated with Attenuated Response to Inflammation and Aging

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...

Increased Cholesterol Synthesis Drives Neurotoxicity in Patient Stem Cell-Derived Model of Multiple Sclerosis

Lipid Metabolism Mechanisms in Neurodegenerative Diseases: A New Study on Multiple Sclerosis Multiple Sclerosis (MS) is a common inflammatory autoimmune demyelinating disease of the central nervous system (CNS). As the disease progresses, patients gradually experience neurological damage and disability. Although there have been advances in the trea...

Epitope Editing Protects Hematopoietic Cells from CD123 Immunotherapy for Acute Myeloid Leukemia

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...

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...

Human Vascularized Macrophage-Islet Organoids to Model Immune-Mediated Pancreatic B Cell Pyroptosis upon Viral Infection

Background Since the outbreak of the COVID-19 pandemic, SARS-CoV-2 infection has not only affected the respiratory system but has also been closely related to metabolic diseases such as diabetes. Clinical observations have found occurrences of new-onset diabetes and worsening of existing diabetes among COVID-19 patients, particularly with an increa...

The Landscape of Drug Sensitivity and Resistance in Sarcoma

Background Introduction This study explores the landscape of individual drug sensitivity and resistance in sarcoma patients. Sarcomas are a diverse group of tumors originating from mesenchymal tissue, including types such as osteosarcoma and soft tissue sarcoma, mostly affecting young people. Although the annual incidence of sarcomas is relatively ...

Inflammation-Induced Epigenetic Imprinting Regulates Intestinal Stem Cells

Inflammation-Induced Epigenetic Imprinting and Intestinal Stem Cell Regulation In recent years, the scientific community has shown immense interest in the “memory” capabilities of non-immune cells, particularly the phenomenon where specific stem cells in adult tissues develop memory after undergoing inflammation, influencing their functionality. Ho...

Embryonic Macrophages Support Endocrine Commitment During Human Pancreatic Differentiation

The Role of Embryonic Macrophages in Human Pancreatic Development Background and Research Motivation Pancreatic development involves complex interactions between various cell types. In recent years, the influence of multiple cells within the pancreatic microenvironment has gained attention; however, the role of immune cells in pancreatic organogene...

Sustained Amphiregulin Expression in Intermediate Alveolar Stem Cells Drives Progressive Fibrosis

Persistent Expression of Amphiregulin (AREG) in Intermediate Alveolar Stem Cells Drives Progressive Pulmonary Fibrosis Background Fibrotic diseases are a leading cause of up to 45% of deaths in developed countries. Pulmonary fibrosis is a disease characterized by alveolar structure damage and impaired gas exchange, with Idiopathic Pulmonary Fibrosi...

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...
