Large-scale plasma proteomic profiling unveils diagnostic biomarkers and pathways for Alzheimer's disease

1. Research Background and Academic Significance Alzheimer’s Disease (AD) is the most common form of dementia worldwide, accounting for about 60–80% of all dementia cases. The primary affected population is individuals over 65 years old, with characteristic pathological features including the deposition of amyloid-β plaques, neurofibrillary tangles...

Mitochondria-Enriched Hematopoietic Stem Cells Exhibit Elevated Self-Renewal Capabilities Within the Context of Aged Bone Marrow

Mitochondria-Enriched Hematopoietic Stem Cells Reveal Enhanced Self-Renewal Activity in Aged Bone Marrow: In-Depth Analysis of the Latest Study in Nature Aging I. Academic Background and Research Significance Hematopoietic stem cells (HSCs) are the essential foundation underlying life-long production of blood and immune cells. However, with aging, ...

Retrotransposon-Derived Capsid Genes PNMA1 and PNMA4 Maintain Reproductive Capacity

Mechanistic Study on How Retrotransposon-derived Capsid Genes PNMA1 and PNMA4 Maintain Reproductive Capacity — A New Research Review from Nature Aging I. Research Background and Scientific Significance Nearly half of the DNA in the human and mammalian genome is made up of retrotransposons, sequences that originally existed as “parasitic molecules” ...

Activation of AMPK by GLP-1R Agonists Mitigates Alzheimer-Related Phenotypes in Transgenic Mice

I. Research Background and Scientific Question Alzheimer’s disease (AD) is the most common neurodegenerative disease worldwide, with pathological features mainly including neuronal loss, neurofibrillary tangles, and senile plaques (mainly formed by amyloid-β [Aβ] deposition). According to statistics, the number of AD patients continues to rise each...

Large-Scale Network Analysis of the Cerebrospinal Fluid Proteome Reveals Molecular Signatures of Frontotemporal Lobar Degeneration

Analysis of Large-Scale Network Study of the CSF Proteome in FTLD — Unlocking Molecular Signatures of Neurodegenerative Diseases I. Academic Background and Motivation Frontotemporal Lobar Degeneration (FTLD) is one of the most common causes of early-onset dementia (under age 65), triggering a range of progressive behavioral, language, and even moto...

Breakthrough Study on Consistent Self-Organized Formation of Hyaline Cartilage in hiPSC-Derived Multi-Tissue Organoids I. Academic Background 1.1 The Medical Challenge of Cartilage Injury Cartilage is an important connective tissue within human joints, with hyaline cartilage especially covering joint surfaces and playing a core role in smooth movem...

Exosomes Derived from Exercise-Trained Mice Bone Marrow Mesenchymal Stem Cells Improve Wound Healing by Inhibiting Macrophage M1 Polarization

I. Academic Background and Research Significance Wound healing is a highly complex physiological process that plays a crucial role in tissue regeneration, repair, and immune regulation. However, poor healing of chronic wounds is clinically widespread, severely impacting patients’ quality of life and increasing medical and socioeconomic burdens. The...

Contribution of Cytokeratin 19-Expressing Cells towards Islet Regeneration Induced by Multipotent Stromal Cell Secreted Proteins

Background Introduction Diabetes, especially type 1 diabetes (T1D), is a chronic autoimmune disease characterized by the persistent destruction of pancreatic β cells by the immune system, resulting in the loss of the ability to regulate blood glucose. Patients with type 1 diabetes typically require lifelong insulin injections; however, long-term in...

Neural Stem Cell-Derived Extracellular Vesicles Alleviate Inflammatory Responses in a Mouse Model of Atopic Dermatitis

I. Academic Background and Research Motivation Atopic Dermatitis (AD) is a common chronic inflammatory skin disease characterized by eczematous lesions, intense itching, and impairment of skin barrier function. Its pathogenesis is highly complex, involving genetic susceptibility, epidermal barrier dysfunction, immune dysregulation, and environmenta...
