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, ...

Alcaligenes faecalis Induces Intestinal T Helper 17 Cells by Promoting E3 Ubiquitin Ligase TRIM21-Mediated FBXW7 Degradation

1. Research Background Intestinal Th17 cells play a central role in maintaining mucosal immune homeostasis and defending against pathogen infections. Previous studies identified segmented filamentous bacteria (SFB) as key microbes inducing intestinal Th17 cells, but controversies exist regarding SFB colonization in adult intestines: 1. Clinical Par...

Multiscale Footprints Reveal the Organization of Cis-Regulatory Elements

Multiscale Footprints Reveal the Role of Cis-Regulatory Elements in Cell Differentiation and Aging Background Introduction The regulation of gene expression is a key mechanism in cell fate determination and disease development, and cis-regulatory elements (CREs) play a crucial role in this process. CREs dynamically regulate gene expression by bindi...

JAK2/mTOR Inhibition Fails to Prevent Acute GVHD Despite Reduced Th1/Th17 Cells: Final Phase 2 Trial Results

Inhibition of JAK2/mTOR Fails to Effectively Prevent Acute Graft-versus-Host Disease (GVHD): Limitations of Targeting Th1/Th17 Cells In recent years, the role of systemic immunosuppressive therapies in preventing acute graft-versus-host disease (aGVHD) following allogeneic hematopoietic cell transplantation (alloHCT) has come under scrutiny. Th1 (T...

Cycling Alpha Cells in Regenerative Drug-Treated Human Pancreatic Islets May Serve as Key Beta Cell Progenitors

Academic Background Diabetes is a global health issue affecting over 500 million people. Both type 1 diabetes (T1D) and type 2 diabetes (T2D) share the common feature of a significant reduction in the number of functional insulin-secreting beta cells. Therefore, restoring or increasing beta cell mass is considered a key strategy in diabetes treatme...
