Klebsiella pneumoniae-derived extracellular vesicles impair endothelial function by inhibiting SIRT1

Klebsiella pneumoniae-Derived Extracellular Vesicles Impair Endothelial Function by Inhibiting SIRT1 Academic Background Hypertension is a global health issue with a complex pathogenesis involving multiple factors. In recent years, the role of gut microbiota in hypertension has garnered significant attention. Studies have shown that dysbiosis of th...

Role of Sirtuins in Obesity and Osteoporosis: Molecular Mechanisms and Therapeutic Targets

The Role of Sirtuins in Obesity and Osteoporosis and Their Therapeutic Potential Academic Background Obesity and osteoporosis (OP) are increasingly severe public health issues worldwide. Obesity is not only closely related to metabolic diseases such as cardiovascular diseases and diabetes but also has a complex association with the occurrence of os...

Co-targeting of Glial Activation and Inflammation by tsRNA-Gln-I-0095 for Treating Retinal Ischemic Pathologies

Study on the Regulatory Mechanism of tsRNA-Gln-i-0095 in Retinal Ischemia-Reperfusion Injury Academic Background Retinal ischemia-reperfusion (I/R) injury is a critical pathological mechanism in various ocular diseases, including glaucoma, central retinal vein occlusion, and retinopathy of prematurity. I/R injury leads to the death of retinal gangl...

Regulation of Calcium Homeostasis in Endoplasmic Reticulum–Mitochondria Crosstalk: Implications for Skeletal Muscle Atrophy

The Critical Role of Calcium in Skeletal Muscle Function and Its Interaction with Mitochondria and the Endoplasmic Reticulum Academic Background Calcium ions (Ca²⁺) are crucial intracellular signaling molecules, particularly in the excitation-contraction coupling (ECC) of skeletal muscle. The contraction of skeletal muscle relies on the release and...

Poldip2 Mediates Brain Vascular Permeability by Regulating ROS-Mediated ZO-1 Phosphorylation and Localization at the Interendothelial Border

POLDIP2 Regulates Cerebral Vascular Permeability by Modulating ROS-Mediated ZO-1 Phosphorylation and Localization Background The blood-brain barrier (BBB) is a critical component of the central nervous system (CNS), composed of brain endothelial cells, astrocytes, pericytes, and neurons. Brain endothelial cells form a continuous physical barrier th...

N88S Seipin-related Seipinopathy: A Lipidopathy Associated with Loss of Iron Homeostasis

N88S Seipin-related Seipinopathy is a Lipidopathy Associated with Loss of Iron Homeostasis Academic Background Seipin is a protein encoded by the human BSCL2 gene and the yeast SEI1 gene, forming an endoplasmic reticulum (ER)-bound homo-oligomer. This oligomer plays a crucial role in targeting ER-lipid droplet (LD) contact sites, facilitating the d...

PRDX5 and PRDX6 Translocation and Oligomerization in Bull Sperm: A Response to Cryopreservation-Induced Oxidative Stress

PRDX5 and PRDX6 in Oxidative Stress Response During Cryopreservation of Bull Sperm Academic Background Cryopreservation is a critical step in animal breeding and assisted reproductive technologies, particularly in the preservation of bull sperm. However, oxidative stress generated during cryopreservation significantly reduces sperm quality, leading...

FOXC1-Mediated Serine Metabolism Reprogramming Enhances Colorectal Cancer Growth and 5-FU Resistance

FOXC1-Mediated Serine Metabolism Reprogramming Enhances Colorectal Cancer Growth and 5-FU Resistance Background Colorectal cancer (CRC) is the third most common cancer globally and the second leading cause of cancer-related deaths. Although surgical resection and adjuvant chemotherapy are the primary treatments for CRC, tumor development and chemot...

Staphylococcus aureus Vesicles Impair Cutaneous Wound Healing through p38 MAPK-MERTK Cleavage-Mediated Inhibition of Macrophage Efferocytosis

Staphylococcus Aureus Vesicles Impair Cutaneous Wound Healing Through p38 MAPK-MerTK Cleavage-Mediated Inhibition of Macrophage Efferocytosis Background Introduction Staphylococcus aureus (S. aureus) is one of the primary pathogens causing chronic wound infections, particularly in diabetic patients, with an infection rate as high as 65%. One of the...

Kindlin-3 but not Talin-1 Contributes to β2 Integrin Clustering

The Critical Role of Kindlin-3 in β2 Integrin Clustering Academic Background Neutrophils are the most abundant type of white blood cells in human blood, and their recruitment is essential for innate immunity and inflammatory responses. The initial and critical step in neutrophil recruitment is their adhesion to vascular endothelial cells, which dep...
