Advances in the Renin-Angiotensin-Aldosterone System: Relevance to Diabetic Nephropathy

The Scientific World Journal, 2008
Hypertension is now recognized as a key contributory factor to the development and progression of kidney disease in both type 1 and type 2 diabetes. The renin angiotensin system (RAS) and its effector molecule angiotensin II, in particular, have a range ...

Angiotensin II type 2 receptor antagonist reduces bleomycin-induced pulmonary fibrosis in mice

Respiratory Research, 2008
Background The role of angiotensin II type 2 receptor (AT2) in pulmonary fibrosis is unknown. To evaluate the influence of angiotensin II type 1 receptor (AT1) and AT2 antagonists in a mouse model of bleomycin (BLM)-induced pulmonary fibrosis. Methods We

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

Angiotensin II Type 2 Receptor Gene Transfer Downregulates Angiotensin II Type 1a Receptor in Vascular Smooth Muscle Cells [PDF]

Hypertension, 2002
Two distinct subtypes of angiotensin (Ang) II receptors, type 1 (AT 1 ) and type 2 (AT 2 ), have been identified. Vascular smooth muscle cells (VSMCs) usually express AT 1 receptor. To elucidate the direct effects of the AT 2 receptor on the AT

Extracellular Vesicles Modulation by an Adiponectin Receptor Agonist Provides Cardioprotection for Myocardial Ischemic Injury

Advanced Healthcare Materials, EarlyView.
This study demonstrates that ALY688, a drug mimicking the heart‐protective hormone adiponectin, reduces myocardial ischemia injury. ALY688 increases the production of extracellular vesicles, which carry protective cargo including adiponectin itself.

The angiotensin II type 2 receptor and the gastrointestinal tract

Journal of the Renin-Angiotensin-Aldosterone System, 2009
The renin-angiotensin system (RAS) is well known for its vital involvement in body fluid homeostasis and circulation. However, very little research has been devoted to the impact of this regulatory system on the gastrointestinal (GI) system.

Viral Infection‐Inspired Autonomous Detection of Fusion‐Competent Viruses for Screening and Environmental Surveillance

Advanced Materials, EarlyView.
Inspired by viral entry mechanisms, the FUSION assay enables autonomous detection of respiratory viruses via membrane fusion–triggered CRISPR‐Cas13a activation. VEACON selectively fuses with fusion‐competent viruses, triggering fluorescence within confined vesicles.

GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

Advanced Science, EarlyView.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

Cardiomyocyte autophagy is regulated by angiotensin II type 1 and type 2 receptors [PDF]

Autophagy, 2009
Autophagic activity increases in the heart in response to a variety of stresses including hypertension, ischemia and neonatal starvation. Constitutive autophagy plays an important role in the maintenance of cellular homeostasis in the heart, whereas unrestrained autophagic activity accentuates the maladaptive cardiac remodeling response to stress (e.g.,
