Insights

The receptor for advanced glycation end products (RAGE) is a cell-surface protein involved in inflammation and cellular dysfunction. This study highlights RAGE's critical role in diseases like diabetes, neurodegeneration, and atherosclerosis.

Area of Science:

  • Immunology
  • Cell Biology
  • Molecular Medicine

Background:

  • The receptor for advanced glycation end products (RAGE) is a cell-surface protein belonging to the immunoglobulin superfamily.
  • RAGE is expressed on various cell types, including immune cells and vascular cells.
  • RAGE binds multiple ligands, including advanced glycation end products (AGEs) and amphoterin.

Purpose of the Study:

  • To present the pivotal role of RAGE in the progression of various diseases.
  • To elucidate the signaling pathways initiated by RAGE engagement.
  • To highlight RAGE's contribution to cellular dysfunction and tissue damage.

Main Methods:

  • Review of existing literature on RAGE function and its involvement in disease.
  • Analysis of RAGE signaling pathways, including NF-kappaB activation.
  • Correlation of RAGE expression and activity with disease pathogenesis.

Main Results:

  • RAGE engagement triggers intracellular signaling, leading to NF-kappaB activation.
  • Sustained RAGE signaling results in cellular dysfunction and tissue destruction.
  • RAGE plays a critical role in the progression of diabetes, inflammation, neurodegeneration, tumors, vascular injury, atherosclerosis, and septic shock.

Conclusions:

  • RAGE is a key mediator in the pathogenesis of numerous inflammatory and degenerative diseases.
  • Targeting RAGE may offer therapeutic strategies for a wide range of conditions.
  • Understanding RAGE's multifaceted roles is crucial for developing effective disease interventions.

Diabetic Neuropathy

DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
Proteoglycans01:05

Proteoglycans

Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

G Protein-coupled Receptors

G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
