Summary
Annexin A2, a multifunctional protein, plays a key role in kidney diseases by mediating inflammation and podocyte damage. Understanding its aberrant expression is crucial for disease progression insights.
Area of Science:
- Molecular Biology
- Cell Biology
- Nephrology
Background:
- Annexin A2 is a calcium and phospholipid-binding protein with diverse cellular functions.
- It is involved in exocytosis, endocytosis, migration, proliferation, and blood coagulation.
- Annexin A2 acts as a receptor for plasminogen and tissue plasminogen activator, influencing fibrinolysis and matrix degradation.
Purpose of the Study:
- To review the current understanding of Annexin A2's role in kidney diseases.
- To highlight Annexin A2's implication in the pathogenesis and progression of renal pathologies.
Main Methods:
- Literature review of studies on Annexin A2 and kidney diseases.
- Analysis of Annexin A2's molecular mechanisms in renal inflammation and damage.
Main Results:
- Aberrant Annexin A2 expression is observed in numerous kidney diseases.
- Annexin A2 mediates NF-kB-dependent kidney inflammation via integrin CD11b.
- It triggers macrophage phenotypic changes and modulates podocyte cytoskeleton, leading to proteinuria.
Conclusions:
- Annexin A2 is significantly implicated in the pathogenesis and progression of various kidney diseases.
- Its aberrant expression contributes to renal inflammation and podocyte dysfunction.
- Further research into Annexin A2's role may offer therapeutic targets for kidney diseases.

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
