What is the outer layer of the fenestrated endothelium?
A fenestrated endothelium forms the inner glomerular layer, followed by a layer composed of various extracellular proteins forming a meshwork called the glomerular basement membrane (GBM). The outer layer has visceral epithelial cells or podocytes, along with mesangial cells. The intricate arrangement provides the basis of the continuous plasma volume filtration that occurs at the glomerular level.
Why does edema occur when the glomerular filtration rate is decreased?
As the glomerular filtration rate (GFR) is decreased, symptoms like edema and hypertension occur, majorly due to the subsequent salt and water retention caused by the activation of the renin-angiotensin-aldosterone system.

What are the symptoms of glomerulonephritis?
When rapidly progressive glomerulonephritis develops, weakness, fatigue, and fever are the most frequent early symptoms. Loss of appetite, nausea, vomiting, abdominal pain, and joint pain are also common. About 50% of people have a flu-like illness in the month before kidney failure develops.
How do you know if you have glomerulonephritis?
If symptoms do occur, the first to appear are tissue swelling (edema) due to fluid retention, low urine volume, and production of urine that is dark because it contains blood. Edema may first appear as puffiness of the face and eyelids but later is prominent in the legs. Blood pressure increases (see The Body's Control of Blood Pressure) as kidney function becomes impaired. Some people become drowsy or confused. In older people, nonspecific symptoms, such as nausea and a general feeling of illness (malaise), are more common.

The most common cause in children is minimal change glomerulonephritis. In white adults, nephrotic syndrome is most frequently due to membranous nephropathy whereas in populations of African ancestry the most common cause of nephrotic syndrome is focal segmental glomerulosclerosis.
What mutations in podocytes are associated with nephrotic syndrome?
Mutations in several podocyte proteins have been identified in families with inherited nephrotic syndrome; a plasma factor may alter glomerular permeability, especially in patients with the steroid-resistant nephrotic syndrome and lastly altered T-lymphocyte polarized immune responses, in that the T-cells could result in the production of a permeability factor. Increased plasma levels of IgE, IgG4, and association with atopy suggest type II cytokine bias in patients with MCNS.In vitro studies suggest that podocytes express receptors for IL-4 and IL-13, the activation of these receptors might disrupt glomerular permeability resulting in proteinuria. No particular cytokine triggers the nephrotic syndrome.
What is the nephrotic range of proteinuria?
Urine tests:Nephrotic-range proteinuria will be apparent by 3+ or 4+ readings on the dipstick, or by semiquantitative testing by sulfosalicylic acid. A 3+ reading represents 300 mg/dL of urinary protein or more, which correlates with a daily loss of 3 g or more and thus is in the nephrotic range. Urine samples over 24 hours (for an accurate measure), proteinuria (3 g protein )is diagnostic. [9][10][11]
