Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [1] but not all diseases necessarily have an inflammatory component.
Renal corpuscle showing glomerulus and glomerular capillaries Figure 2: (a) Diagram of the juxtaglomerular apparatus: it has specialized cells working as a unit which monitor the sodiujuxtaglomerular apparatus: it has three types of specm content of the fluid in the distal convoluted tubule (not labelled - it is the tubule on the left) and adjust the glomerular filtration rate and the rate of ...
Acute proliferative glomerulonephritis is a disorder of the small blood vessels of the kidney.It is a common complication of bacterial infections, typically skin infection by Streptococcus bacteria types 12, 4 and 1 but also after streptococcal pharyngitis, for which it is also known as postinfectious glomerulonephritis (PIGN) or poststreptococcal glomerulonephritis (PSGN).

Mesangial proliferative glomerulonephritis (MesPGN) is a morphological pattern characterized by a numerical increase in mesangial cells and expansion of the extracellular matrix within the mesangium of the glomerulus. [1] The increase in the number of mesangial cells can be diffuse or local and immunoglobulin and/or complement deposition can ...
These immune deposits recruit inflammatory cells to that area which release oxidants and proteases that damage the capillary wall. In addition to all this, that inflammation triggers the thickening of the basement membrane, which also triggers the mesangial cells of the glomerulus start to proliferate or divide and reach through the thick ...
IgA nephropathy (IgAN), also known as Berger's disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy) and the immune system; specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney.
Rep. Nancy Mace unveiled legislation Thursday aimed at protecting women and children from registered sex offenders in emergency shelters during the fallout from natural disasters.
More specifically, different diseases (many of which are mentioned above in the Causes section) affect different segments of the glomerulus and cause disease-specific segments of the glomerulus to become inflamed. Most often, it is dependent on what part of the glomerulus is damaged by antibody-antigen complex (immune complex) deposition. [9]
