Summary
Membranous nephropathy (MN) involves chronic inflammation, potentially linked to conditions like thyroiditis. This inflammation may trigger antibodies against PLA2R, causing MN disease.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- Membranous nephropathy (MN) presents complex etiology and pathogenesis, challenging clinical management.
- The disease course is variable, with spontaneous remissions and relapses, complicated by antibody involvement and potential malignancy.
- Differentiating MN types is difficult due to current diagnostic limitations.
Purpose of the Study:
- To investigate potential correlations between comorbidities and the occurrence/course of membranous nephropathy.
- To develop a hypothetical pathogenetic model for MN based on clinical data and inflammation markers.
- To explore the role of chronic inflammation in PLA2R-expressing sites in MN development.
Main Methods:
- Analysis of data from 12 MN patients (2-10 year observation) including kidney biopsy, immunological, histopathological, and immunohistochemical tests.
- Histopathological and immunohistochemical examination of thyroid and gallbladder tissue in select MN patients.
- Evaluation of comorbidities in 102 MN patients to establish correlations.
Main Results:
- A connection was identified between chronic cholecystitis, thyroiditis, hepatitis, and the occurrence/course of MN.
- Chronic inflammation in PLA2R-expressing sites was linked to the formation of anti-PLA2R antibodies.
- These antibodies deposit in the subepithelial space, leading to the manifestation of MN.
Conclusions:
- Chronic inflammation in specific organs may predispose individuals to developing antibodies against PLA2R, initiating MN.
- Comorbidities such as chronic cholecystitis and thyroiditis appear to influence MN development and progression.
- The proposed pathogenetic model highlights inflammation-driven antibody formation as a key factor in MN etiology.

01:10Nephrons
1.9K
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...

174
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

9.2K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...
