B-cell alloantigen associated with chronic mesangiocapillary glomerulonephritis
Lancet (London, England)
|March 12, 1977
Summary
Researchers identified a B-cell antigen linked to chronic mesangiocapillary glomerulonephritis (M.C.G.). This discovery suggests a potential diagnostic marker for M.C.G., an immune-mediated kidney disease.
Area of Science:
- Nephrology
- Immunology
- Genetics
Background:
- Chronic mesangiocapillary glomerulonephritis (M.C.G.) is an immune-mediated kidney disease.
- The genetic and immunological factors contributing to M.C.G. pathogenesis are not fully understood.
Purpose of the Study:
- To investigate potential B-lymphocyte alloantigen associations in patients with M.C.G.
- To identify specific B-cell determinants linked to the development of M.C.G.
Main Methods:
- Analysis of B-lymphocyte alloantigens in thirteen M.C.G. patients.
- Utilized antisera from multiparous mothers of M.C.G. probands for B-cell typing.
- Immunofluorescent microscopy was used for diagnosis.
Main Results:
- A specific B-cell antigen, identified by the M.C.G.3 antiserum, was found in 77% of M.C.G. patients versus 17% of controls.
- Individuals with the M.C.G.3 antigen had a 16.6 times higher risk of developing M.C.G.
Conclusions:
- This study demonstrates the first association between a specific B-lymphocyte determinant and immune-mediated glomerulonephritis.
- The identified M.C.G.3 antigen may serve as a potential diagnostic marker for M.C.G.
