The T-cell receptor (TCR) complex is a protein receptor composed of TCRα, β, and ζ chains. B cells in LN patients have more MicroRNAs (miRNAs) which modulate gene expression [2]. Since anti-DNA antibodies are present in the circulation and in diseased glomeruli of patients with lupus nephritis, these antibodies have been assigned a pivotal role in the initiation of lupus nephritis. Autoantibodies direct themselves against nuclear elements. Epub 2014 Jan 7. The Pathogenesis and Therapeutic Implications of Tubulointerstitial Inflammation in Human Lupus Nephritis. HHS The pathophysiology of systemic lupus erythematosus involves the immune system.

Here we provide an update on the pathophysiology of lupus and its related kidney disease, consider areas of controversy in disease management, and discuss the unmet needs of lupus nephritis and how to address these needs. Although lupus nephritis may return in a transplanted kidney, it rarely leads to end-stage kidney disease. Other factors such as genetic factors, hormonal abnormalities, and environmental factors also play a role. Rheumatol Int. However, until now no consensus has been reached whether only a subpopulation of these antibodies is really nephritogenic. Lupus nephritis is glomerulonephritis caused by systemic lupus erythematosus (SLE). 2002 Aug;130 Suppl 3:38-41. This interactions produce multiple inflammatory mediators which lead to LN.
