Ribosomes are organelles composed of ribosomal proteins (riboproteins) and ribonucleic acids (ribonucleoproteins). The word ribosome is made from taking â ribo â from ribonucleic acid and adding it to â soma â, the latin word for body. Ribosomes are bound by a membrane but they are not membranous.
Causes. In a majority of cases of membranous nephropathy, evidence of autoimmune activity can be found. Your body's immune system mistakes some of your own tissues as foreign and attacks them with autoantibodies. These autoantibodies can damage your kidney's filtering systems (glomeruli). Sometimes membranous nephropathy is brought on by other causes, notably: 1  Autoimmune disease, such as lupus erythematosus. 2  Infection with hepatitis B, hepatitis C or syphilis. 3  Certain medications, such as gold salts and nonsteroidal anti-inflammatory drugs.
