Scientists have discovered that a lipid known to protect the heart from inflammation and to cause skin allergic reactions also reduces inflammation of the kidneys. The discovery could help devise new ways of treating inflammatory kidney diseases.

The lipid, called sphingosylphosphorylcholine (SPC), has been shown to cause an increase in urine production in the kidneys and an abnormal accumulation of salt in the urine. But how SPC works in the kidneys is not completely understood.

Andrea Huwiler and colleagues examined the various proteins activated by SPC in kidney cells and showed for the first time that SPC triggers proteins known to reduce inflammation. Although more details will be needed to understand how these proteins and how SPC may interact with other anti-inflammatory proteins - such as transforming growth factor beta - SPC may be useful in the treatment of chronic inflammatory and fibrotic diseases of the kidneys, the scientists concluded.

The American Society for Biochemistry and Molecular Biology is a nonprofit scientific and educational organization with over 11,900 members in the United States and internationally. Most members teach and conduct research at colleges and universities. Others conduct research in various government laboratories, nonprofit research institutions and industry. The Society's student members attend undergraduate or graduate institutions.

Founded in 1906, the Society is based in Bethesda, Maryland, on the campus of the Federation of American Societies for Experimental Biology. The Society's purpose is to advance the science of biochemistry and molecular biology through publication of the Journal of Biological Chemistry, the Journal of Lipid Research, and Molecular and Cellular Proteomics, organization of scientific meetings, advocacy for funding of basic research and education, support of science education at all levels, and promoting the diversity of individuals entering the scientific work force.
