Beschreibung:
A specific inhibitor of the neuraminidase of the protozoan parasite Trypanosoma cruzi was isolated recently and named cruzin. It is now shown that cruzin is similar to high-density lipoprotein by amino acid homology, by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, by immunoblot analysis, and by isoelectric focusing. Cruzin purified by ion exchange chromatography and high-density lipoprotein isolated by density gradient ultracentrifugation inhibited Trypanosoma cruzi neuraminidase to the same extent. Cruzin or high-density lipoprotein restores to normal the decreased multiplication rate of Trypanosoma cruzi epimastigotes grown in a medium depleted of lipoproteins, suggesting that it may be important for survival of the parasite in nature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prioli, R P -- Ordovas, J M -- Rosenberg, I -- Schaefer, E J -- Pereira, M E -- AI 07380/AI/NIAID NIH HHS/ -- AI 18102/AI/NIAID NIH HHS/ -- HL 35243/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1987 Dec 4;238(4832):1417-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Geographic Medicine and Infectious Diseases, New England Medical Center Hospitals, Inc., Boston, MA 02111.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3120314" target="_blank"〉PubMed〈/a〉
