COMPOSITIONS AND METHODS OF USING CAPSID PROTEIN FROM FLAVIVIRUSES AND PESTIVIRUSES

摘要

This invention provides methods of inducing cell death with Flavivirus or Pestivirus capsid protein, such as West Nile virus (WNV) capsid protein, and functional fragments thereof. The invention also provides methods of treating patients suffering from diseases characterized by hyperproliferating cells by administering pharmaceutical compositions comprising WNV or other virus including Flavivirus or Pestivirus capsid or other protein or a nucleic acid molecule encoding the same. Methods of identifying compounds which have anti-viral and/or anti-WNV and/or anti-Flavivirus and/or anti-Pestivirus capsid or other protein activity are disclosed. The invention also provides vaccine compositions comprising capsid or other proteins, or fragments thereof, or nucleic acids encoding same, from WNV or other virus including Flavivirus or Pestivirus and a pharmaceutically acceptable carrier. The invention also provides diagnostic methods and kits for identifying individuals exposed to WNV or other viruses including Flavivirus or Pestivirus.
