ALPHAVIRUS EXPRESSION VECTOR

摘要

The present invention is directed to alphavirus expression vectors comprising at least part of an alphavirus genome and hetetologous RNA inserted downstream of an alphavirus base sequence having translation enhancing activity. Such vectors can be used to achieve enhanced levels of expression of DNA or cDNA coding for a desired product and being complementary to said heterologous RNA after introduction of said vector in eukaryotic cells in cell culture or in a living body. The expression product may have therapeutical or prophylactic activity.
