Abstract
A virion expression system for a desired protein packaged in an envelope derived from a retrovirus useful in administering proteins which cross cell membranes in order to serve their function. Preferred virions are those that carry an RNA sequence that encodes cytokines or lymphokines, and includes IL-2, multiple drug resistance protein, and TNF.
