RESUMO
A cDNA coding for human interleukin 2 (IL-2) was inserted into the genome of Autographa californica nuclear polyhedrosis virus adjacent to the polyhedrin promoter. Cells infected with recombinant virus produced high levels of Mr 15,500 IL-2 polypeptide, the majority of which was secreted into the culture medium during infection. The recombinant IL-2 was able to stimulate the growth of an IL-2-dependent cell line. The N-terminal amino acid sequence of the insect-derived IL-2 was identical to that of natural IL-2. Thus, a mammalian signal peptide was recognized and properly removed in insect cells.
