A method of inducing cytostasis in a population of HIV-infected cells is
disclosed which comprises applying to a population of HIV-infected cells
a cytostatically effective amount of an inhibitor comprising an isolated
peptide having the amino acid sequence FCRFLLCPSRTSD or
SQCEQEGGRCRFLLCPSRTSNIGKLGCEPLWKC CKRWGG, or a conservative variant
thereof, whereby cell growth in at least a portion of the HIV-infected
cells is arrested, rendering the growth-arrested cells non-HIV producing.
The peptide may be conjugated with an agent that is capable of
selectively targeting HIV-infected cells.
