Disclosed are alphavirus-based expression vectors expressing env, gag, pro, and/or pol genes of HIV-1, their transcripts, and transformed host cells. The present invention describes the expression of the Gag, Env, Pol, and/or Pro Proteins using the above expression vectors, and HIV-like particles (HIVLPs) composed of the above recombinant proteins. The virus-like particles (VLPs) of the present invention, as the mature and infective particles, are very useful as an antigen for a diagnostic kit for HIV infection as well as for a vaccine composition for prevention of HIV infection.
