| Research Abstract |
This studies have attempted Human Immunodeficiency Virus (HIV) infection in four CD4^+ or CD8^+ T-cell lines derived from HTLV-1 associated myelopathy virus (HAM) patients.
Not only CD4^+ cell line but also CD8^+ cell line could be infected with HIV and CD4^+ cell line showed a higher susceptibility than CD8^+ cell line on HIV infection.
HIV antigen in early stage after HIV incoulation was detected by using enzymed linked immunoabsorbent assay (ELISA) rather than indirect Immunofluorescence Assay (IFA).
HTLV-1 producing CD4^+ and CD8^+ cell lines became to express two viral antigens (HTLV-1 and HIV) after HIV inoculation.
The results indicated that CD4^-CD8^+ T-cell line from patient with HAM can be infected with HIV. So that, we have found that other epitopes except for CD4 antigen may be associated with HIV infection.
