title: Transcripts of the human herpesvirus 8 genome in skin lesions and peripheral blood mononuclear cells of a patient with classic Kaposi's sarcoma.
abstract: We report a 75-year-old Japanese woman with classic Kaposi's sarcoma. PCR amplified human herpesvirus 8 (HHV-8) DNA sequences from her skin lesions and peripheral blood mononuclear cells (PBMC), but not her plasma, saliva or urine. An antibody test against HHV-8 lytic antigens was positive. Immunohistochemical staining detected latent antigen. There was no evidence of HHV-8 infection in her husband, sister or daughter. Genes coding for HHV-8-encoded viral interleukin-6, viral macrophage inflammatory protein I, viral G protein-coupled receptor, viral cyclin D and viral Bcl-2 were expressed to the same degree in both her skin lesion and PBMC. Latency-associated T0.7 mRNA and HHV-8-encoded viral tegument protein genes were expressed in her PBMC at levels lower than in the skin lesions. Based on the gene expression profile, we concluded that lytic HHV-8 infection was present in her skin lesions and PBMC.
