Kaposi's sarcoma-associated herpesvirus (KSHV) encodes 3 genes that are homologous to cellular chemokines. vMIP-III, the product of open reading frame K4.1, is the most distantly related to human chemokines and has yet to be characterized. We have examined the interaction of vMIP-III with chemokine receptors, its expression in KS lesions, and its in ovo(More)
Human and simian immunodeficiency viruses (HIV and SIV) require a seven transmembrane chemokine (7TM) receptor in addition to CD4 for efficient entry into cells. CCR5 and CXCR4 act as major co-receptors for non-syncytium-inducing and syncytium-inducing strains respectively. We have examined the co-receptor requirement for HIV-1 infection of cells of(More)
Macrophage-derived chemokine (MDC) is a CC chemokine that recognizes the CCR4 receptor and is selective for T helper 2 (Th2) versus T helper 1 (Th1) cells. The present study was designed to investigate the effect of the prototypic Th2/Th1 cytokines, interleukin-4 (IL-4) and interferon-gamma (IFN-gamma), on the production of MDC by human monocytes. IL-4 and(More)
E2F is a cellular transcription factor that is regulated during the cell cycle through interactions with the product of the retinoblastoma susceptibility gene (RB1) and the pRb-like p107 and p130 proteins. Analysis of mutations within both adenovirus E1A and pRb, which affected their ability to regulate cellular proliferation and alter E2F activity,(More)
High throughput partial sequencing of randomly selected cDNA clones has proven to be a powerful tool for examining the relative abundance of mRNAs and for the identification of novel gene products. Because of the important role played by macrophages in immune and inflammatory responses, we sequenced over 3000 randomly selected cDNA clones from a human(More)
Human herpesvirus type 8 vMIP-II has one of the broadest ranges of chemokine receptor binding and therefore a multiplicity of biologic effects, both immunologic and antiviral. These properties make vMIP-II an attractive effector gene to be expressed from gene therapy vectors. The present studies were concerned with both therapeutic approaches: (1) an(More)
