1. Luxo e vinho : uma relação refletida em anúncios da revista veja uma relação refletida em anúncios da revista Veja
O principal objetivo desse estudo é apontar como anúncios publicitários refletem diferentes possibilidades de construções do luxo no segmento vinícola. A metodologia utilizada foi análise de conteúdo, aliada à revisão documental de revistas. O vinho é um produto que carrega consigo a competência da distinção social, característica que é a pri

2. CD4 Promoter Transactivation by Human Herpesvirus 6
The observation that human herpesvirus 6 (HHV-6) can induce CD4 gene transcription and expression in CD4− cells was reported several years ago (P. Lusso, A. De Maria, M. Malnati, F. Lori, S. E. DeRocco, M. Baseler, and R. C. Gallo, Nature 349:533–535, 1991) and subsequently confirmed (P. Lusso, M. S. Malnati, A. Garzino-Demo, R. W. Crowley, E. O. Long, a

3. CD4-independent infection by human immunodeficiency virus type 1 after phenotypic mixing with human T-cell leukemia viruses.
Although human immunodeficiency virus (HIV) is the causative agent of the acquired immunodeficiency syndrome and related disorders, it has been suggested that viral cofactors may accelerate the progression of the disease. We present evidence that human T lymphoid cells productively coinfected by HIV type 1 (HIV-1) and human T-cell leukemia virus type I (HTLV

4. In vitro susceptibility of T lymphocytes from chimpanzees (Pan troglodytes) to human herpesvirus 6 (HHV-6): a potential animal model to study the interaction between HHV-6 and human immunodeficiency virus type 1 in vivo.
The in vitro susceptibility of several nonhuman primate species to human herpesvirus 6 (HHV-6) was investigated. Only peripheral blood mononuclear cells from chimpanzees (Pan troglodytes) were found permissive to productive infection by HHV-6, indicating that the host range of HHV-6, albeit limited, may not be restricted to Homo sapiens. However, natural HHV

5. CD4 is a critical component of the receptor for human herpesvirus 7: interference with human immunodeficiency virus.
In this study, we demonstrate that the glycoprotein CD4, a member of the immunoglobulin superfamily, is a critical component of the receptor for human herpesvirus 7 (HHV-7), a recently discovered T-lymphotropic human herpesvirus. A selective and progressive downregulation of the surface membrane expression of CD4 was observed in human CD4+ T cells in the cou

6. Growth of macrophage-tropic and primary human immunodeficiency virus type 1 (HIV-1) isolates in a unique CD4+ T-cell clone (PM1): failure to downregulate CD4 and to interfere with cell-line-tropic HIV-1.
Human immunodeficiency virus type 1 (HIV-1) isolates derived directly from clinical samples are usually unable to grow in cytokine-independent continuous cell lines, thus hindering the study of their biological features and their sensitivity to humoral and cellular protective immunity. To overcome these limitations, we have derived from the Hut78 T-cell line
