| absence of kaposi's sarcoma-associated herpesvirus-like dna sequences in malignant vascular tumors of the serous membranes. | reports connect kaposi's sarcoma-associated herpesvirus (kshv) with various types of kaposi's sarcoma (ks) and body-cavity-based lymphomas (primary effusion lymphomas). kshv dna sequences have also been detected in a few non-ks malignant vascular tumors. to determine whether kshv is associated with malignant vascular tumors involving the body cavities, 11 primary vascular tumors of the serous membranes (4 angiosarcomas, 7 hemangioendotheliomas) were tested for kshv sequences by polymerase chain ... | 1996 | 8972473 |
| selective switch between latency and lytic replication of kaposi's sarcoma herpesvirus and epstein-barr virus in dually infected body cavity lymphoma cells. | the bc-1 cell line, derived from a body cavity-based, b-cell lymphoma, is dually infected with epstein-barr virus (ebv) and kaposi's sarcoma-associated herpesvirus (kshv). in these studies, the relationships between these two gammaherpesviruses and bc-1 cells were characterized and compared. single-cell cloning experiments suggested that all bc-1 cells contain both genomes. in more than 98% of cells, both viruses were latent. the two viruses could be differentially induced into their lytic cycle ... | 1997 | 8985352 |
| kaposi's sarcoma-associated herpesvirus gene expression in endothelial (spindle) tumor cells. | the recent discovery of dna sequences of a new human herpesvirus in kaposi's sarcoma (ks) has fueled speculation that this virus might cause ks. the mere presence, however, of a virus in a complex multicellular tumor like ks could just as well be construed as evidence of a passenger agent. we sought stronger evidence linking the ks-associated herpesvirus (kshv) to tumor formation by using in situ hybridization to investigate the specificity, constancy, and timing of kshv gene expression in ks tu ... | 1997 | 8985403 |
| oral manifestations associated with human immunodeficiency virus infection in a spanish population. | a study was made of the oral manifestations in 396 patients with human immunodeficiency virus (hiv) infection. the following risk groups were established: intravenous drug users (79.5%), homosexuals (7.8%), homosexual intravenous drug users (3.3%), heterosexuals (8.1%) and hemophiliacs/transfusion patients (1.3%). the oral lesions, in decreasing order of frequency, were: periodontal disease (78.28%), candidiasis (65.65%), hairy leukoplakia (16.16%), herpes simplex virus lesions (5.30%). kaposi's ... | 1996 | 8986962 |
| characterization of ribonucleoprotein complexes containing an abundant polyadenylated nuclear rna encoded by kaposi's sarcoma-associated herpesvirus (human herpesvirus 8). | infection with kaposi's sarcoma-associated herpesvirus (kshv) (also called human herpesvirus 8) is strongly linked to all forms of kaposi's sarcoma. we have previously identified two polyadenylated kshv transcripts that are actively transcribed in kaposi's sarcoma (ks) tumors and in kshv-infected b-lymphoma cells. one of these rnas (termed t1.1 or nut-1 rna) is a 1.1-kb transcript present in a subpopulation of ks tumor cells. this rna is localized to the nucleus of infected cells and has no open ... | 1997 | 8995643 |

| a single 13-kilobase divergent locus in the kaposi sarcoma-associated herpesvirus (human herpesvirus 8) genome contains nine open reading frames that are homologous to or related to cellular proteins. | two small fragments of a novel human gammaherpesvirus genome known as kaposi's sarcoma (ks)-associated herpesvirus or human herpesvirus 8 (hhv-8) have been shown to be present in virtually all aids and non-aids ks lesions, as well as in body cavity-based lymphomas (bcbl) and in multicentric castleman's disease. we have extended those studies by identifying and sequencing a third fragment of hhv-8 dna encoding a viral thymidylate synthetase (ts) gene. use of this viral ts fragment as a probe led ... | 1997 | 9032328 |
| kaposi's sarcoma-associated herpesvirus encodes a functional cyclin. | kaposi's sarcoma-associated herpesvirus (kshv) (also called human herpesvirus 8) is consistently found in kaposi's sarcoma lesions and in body-cavity-based lymphomas. a 17-kb kshv lambda clone was obtained directly from a kaposi's sarcoma lesion. dna sequence analysis of this clone identified an open reading frame which has 32% amino acid identity and 53% similarity to the virus-encoded cyclin (v-cyclin) of herpesvirus saimiri (hvs) and 31% identity and 53% similarity to human cellular cyclin d2 ... | 1997 | 9032330 |
| kaposi's sarcoma-associated herpesvirus: a lymphotropic human herpesvirus associated with kaposi's sarcoma, primary effusion lymphoma, and multicentric castleman's disease. | despite extensive epidemiological evidence suggesting that kaposi's sarcoma (ks) has an infectious origin, a specific viral association with ks had not been documented until recently, when two novel dna fragments were identified in ks lesional tissue from a patient with the acquired immunodeficiency syndrome (aids). these fragments belong to a previously unidentified human herpesvirus, called ks-associated herpesvirus (kshv), or human herpesvirus 8. although this virus is generally absent from n ... | 1997 | 9044510 |
| progressive loss of cd8+ t cell-mediated control of a gamma-herpesvirus in the absence of cd4+ t cells. | a unique experimental model has been developed for dissecting the integrity of cd8+ t cell-mediated immunity to a persistent gammaherpesvirus under conditions of cd4+ t cell deficiency. respiratory challenge of major histocompatibility complex class ii -/- and +/+ c57bl/6j mice with the murine gammaherpesvirus 68 (mhv-68) leads to productive infection of both lung and adrenal epithelial cells. virus titers peak within 5-10 d, and are no longer detected after day 15. persistent, latent infection ... | 1996 | 9064346 |
| high incidence of kaposi's sarcoma-associated herpesvirus and epstein-barr virus in tumor lesions and peripheral blood mononuclear cells from patients with kaposi's sarcoma in uganda. | with the advent of aids, kaposi's sarcoma (ks) has become one of the leading malignancies in sub-saharan africa. recently, dna sequences from a new human herpesvirus called ks-associated herpesvirus (kshv) or human herpesvirus type 8 have been found in ks tumor lesions in high frequency. analyses of tumor lesions from 38 ugandan ks patients indicated a uniform presence of kshv in ks tumor lesions as revealed by polymerase chain reaction and southern hybridization. in contrast, only 31% (11/36) o ... | 1997 | 9086156 |
| [pulmonary kaposi's sarcoma in a patient with the acquired immunodeficiency syndrome]. | cutaneous kaposi's sarcoma (ks) is a well-known manifestation of the acquired immunodeficiency syndrome, but pulmonary ks is very rare in japan. we encountered a 27-year-old japanese, homosexual man who had extensive pulmonary ks. he came to our hospital because of a cough and dyspnea. on admission, there were some small nodules on the skin, and examination of a biopsy specimen led to the diagnosis of ks. the test for the human immunodeficiency virus antibody was positive and the cd4+ cell count ... | 1997 | 9103865 |

| kaposi's sarcoma and its management in aids patients. recommendations from a scandinavian study group. | ks is the most frequent malignancy in homo/bisexual male aids patients, affecting more than 30% of these patients. ks may present itself as a few innocent cutaneous lesions or may show progression resulting in severe morbidity and mortality. approximately half of the patients may develop severe progressive disease. the prognosis of patients with progressive disease is poor, with a median survival of less than 6 months. there is no cure for aids-related ks, but several therapies are available for ... | 1997 | 9112290 |
| detection of serum antibodies to a kaposi's sarcoma-associated herpesvirus-specific peptide. | kaposi's sarcoma (ks)-associated herpesvirus/human herpesvirus type 8 (kshv/hhv-8) may play an etiologic role in the pathogenesis of ks. in an attempt to assess kshv/hhv-8 infection, an elisa was developed using an 18-amino acid peptide from a putative minor capsid protein of kshv/hhv-8 conjugated to bovine serum albumin. overall, sera from human immunodeficiency virus type 1 (hiv-1)-positive patients with ks had a higher reactivity in the assay than did sera from hiv-1-positive patients without ... | 1997 | 9129068 |
| exacerbations of clinical symptoms in human immunodeficiency virus type 1-infected patients with multicentric castleman's disease are associated with a high increase in kaposi's sarcoma herpesvirus dna load in peripheral blood mononuclear cells. | the epidemiologic link between multicentric castleman's disease (mcd) and kaposi's sarcoma (ks) and the high frequency of ks herpesvirus (kshv) detection in both diseases raise the question of a role of this new virus in the pathogenesis of mcd. to explore this hypothesis, the kshv dna load was investigated in peripheral blood mononuclear cells of 3 human immunodeficiency virus (hiv)-infected patients with mcd at different points during the clinical course. clinical parameters, such as fever and ... | 1997 | 9129085 |

| hiv-1 tat induces the expression of the interleukin-6 (il6) gene by binding to the il6 leader rna and by interacting with caat enhancer-binding protein beta (nf-il6) transcription factors. | human immunodeficiency virus type 1 (hiv-1) infection is associated with severe psoriasis, b cell lymphoma, and kaposi's sarcoma. a deregulated production of interleukin-6 (il6) has been implicated in the pathogenesis of these diseases. the molecular mechanisms underlying the abnormal il6 secretion of hiv-1-infected cells may include transactivation of the il6 gene by hiv-1. here we report the molecular mechanisms of tat activity on the expression of the il6 gene. by using 5' deletion mutants of ... | 1997 | 9169458 |
| detection of human herpes virus 8 dna and sequence polymorphism in classical, epidemic, and iatrogenic kaposi's sarcoma in south africa. | the aetiology and detection of human herpes virus type 8 (hhv-8) dna sequences in kaposi's sarcoma (ks) is a matter of intense investigation. we report on the detection of hhv-8 dna and sequence polymorphism in different clinicopathological subtypes of cutaneous ks samples from south africa. the diagnosis was confirmed by histological examination in all cases. six patients had classic ks (cks), 3 epidemic ks (eks), and 3 iatrogenic ks (iks). a nested polymerase chain reaction (pcr) assay was use ... | 1997 | 9179764 |
| no evidence of kshv/hhv-8 in mycosis fungoides or associated disorders. | the recently discovered human virus known as kaposi's sarcoma-associated herpesvirus (kshv) or human herpesvirus-8 (hhv-8) has been associated with body-cavity-based lymphomas in aids patients. it is most closely related to two other herpesviruses, the epstein-barr virus and herpesvirus saimiri, which are known to be associated with lymphomas in humans and nonhuman primates, respectively. to determine whether kshv/hhv-8 is involved in the pathogenesis of mycosis fungoides (mf) and related disord ... | 1997 | 9182822 |
| kaposi's sarcoma-associated herpesvirus infection of bone marrow dendritic cells from multiple myeloma patients. | kaposi's sarcoma-associated herpesvirus (kshv) was found in the bone marrow dendritic cells of multiple myeloma patients but not in malignant plasma cells or bone marrow dendritic cells from normal individuals or patients with other malignancies. in addition the virus was detected in the bone marrow dendritic cells from two out of eight patients with monoclonal gammopathy of undetermined significance (mgus), a precursor to myeloma. viral interleukin-6, the human homolog of which is a growth fact ... | 1997 | 9188529 |

| herpes virus (kshv) associated kaposi sarcoma in a 3-year-old child with non-hiv-induced immunodeficiency. | a 3-year-old boy of german descent suffered from two episodes of streptococcus pneumoniae meningitis within 2 months. one month previously, the first skin lesion of kaposi sarcoma (ks) had been observed behind his right ear. during the following 2 years ks disseminated not only mucocutaneously but also to visceral organs. immunological evaluation revealed severe lymphocytopenia with reduced helper/suppressor t-cell ratio and impaired humoral immune response to pneumococci. extensive laboratory t ... | 1997 | 9208237 |
| kaposi's sarcoma-associated herpesvirus/human herpesvirus-8: a new virus in human pathology. | the discovery of a new human herpesvirus in kaposi's sarcoma (ks) tissue of patients with aids has opened up new vistas in virology and oncology. this herpesvirus was first descriptively named ks-associated herpesvirus (kshv), but was recently renamed human herpesvirus 8 (hhv8). kshv/hhv8 dna has been found in all forms of ks, suggesting that it might be involved in the pathogenesis of ks. in addition, kshv/hhv8 can be detected in both malignant and benign lymphoproliferative disease. kshv/hhv8 ... | 1997 | 9216532 |
| simultaneous onset of primary cutaneous b-cell lymphoma and human herpesvirus 8-associated kaposi's sarcoma. | we report the simultaneous occurrence of kaposi's sarcoma (ks) and primary cutaneous b-cell lymphoma (cbcl) of the leg in a 79-year-old woman, seronegative for hiv-1, htlv-1 and htlv-2. the cbcl underwent complete clinical remission after local radiotherapy, whilst the ks became disseminated within a year following diagnosis. however, 2 years after the diagnosis of ks, the patient died with neurological symptoms. these were presumed to be due to involvement of the central nervous system by lymph ... | 1997 | 9217827 |
| kaposi's sarcoma-associated herpesvirus/human herpesvirus type 8 encephalitis in hiv-positive and -negative individuals. | kaposi's sarcoma-associated herpesvirus (kshv) human herpesvirus type 8 (hhv-8) has been associated with kaposi's sarcoma and a variety of benign lymphoid proliferations including angioimmunoblastic lymphadenitis with dysproteinemia and castleman's disease. kshv/hhv-8 has also been associated with inflammatory conditions including interstitial pneumonitis. although herpesviruses are commonly associated with encephalitis in immunosuppressed individuals, kshv/hhv-8 has not previously been associat ... | 1997 | 9233458 |
| a kaposi's sarcoma-associated herpesvirus-encoded cytokine homolog (vil-6) activates signaling through the shared gp130 receptor subunit. | the present studies analyzed the biologic activity of a gene product (vil-6) encoded by the recently discovered kaposi's sarcoma-associated herpesvirus (kshv) bearing 24.8% amino acid identity with human interleukin-6 (huil-6). based on this similarity, we hypothesized that this viral homolog might trigger the jak/stat pathway, which typically is engaged by il-6 and other cytokines. activation of receptor-associated janus tyrosine kinases (jaks) results in the subsequent phosphorylation of signa ... | 1997 | 9235971 |

| epstein-barr virus latent gene expression in primary effusion lymphomas containing kaposi's sarcoma-associated herpesvirus/human herpesvirus-8. | primary effusion (body cavity-based) lymphoma (pel) is a recently recognized subtype of malignant lymphoma that exhibits distinctive clinical and biological features, most notably its usual infection with the kaposi's sarcoma-associated herpesvirus (kshv). the vast majority of cases also contain epstein-barr virus (ebv). this dual viral infection is the first example of a consistent dual herpesviral infection in a human neoplasm and provides a unique model to study viral interactions. we analyze ... | 1997 | 9242551 |
| kaposi's sarcoma-associated herpesvirus sequences in benign lymphoid proliferations not associated with human immunodeficiency virus. | kaposi's sarcoma-associated herpesvirus (kshv) dna sequences have been identified in approximately 95% of kaposi's sarcoma (ks) lesions and primary effusion lymphomas (pels), suggesting a pathogenetic role for this virus in these lesions. however, kshv has also been identified in a variety of specimens, including lymph nodes, peripheral blood b cells, semen, and prostate tissue, with varying frequencies. this suggests that kshv, like epstein-barr virus, may be ubiquitously distributed. to evalua ... | 1997 | 9264363 |
| kaposi's sarcoma as manifestation of immunosuppression in organ transplant recipients. | we report 2 patients, negative for human immunodeficiency virus (hiv) antibodies, who developed generalized kaposi's sarcoma (ks), one 5 months after renal transplantation while receiving cyclosporin a and prednisone, and the other 24 months after heart transplantation while receiving cyclosporin a, azathioprine and prednisone. reduction of the immunosuppressive therapy combined with chemotherapy and radiotherapy in both cases led to a remission of ks without development of transplant rejection. | 1997 | 9267755 |

| human herpesvirus 8 dna sequences in blistering skin from patients with pemphigus. | human herpesvirus 8 (hhv-8) has been detected in kaposi sarcoma (ks) and other lesions in patients both seropositive and seronegative for the human immunodeficiency virus (hiv). kaposi sarcoma has been reported to develop in a disproportionate number of patients with pemphigus. since hhv-8 is so strongly associated with ks, we wondered whether hhv-8 is present in pemphigus lesions from patients without ks or hiv infection. pemphigus lesions and skin from healthy individuals were coded in a blind ... | 1997 | 9382563 |
| establishment of hhv-8-positive and hhv-8-negative lymphoma cell lines from primary lymphomatous effusions. | primary lymphomatous effusions are represented by cases of non-hodgkin's lymphoma (nhl) which grow in liquid phase in the serous body cavities in the absence of solid tumour masses. based on morphologic, immunophenotypic, virologic and genotypic features, primary lymphomatous effusions are distinguished into body cavity-based lymphoma (bcbl), burkitt's lymphoma (bl) and immunoblastic large-cell lymphoma. the histogenesis and pathogenesis of primary lymphomatous effusions are virtually unclarifie ... | 1997 | 9389573 |
| absence of human herpesvirus 8 and epstein-barr virus genome sequences in cutaneous epithelial neoplasms arising in immunosuppressed organ-transplant patients. | recent studies have implicated herpesvirus 8 and epstein-barr virus in the development of cutaneous malignancies in immunosuppressed patients. in order to examine the strength of this association, we examined 37 malignant, pre-malignant and benign cutaneous epithelial neoplasms removed from immunosuppressed organ recipients for the presence of human herpesvirus 8 and epstein-barr viral genome sequences using polymerase chain reaction (pcr) and in situ hybridization. we examined 2 actinic keratos ... | 1997 | 9404853 |
