BACKGROUND The cellular reservoirs of Kaposi's sarcoma-associated herpesvirus (KSHV) and the exact nature of the putative KSHV-infected circulating precursor of spindle cells of Kaposi's sarcoma (KS) still remain poorly defined. Because KS spindle cells are thought to be of endothelial origin, and because mature endothelial cells do not sustain persistent(More)
This article describes the synthesis and the biological evaluation of two sets of benzothiazole derivatives bearing at C-2 an arylamide (1a–e, 2a–e) or an arylurea (3a–d, 4a–d) moiety. Five compounds (3d and 4a–d) were selected and screened by the National Cancer Institute for the in vitro primary anticancer assay against a panel of 60 human tumor cell(More)
The peculiar localization of body cavity lymphomas implies a specific contribution of the intracavitary microenvironment to the pathogenesis of these tumors. In this study, primary effusion lymphoma (PEL) was used as a model of body cavity lymphoma to investigate the role of mesothelial cells, which line the serous cavities, in lymphoma progression. The(More)
Sir, We refer to the letter by JM Wojcicki (2003), which is an interesting contribution towards attempts to elucidate risk factors for transmission of the human herpesvirus 8 or Kaposi's sarcoma-associated herpesvirus (HHV-8/KSHV). The author emphasises the prevalence of nonsexual intrafamilial horizontal transmission, the frequent seroconversion in(More)
PEL is a B-cell non-Hodgkin lymphoma, occurring predominantly as a lymphomatous effusion in body cavities, characterized by aggressive clinical course, with no standard therapy. Based on previous reports that PEL cells display a Warburg phenotype, we hypothesized that the highly hypoxic environment in which they grow in vivo makes them more reliant on(More)
BACKGROUND Human herpesvirus-8 (HHV-8) is the etiological agent of Kaposi's sarcoma (KS) and of some lymphoproliferative disorders of B cells. Most malignancies develop after long-lasting viral dormancy, and a preventing role for both humoral and cellular immune control is suggested by the high frequency of these pathologies in immunosuppressed patients. B(More)
Herpesvirus infection of placenta may be harmful in pregnancy leading to disorders in fetal growth, premature delivery, miscarriage, or major congenital abnormalities. Although a correlation between human herpesvirus 8 (HHV-8) infection and abortion or low birth weight in children has been suggested, and rare cases of in utero or perinatal HHV-8(More)
We present here a case of immune reconstitution inflammatory syndrome associated with Kaposi’s sarcoma (KS-IRIS) developed in an AIDS patient two months after initiation of antiretroviral therapy (ART). Baseline characteristics of this IRIS-KS case, within a cohort of 12 naïve AIDS-KS patients, were analyzed. No statistically significant differences in CD4(More)
This manuscript describes the synthesis of a new series of 2-amino-6-(trifluoromethoxy)benzoxazole derivatives (1–5) and a benzothiazine derivative (6) structurally related to riluzole, the only neuroprotective drug currently approved for the treatment of the amyotrophic lateral sclerosis. Preliminary results indicate that the synthesized compounds, in(More)
