OBJECTIVE To investigate the mechanisms and spectrum of the anti-HIV activity of chloroquine. DESIGN AND METHODS MT-4 cells or peripheral blood mononuclear cells were infected with X4, R5 or R5/X4 HIV-1 strains from clades A-E and HIV-2. The cells were then treated with clinically relevant and achievable chloroquine concentrations (i.e. 0-12.5 microM), so(More)
Glioblastoma Multiforme (GBM) is an incurable malignancy. GBM patients have a short life expectancy despite aggressive therapeutic approaches based on surgical resection followed by adjuvant radiotherapy and concomitant chemotherapy. Glioblastoma growth is characterized by a high motility of tumour cells, their resistance to both chemo/radio-therapy,(More)
It has been suggested that iron-deficient rats have lower bone mass than iron-replete animals, but a clear association between bone and iron repletion has not been demonstrated in humans. A growing body of evidences also suggests a relation between lipid oxidation and bone metabolism and between iron metabolism and LDL oxidation. Iron availability to cells(More)
BACKGROUND there is a dramatic need for drugs with anti-HIV-1 activity that are affordable for resource-poor countries. Chloroquine (CQ) is one such drug. OBJECTIVES to review the data indicating that CQ has anti-HIV-1 activity. RESULTS chloroquine (CQ) and its derivative hydroxychloroquine (HCQ) are endowed with a broad anti-HIV-1 activity inhibiting(More)
Glioblastomas (GBMs) are the most lethal primary brain tumours. Increasing evidence shows that brain tumours contain the population of stem cells, so-called cancer stem cells (CSCs). Stem cell marker CD133 was reported to identify CSC population in GBM. Further studies have indicated that CD133 negative cells exhibiting similar properties and are able to(More)
Human immunodeficiency virus-1 (HIV-1) Tat, a nuclear transactivator of viral gene expression, has the unusual property of being released by infected cells. Recent studies suggest that extracellular Tat is partially sequestered by heparan sulfate proteoglycans. As a consequence, Tat is concentrated on the cell surface and protected from proteolytic(More)
Interleukin-18 (IL-18) is a recently identified immunoregulatory cytokine expressed by activated macrophages, that induces production of interferon-gamma (IFN-gamma) and Th-1 development. Recently some investigators reported controversial in vitro data on IL-18 stimulation of HIV-1 replication in several cell lines. In the present study the effect of IL-18(More)
Dysfunction of neutrophils (polymorphonuclear leukocytes [PMNL]) and macrophagic cells occurs as a consequence of human immunodeficiency virus type 1 (HIV-1) infection. Macrophages contribute to the resolution of early inflammation ingesting PMNL apoptotic bodies. This study investigated macrophage ability to phagocytose PMNL apoptotic bodies in patients(More)
Different haptoglobin (Hp) phenotypes play a role in several pathologic processes including infectious diseases. In order to evaluate the role of iron storage and metabolism in susceptibility to herpetic manifestations, we studied the frequency of the Hp phenotypes and iron metabolism in patients affected by H. Simplex virus 1 or 2 (HSV-1 or HSV-2),(More)
The particular combination of polydeoxyribonucleotides, l-carnitine, calcium ions, proteolytic enzyme and other ingredients acts in a synergetic way in the regeneration of skin and connective tissues. This new formulation of active principles was tested in vitro as a cell and tissue culture medium and in vivo for various preparations in support of tissue(More)
