Zinc and cadmium hyperaccumulation by Thlaspi caerulescens from metalliferous and nonmetalliferous sites in the Mediterranean area: implications for phytoremediation
Growth, tolerance and zinc and cadmium hyperaccumulation of Thlaspi caerulescens populations from three metal contaminated soils and three normal soils were compared under controlled conditions.Expand

MHC-I–restricted presentation of HIV-1 virion antigens without viral replication
Dendritic cells and macrophages can process extracellular antigens for presentation by MHC-I molecules. This exogenous pathway may have a crucial role in the activation of CD8+ cytotoxic TExpand

HIV F/3' orf encodes a phosphorylated GTP-binding protein resembling an oncogene product
Apart from the retroviral gag, pol and env 1,2, the HIV genome contains the F (3'orf) gene which encodes a polypeptide of 206 amino acids which is myristylated at the N-terminal and whose function isExpand

Gag-specific cytotoxic responses to HIV type 1 are associated with a decreased risk of progression to AIDS-related complex or AIDS.
The duration of human immunodeficiency virus (HIV-1) infection prior to the development of AIDS is variable, and for most patients the exact time of infection is not known. A group of 38Expand

A novel flow cytometric assay for quantitation and multiparametric characterization of cell-mediated cytotoxicity.
Cell-mediated cytotoxicity is a crucial mechanism involved in several fundamental immunological processes such as protection against intracellular pathogens or termination of an immune response. ThisExpand

Autoantibodies typical of non‐organ‐specific autoimmune diseases in HIV‐seropositive patients
ObjectiveTo analyse serological aspects of systemic autoimmunity in HIV-1-seropositive patients and in individuals at risk for AIDS. Design and methodsThe reactivity of antibodies in the serum of 100Expand

Combined Genotypes of CCR5, CCR2, SDF1, and HLA Genes Can Predict the Long-Term Nonprogressor Status in Human Immunodeficiency Virus-1-Infected Individuals
Human immunodeficiency virus (HIV)-1-infected long-term nonprogressors (LT-NP) represent less than 5% of HIV-1-infected patients. In this work, we tried to understand whether combined genotypes ofExpand

The cytopathic effect of HIV is associated with apoptosis.
Large amounts of histones, H1, H2A, H2B, H3, and H4, were observed in total extracts of T4 lymphocytes and derived cell lines infected with the human immunodeficiency virus (HIV) type 1 or type 2.Expand

Membrane expression of HIV envelope glycoproteins triggers apoptosis in CD4 cells.
The cytopathic effect of HIV-1 and HIV-2 in CD4+ lymphocytes has been shown to be associated with apoptosis or programmed cell death. Using different experimental conditions, we demonstrate here thatExpand
