Naturally-occurring strains of human immunodeficiency virus (HIV) can vary considerably in their in vitro biological properties, and such differences may also be reflected in their in vivo pathogenesis. In an attempt to define genetic determinants of viral pathogenicity, we have molecularly cloned, sequenced and charac

OBJECTIVE: Biological characterization of HIV-2 strains from peripheral blood mononuclear cells (PBMC) of patients from the Ivory Coast . METHODS: The host range of 7 different HIV-2 strains was determined by culturing them in PBMC from humans and non-human primates and in established T.B. and monocyte cell lines. Infe

OBJECTIVE: We previously reported the isolation of persistently infected MT-4 cells after drastic cytolysis by HIV-1 infection. Molecular-biological analyses indicated that MT-4 cells primarily infected with genomically defective HIV-1 survived the infection. To examine the possible identification of HIV-1 gene(s) invo


Genes in the 3' end of the HIV-1 genome control HIV replication and cytopathology.

OBJECTIVE: HIV-1 isolates, besides extensive sequence variation, exhibit differences in their host cell range and vary in their ability to cause cytopathic effects in their host cells, form plaques in the MT-4 cell line and down modulate the CD4 receptor molecule. Some of these properties have been correlated with path


Infection of hemopoetic progenitor cells with HIV1.

OBJECTIVE: To study direct infection of hemopoetic progenitor cells in vitro as a possible mechanism of suppression of hemopoesis in ARC and AIDS. METHODS: Highly purified Cd34+ hemopoetic progenitor cells from normal donors were cocultured with HIV or HIV-infected macrophages in serum-free low density suspension cultu

OBJECTIVE: HIV-1 infection is frequently associated with anemia and leukopenia. The replication of HIV in bone marrow stem cells has been proposed as a potential explanation. METHODS: To study this hypothesis we purified CD34+ cells (which are highly enriched in hematopoietic progenitors) from the bone marrows of 14 HI


Investigation of HIV infection in bone marrow hemopoietic stem/progenitor cells.
Int Conf AIDS 1990 Jun 20-23; 6:151 (abstract no. F.A.301)
Davis BR, Marx J, Johnson C, Berry M, Schwartz D; Medical Research Institute, San Francisco, CA, USA
OBJECTIVES: 1) To establish the presence or absence of HIV provirus in CD34+ bone marrow stem/progenitor cells isolated from HIV+ individuals. 2) To determine whether the suppression of hemopoiesis frequently seen in ARC/AIDS is due to stem/progenitor cell infection. METHODS: CD34+ cells were immunomagnetically purifie


Expression of HIV-1 in glial cells.

Herrmann R, Ludwigsen A, Chuah M, Brack-Werner R, Kohleisen B, Kleinschmidt A, Erfle V; GSF-Abt. Mol. Zellpath. Neuherberg, FRG
OBJECTIVE: Analysis of HIV-1 expression using a persistently infected glial cell line as a model system for virus latency. METHODS: a) A glial cell line persistently infected with HIV-1 (TH4-7-5) was analysed for expression of HIV-1 antigens by immunoperoxidase staining and/or Western blotting using mabs against struct


HIV-infected macrophage soluble factors alter human brain tissue.

Pulliam L, Tang N, Herndier B, McGrath M; University of California, San Francisco, California, USA
OBJECTIVE: We wished to establish a human model for AIDS dementia and pursue the hypothesis that this dementia may be a result of an indirect mechanism produced by HIV-infected macrophages. METHODS: Human brain cell aggregates were prepared from 7 different specimens. Aggregates were treated with HIV-infected macrop
