Differential regulation of HIV-1 fusion cofactor expression by CD28 costimulation of CD4+ T cells.
Activation of CD4(+) T lymphocytes from human immunodeficiency virus-type 1 (HIV-1)-infected donors with immobilized antibodies to CD3 and CD28 induces a virus-resistant state. This effect is… Expand
Effects of Lime and Calcium on Root Development and Nodulation of Clovers
Acidic soils can reduce the nodulation of forage legumes. Studies with a Gilpin series silt loam (fine loamy, mixed mesic, Typic Hapludult) from New, WV, were conducted to determine the effects of… Expand
Infectious Molecular Clones with the Nonhomologous Dimer Initiation Sequences Found in Different Subtypes of Human Immunodeficiency Virus Type 1 Can Recombine and Initiate a Spreading Infection In…
ABSTRACT Recombinant forms of human immunodeficiency virus type 1 (HIV-1) have been shown to be of major importance in the global AIDS pandemic. Viral RNA dimer formation mediated by the dimerization… Expand
Influenza virus upregulates CXCR4 expression in CD4+ cells.
We examined the effect of prior influenza virus infection on the susceptibility of CD4+ cells to HIV-1 infection. Influenza virus infection of HeLa-CD4 cells resulted in a marked increase in… Expand
Exposure of human CD34+ cells to human immunodeficiency virus type 1 does not influence their expansion and proliferation of hematopoietic progenitors in vitro.
The susceptibility of highly purified human CD34+ cells to monocytotropic (Ba-L) and lymphotropic (A018-post) strains of human immunodeficiency virus-1 (HIV-1) was examined. Liquid cultures initiated… Expand
