Abstract Context: The Women and Infants Transmission Study is a prospective natural
history study that has been enrolling HIV-1-infected pregnant women and their infants since …

The rate of development of disease varies considerably among human immunodeficiency
virus type 1 (HIV-1)-infected children. The reasons for these observed differences are not …

The V3 region of the human immunodeficiency virus type 1 (HIV-1) envelope protein is
known to have a major influence on macrophage tropism as well as the ability to cause …

About one-third of vertically HIV-1 infected infants develop AIDS within the first months of life;
the remainder show slower disease progression. We investigated the relationship between …

Abstract The Human Immunodeficiency Virus type 1 (HIV-1) is classified into genetic groups,
subtypes and sub-subtypes which show a specific geographic distribution pattern. The HIV-1 …

Cytokines are potent stimuli for CD4+-T-cell differentiation. Among them, interleukin-12 (IL-
12) and IL-4 induce naive CD4+ T cells to become T-helper 1 (Th1) or Th2 cells …

Human immunodeficiency virus type 1 (HIV-1) non-syncytium-inducing (NSI) strains
predominantly use the chemokine receptor CCR5, while syncytium-inducing (SI) strains use …

X-ray crystallographic structures of two human, anti-V3 HIV-1 neutralizing antibodies, 447-
52D and 2219, show how the two antibodies use different strategies for their cross-reactivity …

Phylogenetic analysis was used to study in vivo genetic variation of the V3 region of human
immunodeficiency virus type 1 in relation to disease progression in six infants with vertically …

The disulfide bridge closed cyclic peptide corresponding to the whole Consensus V3 loop of
the envelope protein gp120 of HIV‐1 was examined by proton 2D‐NMR spectroscopy in …
