Novel Entry Inhibitor May Provide Vaccine-like Protection Against HIV

A potential new therapy using a molecule that mimics both the CD4 receptor and the CCR5 co-receptor can stop an HIV-like virus from entering host cells, researchers reported in the February 18 online edition of Nature. Monkeys given gene therapy to produce the eCD4-Ig protein did not become infected after repeated virus exposures, suggesting it may be an effective HIV vaccine alternative as well as a long-acting therapy.

Neutralizing Antibodies from Llamas Provide Clues for HIV Vaccine Research

Heavy-chain broadly neutralizing antibodies produced by llamas can neutralize a wide range of circulating HIV virus strains, suggesting that immunization could potentially induce protective antibodies against HIV in humans, according to a report in the December 18 edition of PLoS Pathogens.

HIV R4P: The Immunity Project -- An Open-Access T-Cell Vaccine for HIV Infection

Microparticles containing conserved HIV epitopes may be able to prime antigen-presenting dendritic cells, which in turn activate antigen-specific CD8 killer T-cells, offering a potential new approach for developing T-cell-based preventive or therapeutic HIV vaccines, researchers with the open-access Immunity Project reported at the HIV Research for Prevention (HIV R4P) conference last week in Cape Town.

HIV R4P: RV144 HIV Vaccine's Effects Were Real -- and Could Be Made to Work Better

Findings from further studies using a reformulation of the only HIV vaccine that has ever worked in a large efficacy trial were presented at the recent HIV Research for Prevention conference (HIVR4P) in Cape Town. They showed evidence of stronger antibody responses, and in-depth analysis of these responses suggests that by further developing a similar vaccine, it may be possible to push the immune system to generate an antibody response to HIV that is sufficiently strong to prevent most infections.
