Introduction Heterosexual transmission of the human immunodeficiency virus (HIV) leading to the acquired immunodeficiency syndrome (AIDS) continues to fuel a major global pandemic [1]. The identification of an immunization strategy that can protect against mucosal HIV transmission via the female genital tract thus should provide an essential mechanism for halting the spread of HIV/AIDS.
In the HIV research community, there is general consensus that both antibody and T-cell-mediated immune responses could contribute to an effective prophylactic vaccine [2,3]. An important role for serum neutralizing antibodies against viral surface protein antigens for protection has been demonstrated repeatedly for numerous other viral pathogens for which there are effective vaccines, including influenza, polio, hepatitis B virus, MUMPS, and measles [4–8].

By Kate Kelland LONDON Mon Nov 21, 2011 3:51pm IST LONDON (Reuters) - More people than ever are living with the AIDS virus but this is largely due to better access to drugs that keep HIV patients alive and well for many years, the United Nations AIDS programme (UNAIDS) said on Monday. In its annual report on the pandemic, UNAIDS said the number of people dying of the disease fell to 1.8 million in 2010, down from a peak of 2.2 million in the mid-2000s.
UNAIDS director Michel Sidibe said the past 12 months had been a "game-changing year" in the global AIDS fight. About 2.5 million deaths have been averted in poor and middle-income countries since 1995 due to AIDS drugs being introduced and access to them improving, according to UNAIDS. Much of that success has come in the past two years as the numbers of people getting treatment has increased rapidly. "Even in this time of public finance crises and uncertainty about funding, we're seeing results.

This is a solution RNA structure model of the HIV-1 dimerization initiation site in the kissing-loop dimer.[1] It has been shown that SL1 may provide a secondary binding site for the viral Rev protein.[15] The Rev protein is an essential HIV regulatory protein which increases the stability and transport of the unspliced viral RNA.[16] Stem-loop 2 (SL2) (also referred to as HIV-1 SD) consists of a highly conserved 19 nt stem-loop which has been shown by mutatagenis to modulate the splicing efficiency of HIV-1 mRNAs.[17] Stem-loop 4 (SL4) consists of a highly conserved 14 nt stem-loop that is located just downstream of the gag start codon.
The structure was confirmed by mutagenesis and has an NMR and mass spectrometric detection (MS3D).[17] It also may have coding and non-coding roles.

Human immunodeficiency virus type 1 dimerization initiation site. HIV - Wiki. The human immunodeficiency virus (HIV) is a lentivirus (slowly replicating retrovirus) that causes the acquired immunodeficiency syndrome (AIDS),[1][2] a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.
Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. Virology Classification Two types of HIV have been characterized: HIV-1 and HIV-2. Structure and genome Diagram of HIV HIV is different in structure from other retroviruses. This is, in turn, surrounded by the viral envelope that is composed of two layers of fatty molecules called phospholipids taken from the membrane of a human cell when a newly formed virus particle buds from the cell. Nef also interacts with SH3 domains. Tropism Diagram of the immature and mature forms of HIV.
