On the establishment of shielding immune cells avoid HIV viral antigens identified protein adsorption and the establishment of "biological trap" induce HIV models Summary : HIV is the human immunodeficiency virus caused AIDS virus, AIDS is not currently be fully human control, AIDS vaccine is being developed, but because the virus genetic diversity potential to change the topic of the complexity of this ban from the incidence of HIV spread T4 cells in the mechanisms by, proposed changes T4 lymphocyte surface protein CD4 receptors structure as to avoid HIV adsorption, and the establishment of "biological trap" booby HIV idea to try to turn on AIDS treatment to the conversion of protein structure and function, as well as synthetic direction.

AIM: To isolate bioactive secondary metabolites from the fruits of Schisandra rebriflora Rehd. et. Wils and study their effects on HIV-1 infectivity. METHODS: Inhibition of syncytia formation, HIV-1 reverse transcriptase and protease, protection of HIV-1 infected cells, level of HIV-1 p24 antigen,blockage of fusion were detected. RESULTS: A lignan compound, named rubrifloralignan A, was first isolated as a natural product with modest inhibition effects on syncytium formation and HIV- 1 replication and could protect HIV-1 infected cells with weak inhibition effects on fusion and RT, but it showed no effects on the replication of HIV-1 chronic H9 and PR. CONCLUSION: Rubrifloralignan A is an efficient anti-HIV-1 product with effect on early stage of HIV-1 replication.

For most viruses,there is aneed for antimicrobials that target unique viral molecular properties.Acycloviris one such drug.It is activated into ahuman herpesvirusDNA polymerase inhibitor exclusively by HHV kinases and,thus,does not suppress other viruses.Here,we show that ACV suppresses HIV-1in HHV-coinfected human tissues,but not in HHV-free tissue or cell cultures.However,addition of HHV-6-infected cells renders these cultures sensitive to anti-HIV ACV activity.We hypothesized that such HIV suppression requires ACV phosphorylation by HHV kinases.Indeed,an ACV monophosphorylated prodrug bypasses the HHV requirement for HIV suppression.Furthermore,phosphorylated ACV directly inhibits HIV-1reverse transcriptase,terminating DNA chain elongation,and can trap RT at the termination site.These data suggest that ACV anti-HIV-1activity may contribute to the response of HIV/HHV-coinfected patients to ACV treatment and could guide strategies for the development of new HIV-1RT inhibitors.

With this in mind, the researchers then reanalysed data from knowingly HIV-positive heterosexual subjects in Uganda and Zambia who had HIV-negative sexual partners. Those with a viral load of one million particles per millilitre were more than ten times more likely to accidentally infect their partners each year than those with a load of one thousand.But when the researchers calculated the transmission potential over the entire predicted asymptomatic period, those with viral loads between ten thousand and a hundred thousand copies per millilitre of blood were the most likely to infect their partners. HIV-positive subjects with viral counts of 50,000 infected roughly twice as many people as those with counts of one million.
