According to new scientific evidence, it would appear that the retroviruses from which the Human Immunodeficiency Virus (HIV) evolved have been plaguing the animal world since 100 million years ago. The new time frame is about 85 million years 'older' than first thought, which brings into focus the need to ... |

In the largest clinical trial aimed at observing the effects of a new, combo vaccine against the Human Immunodeficiency Virus (HIV), results were only moderately successful. Two older vaccines were combined in the current studies, so that scientists could assess their efficiency when working together. But the effort ... |

One of the most impressive things about our immune system is that it is essentially everywhere in the body. Where there's blood, there are bound to be at least a few white blood cells (WBC) just patrolling around and doing their job. When a chemical trigger runs through the blood, announcing that a pathogen has ... |

Scientists were able recently to demonstrate that it's not only the genetic sequence of the Human Immunodeficiency Virus (HIV) that makes it so dangerous, but also its architecture. The term is used to compare the way the virus is put together with an electrical diagram, for example. The experts in charge of the... |

The Human Immunodeficiency Virus (HIV) is one of the most dangerous and widespread in the world today, and its basic survival tactic is to “cloak” itself from the immune system, so as not to get detected. It does that by mutating extensively and over short periods of time and first attacking the fighter-c... |

HIV has remained impervious to advancements in medicine over the last 25 years, and all the research paths explored by scientists seem to dead-end at some point. The current approach is to engineer super-molecules made from compounds found outside the human body, and to make them face the virus head-on. A new method ... |

Though some think that the Human Immunodeficiency Virus (HIV) cannot be attacked by the immune system at all, this is very wrong, say scientists.
