A team of researchers from Purdue University have made an amazing discovery regarding the West Nile virus: when a certain antibody binds to it, it manages to lock up the infection mechanism and neutralize it.This could be a major step towards developing a vaccine against this mosquito-borne illness, said Michael Ross... |

A study carried out at the University of Pennsylvania School of Veterinary Medicine has discovered the function of one of the most ancient antibodies in the animal reign, the immunoglobulin that ensures mucosal immunity.This antibody is very important in the guts of fish and it will help to better understand the ... |

The intricate processes behind newborns developing an immune system have been exposed for the first time by scientists at the California Institute of Technology. Using gold atoms to track down proteins inside the new body, they uncovered that the antibodies transmitted by the mother through breast milk or through the... |

A breakthrough in testing for HIV has been achieved: no more blood analysis is required, since a new saliva-based test comes with results in just 20 minutes, as described in the PLoS Medicine journal. The new technique uses the oral mucosal transudate (OMT), a liquid released at the base of the gums that later turns ... |

Criminals have no chance. A new human identification test relying on antibodies seems to be faster and cheaper than DNA testing, besides requiring minimal training in the field, improving the arsenal of detectives, forensic experts and the military. Our antibody signature is as unique as our DNA, and antibodies, prot... |

In the race for an anti-HIV vaccine, scientists have just opened another chapter, discovering the molecular mechanisms that make a few antibodies effective against HIV, while most of them fail. Vaccines have been fighting for long successfully against many infectious diseases, but scientists still do not know how exa... |

H5N1 has severely affected the poultry industry in several Asian countries and made over 200 human victims. People seem to get the infection after a close contact with diseased birds. But the fear comes from a possible mutation or combination with common human flu virus, a fact that could cause a global pandemic as b... |

The antibodies are blood proteins developed in order to detect and attack germs, like bacteria and viruses. But in the end, their abilities are limited by the genetic information carried by each one of us. This limitation could be enhanced by a new research made at the Oxford University. Here, a research team has a... |

Viruses are entities at the limit of living and non-living. Unlike bacteria, a virus can not feed and reproduce by itself; instead, it needs a host cell to accomplish these functions. That's why they induce diseases; over 50 % of the human diseases and 90 % of the human infections are virus-provoked. A virus is ... |
