A group of investigators at the University of British Columbia (UBC) announces the discovery of a molecular pathway that is involved in the internal guidance system that allows immune cells to find and identify pathogen fragments.
This mechanism is therefore absolutely essential to our body's defenses. When th... |

Each year, the flu and cold epidemics strike in the general population without warning, but always around the same time. The pathogens spread like wildfire, and yet researchers still don't know precisely how this happens. A new research has recently taken a closer look at the issue. The situation is especially w... |

As most of you know, the only goal a pathogen has when invading the human body is ensuring its survival and multiplication; but now researchers suggest that some organisms are more cunning than others in doing so. A large portion of microorganisms that invade the body tend to enter cells immediately, where they begin... |

Biologists know that ants are just as vulnerable as we are to infections from fungi, parasites and bacteria. The small insects also have immune systems, but one major difference from humans is that their colony is their immunity, not the single individual. In a series of new studies, researchers have determined that ... |

Marine biologists use the terms “marine snow” to depict small aggregates of organic matter, which tend to float around on the surface of liquid water bodies ranging from lakes to oceans. These microscopic structures have in a new study been found to provide a safe heaven, and a shelter, for microorganisms... |

The vast majority of bacteria, microbes and viruses entering our bodies have a very short-lived existence. They are immediately picked up by the immune system, which sends its killer cells to deal with the problem. Only highly-adapted, very tough bugs endure, such as MRSA and HIV. Common ones die off within a few day... |

The immune system is the first and most important line of defense we have against invading pathogens, including bacteria, microbes and viruses. It comprises of many components, but some of the most important are killer cells known as T cells, which are the ones that engulf and digest the invaders, breaking them apart... |

A new scientific research has revealed another hidden ability our immune systems have. The work evidenced the mechanism employed by our body's natural defense mechanism in “learning” the identity of a pathogen, a feature that allows immune cells to respond faster and more effective the next time arou... |

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 ... |

As we pointed out earlier, the state of the “war” between microorganisms and humans is getting increasingly worrying for our species. In spite of being more complex in make-up than bacteria – or maybe because of that –, we cannot adapt very fast to their mutations, and our immune systems just ... |

Perhaps the greatest problem with treatments available today for most conditions is the fact that they address the symptoms and not the root causes of the conditions. Analyzing the interactions of proteins, which occur at very tiny scales, scientists need powerful observational tools. However, not even the most advan... |

Most viruses that are able to infect the human body, as well as other animals, require living cells in order to replicate and create more viral agents. However, they also need specific chemicals and proteins located inside these cells, without which their replication cycle cannot be started. Researchers have, for ins... |
