A group of investigators from the University of California in Los Angeles (UCLA) announces the discovery of a new mechanism that may lead to the activation of immune system cells called T cells.
Unlike other activation mechanisms, the new one is extremely potent, and brings to life a group of white cells that are v... |

Experts with Richmond, California-based Sangamo BioSciences announced on Sunday, September 18, that they've managed to create a new type of therapy against HIV/AIDS. They say that their new approach will greatly help researchers looking for a way of combating this condition.
What that team did was basically d... |

The worrying conclusions of a new investigation carried out on animal models reveal that the immune system may in fact attack adult cells that have been reprogrammed into stem cells from a mouse' own tissues. This finding may have serious implications for regenerative medicine.
This relatively-new field of re... |

Scientists from the United States announce that they managed to discover one of the main mechanisms through which the human immunodeficiency virus (HIV) acts on the human immune system, weakening it, and making it incapable of fighting future infections.The team found out that the viral agent was causing a specific s... |

Investigators from the Massachusetts Institute of Technology (MIT) recently made an important discovery, when they are able to determine the mechanisms involved in producing larger amounts of long-term memory T cells in the immune system.These particular cells play a critical role in underlying our bodies' immun... |

Healthcare experts have always been puzzled at the fact that a small minority of those people who get infected with the HIV virus do not develop the full disease, AIDS. Investigators have been looking at what mechanisms underlie this resistance, in hopes of replicating them in the lab, and then turning them into drug... |

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... |

In case of an infection, when pathogens pour freely through an open wound inside the body, the immune system must be quick on the spot with its response. Various types of immune cells need to be activated, and all of this must be done within moments of the time when the invading microorganisms were first detected. Fa... |

Autoimmune diseases are among the most dangerous kind in the world. They manifest themselves when the body's own immune system begins to attack the central nervous system (CNS), inflicting severe damage, and eventually leading to death. Multiple sclerosis is one good example. Although the barriers that exist bet... |

One of the most important types of immune-system cells in the human body is the natural killer (NK) cells. They are among the first to respond to an emergency, such as a pathogen infection, by arriving at the scene and immediately beginning to kill off the intruders. Once activated, these little killers stop at nothi... |

Though some think that the Human Immunodeficiency Virus (HIV) cannot be attacked by the immune system at all, this is very wrong, say scientists. As a matter of fact, CD8+ killer T cells attack the virus as soon as it enters the body, even if the infiltrator is in very high concentrations. However, over time, these c... |

Scientists may have found a way to suppress the ability that cancerous cells have, which is to make the immune system think that they are a natural part of the body. Through this method, they avoid being attacked by the killer T lymphocytes that make up the backbone of our immune system. The immune cells are led to b... |
