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... |

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... |
