Sometimes your immune system is not able to activate itself quickly enough to outpace the reproductive rate of a certain bacteria, or the bacteria is producing a toxin so quickly that it will cause permanent damage before the immune system can eliminate the bacteria. In these cases it would be...
There are several types of T cells that can be activated at different times after an infection, each with a different specialized job. Two major types of T cells are helper T (Th) cells and cytotoxic T cells. Th cells act as crucial mediators to activate other cells, including cytotoxic T...
The antigenic MHC-I molecules remain stable for several days. During this time, their purpose is to activate immature (naïve) T cells and transform them into potent killer cells (cytotoxic T cells). Thanks to this "armoring function," dendritic cells constitute a ray of hope for personalized...
the adaptive immune system wouldn’t have to start from scratch. And that’s just they way it works. These “leftover” B and T cells are called memory cells, and in addition to being more numerous than the original, inexperienced B and T cells, memory cells are easier to activate. As...

Insults to the body, from the outside or from the inside, activate the cells of the innate immune system. The immune response transmits this information to the brain to cause physiological and behavioral responses. A mild inflammatory response – such as a low-grade infection, trauma (such as...
