The immune system must be able to quickly attack invaders like viruses, while also ignoring harmless stimuli, or allergies can result. Immune cells are known to ignore or "tolerate" molecules ...

Class-switched memory B cells, which are a major component of the immune system, have undergone a process known as ‘class-switching’ that makes them highly efficient at fighting infections that the ...

Our immune systems weaken as we get older, making fewer cells that fight infection and help us recover from illness and injury. Scientists aren't completely sure why. They may have a better idea ...

Not only does this tissue protect these key components of our nervous system, but just a few years ago, it was discovered that they also hold a concentration of T-regulatory immune cells (T-regs).

Their findings revealed novel mechanisms: the immune system amplifies its defense cells in a far more targeted way than previously believed. T-cells proliferate and specialize during the immune ...

Immunotherapies target T cell activation to redirect the immune system to pathogens that fall under the radar. Although T cells are well studied and used to treat illness, they can also become ...
