The immune system is a remarkably adaptive defence system that has evolved in vertebrates to protect them from invading pathogenic micro-organisms and cancer. It is able to generate an enormous variety of cells and molecules capable of specifically recognising and eliminating an apparently limitless variety of foreign invaders. These cells and molecules act together in an exquisitely adaptable dynamic network, whose complexity rivals that of the immune system. The immune system is able to recognise …showed first 75 words of 4406 total…

It appears that tolerance mechanisms for B cells are very similar to those for ab T cells. immature B cells die or are inactivated when their receptors bind to something. Whether tolerance can be imposed on mature B cells as it can be on mature ab T cells remains to be seen. T cells with gd receptors, however are a
