Any B cell or T cell exhibiting train in opposition to the self — or autoreactivity — is killed all through teaching. Tens of hundreds of thousands of newly created B and T cells are killed each single day because of they fail this teaching course of. If these self-reactive cells escape destruction, they may flip in opposition to the physique and carry out an inappropriate autoimmune assault.
My evaluation investigates how B cells are ready to slide earlier the checkpoints the immune system has in place to guard in opposition to autoreactivity.
