Developing Lymphocytes – an extra credit question for micro

29 Apr

Both B and T Cells express surface antigen receptors, the B Cell Receptor (BCR) and T Cell Receptor (TCR), respectively. During development each of these kinds of immature lymphocytes will express early versions of these receptors on their surface (Pre-BCR and Pre-TCR).

What is the purpose of expressing these receptors long before they will ever come into contact with antigens?

answer quickly – the first correct (and complete) answer gets 3 pts extra credit on the upcoming exam!

    They express these early to see if they bind to self.

    Because antigen receptors are randomized and may be unstable. This step ensures that the receptor is stably expressed. 🙂
