Immunity: rapidly responding T cells (Introduction)

Surface receptors on the T cell surfaces are widely dispersed to quickly pick up signals from foreign antigens:

David: Comment: The T cells develop a library of antigen receptors to protect us. This had to be designed early in evolution for life to survive infections. The information is developed and stored in the thymus where T cells are made.

Tony: If what you say is true, the thymus is where we should look to see if there is a method for adding information to a genome, and if so, what the limits are. We know that our immune system learns, so that information must be getting recorded somewhere somehow.

The cells in the Thymus actually change their DNA to add antibodies that react against antigens that have appeared over time so the T cells have the right ammunition.
