  • The researchers carried out the study to better understand how the amount of antigen controls how the TCR sends messages to the T cells' command centre, and how this affects the type of immune response. (birmingham.ac.uk)
  • They wanted to explore how antigen amounts control the expression of so-called 'immune checkpoints' that act as brakes on immune responses. (birmingham.ac.uk)
  • When we exposed T cells to the highest amounts of antigen, they stopped sending signals to their command centre, and this was because they had increased the number of immune brakes, which shut down the messengers. (birmingham.ac.uk)
