When a T cell encounters a recognizable APC, the naïve cell receives a signal to mature. There are three types of signals: TCR, BCR, and cytokine signals. If a cell receives all three signals, it will mature into an effector cell. If a cell only receives one of the signals (TCR or BCR), the cell will become useless.
