WebbT Cell Activation. 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. fms friedrich motorsportWebbB lymphocytes have surface antibodies present in them and they secrete antibodies while T lymphocytes do not have surface antibodies in them and they secrete lymphokines.
