Regulation of lymphocyte activation

Regulation of lymphocyte activation involves controlling how immune cells called lymphocytes respond to threats like infections. This process ensures the immune system reacts effectively without overreacting, which could damage the body. Activation requires signals from other immune cells, but this process is tightly controlled by various molecules that can enhance or suppress responses. These regulatory mechanisms maintain immune balance, promoting defense against pathogens while preventing autoimmune reactions where the body attacks itself. Thus, lymphocyte activation regulation is essential for a healthy immune response, balancing protection with self-tolerance.
