Specifically, two types of lymphocytes are primarily responsible:
* T lymphocytes (T cells): These cells recognize and destroy infected or cancerous cells directly. They also release signaling molecules (cytokines) that help other immune cells.
* B lymphocytes (B cells): These cells produce antibodies, which are proteins that bind to and neutralize pathogens like bacteria and viruses.
While other immune cells contribute to the overall immune response, lymphocytes are the main players in the crucial process of immunological surveillance.
