T lymphocytes relate to which adaptive immunity?

T lymphocytes are the main players in a branch of adaptive immunity known as cell-mediated immunity. They don’t produce antibodies themselves; instead, they directly attack infected cells and orchestrate other immune responses through cytokines. Cytotoxic T cells (CD8+) kill cells harboring intracellular pathogens, while helper T cells (CD4+) coordinate the response by activating macrophages and helping B cells later on. This contrasts with humoral immunity, which relies on B cells producing antibodies that circulate to neutralize pathogens. Innate immunity is non-specific and does not depend on T cells, and autoimmunity is a disease process where the immune system attacks self-t tissues, not a type of adaptive immunity. So T lymphocytes relate to cell-mediated immunity.
