T Lymphocytes

Meaning

T Lymphocytes, or T cells, are a critical subset of white blood cells that constitute the cellular arm of the adaptive immune system, playing a central role in cell-mediated immunity. These immune cells are responsible for directly killing infected or cancerous cells, as well as coordinating the overall immune response through the secretion of signaling molecules called cytokines. In endocrinology, T cells are implicated in autoimmune disorders where they mistakenly target and destroy hormone-producing cells within endocrine glands.
