A collection of cell types that provide protection against various antigens.
Immunity mediated by the T lymphocytes. (T cells, cells originating from the thymus.)
T-cell- mediated immune functions requiring cell interactions (e.g., graft rejection or destruction of infected cells).
The immune system component that directly targets and eliminates harmful cells without relying on antibodies, which are proteins generated to combat infections.
Lymphocytes, a specific type of white blood cells, initiate a response against infectious organisms and abnormal cells like cancer cells. There are two primary types: T-lymphocytes, which offer cellular immunity, and B-lymphocytes, which generate antibodies. T-lymphocytes recognize specific antigens, including cancer cells and virus-infected cells, considering them foreign substances. Within the T-lymphocyte group, there are killer T-cells that bind to abnormal cells and release toxic proteins, effectively destroying them.
