Quizplus · Accepted Answer

T lymphocytes (T cells) are lymphocytes that migrate from the red bone marrow to the thymus gland where they mature. Several classes of T cells, based on their function, include the following: T_Helper cells are important for nonspecific defense and specific immunity by recognizing foreign pathogens and activating the cells to fight them. T_Cytotoxic cells directly kill cells infected by viruses and cancer cells in specific immunity. T_Memory cells are also used in specific immunity. They remember pathogens that have been introduced to the body so that repeat exposure can be fought more swiftly. T_Regulatorycells suppress an immune response by inhibiting multiplication and chemical secretions from other T cells. T_Regs are important in limiting and preventing autoimmune responses.
