Answer:
- Cell mediated immunity uses what type of WBC to attack and kill the infected cell? T-cells
- Helper T or Killer T cells are released that cause the cell to lyse or undergo apoptosis.
Explanation:
White blood cells or leukocytes are integral to cell-mediated immune function in the human body. T cells are produced in bone marrow, and mature in the thymus. They recognize antigens on virus-infected cells and target them for attack; antigens and receptors fit together to allow for identification.
- Helper T cells aid in activating other immune cells, along with eliminating cells infected by pathogens; they release cytokines
- Killer T cells produce special toxins (perforins and then cytotoxins) that lead to cell lysis and programmed cell death or apoptosis.
