Activated B cells produce antibodies

|
Activated B cells destroy cancer cells.
|
Detailed explanation-1: -While B-cells produce antibodies to fight infection, T-cells protect people from getting infected by destroying cancerous and infected cells. B-cells are also far more likely than T-cells to mutate into a liquid cancer such as chronic lymphocytic leukemia (CLL) or B-cell lymphoma.
Detailed explanation-2: -The correct answer is option 4. B cells and T cells are the main types of lymphocytes. B cells work chiefly by secreting substances called antibodies into the body’s fluids. Antibodies ambush antigens circulating the bloodstream.
Detailed explanation-3: -B cells create antibodies. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection. B cells can also recruit other cells to help destroy an infected cell.
Detailed explanation-4: -Activated in germinal centers of tertiary lymphoid structures, B cells can directly present tumor-associated antigens to T cells or produce antibodies that increase antigen presentation to T cells or kill tumor cells, resulting in a beneficial clinical impact.
