Question

Quizplus · Accepted Answer

Autoimmune diseases occur when the body's immune system attacks its own "home team" cells and tissues, mistaking them for foreign invaders. This can involve both B cells and T cells, and may result in the production of antibodies that target normal host proteins. Option A is incorrect because B cells do not directly recognize other B cells, but rather produce antibodies that recognize specific antigens on other cells or pathogens. Option B is incorrect because helper T cells do not directly bind to infected cells, but rather secrete cytokines that activate other immune cells. Option D is incorrect because antibodies from a virus would not be reactivated in "home team" cells, as this does not make sense from a biological perspective.
