Question

Which mechanism describes the cellular immune response?

पर्याय

• Trapping of antigens in lymph nodes to trigger localised responses

• Filtration of blood-borne antigens by the spleen

• Direct cooperation of lymphocytes and macrophages to destroy pathogenic organisms without antibody production

• Production of antibodies by B lymphocytes in response to antigens

Answer 1

The cellular immune response relies on direct cooperation of lymphocytes (particularly T cells) and macrophages to destroy pathogenic organisms. Unlike the humoral response, it does not involve circulating antibodies but rather cell-to-cell interactions and direct killing mechanisms.
