Which type of immune response does not involve the production of antibodies?

The choice identifying the cell-mediated response as the type of immune response that does not involve the production of antibodies is accurate. The cell-mediated immune response primarily involves the activation of T-cells, which are responsible for directly attacking infected or cancerous cells.

This type of response is crucial for dealing with intracellular pathogens, such as viruses and certain bacteria, that live within host cells where antibodies cannot reach them. Instead of antibodies, the cell-mediated immune response utilizes various cells, including cytotoxic T-cells that recognize and destroy infected cells and helper T-cells that assist in orchestrating the immune response.

In contrast, the humoral response is characterized by the production of antibodies by B-cells in response to antigens. The adaptive response encompasses both humoral and cell-mediated responses, while the passive response pertains to the transfer of antibodies from one individual to another, providing immediate but temporary immunity without the individual's immune system actively producing those antibodies. Thus, it is clear that the cell-mediated response specifically operates through mechanisms that exclude antibody production.
