Detailed explanation-1: -The major difference between humoral and cell-mediated immunity is that humoral immunity produces antigen-specific antibodies, whereas cell-mediated immunity does not.

Detailed explanation-2: -The main types of lymphocytes involved in cell-mediated immunity include naïve T cells, helper T cells, killer T cells, and macrophages.

Detailed explanation-3: -Cell-mediated immunity (CMI) is an immune response that does not involve antibodies but rather involves the activation of macrophages and NK-cells, the production of antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

Detailed explanation-4: -Macrophages confer innate immunity, which is typically the first line of defense against foreign antigens. Adaptive immunity, on the other hand, is the subtype of the immune system that involves specialized immune cells and antibodies.
