Which component is NOT part of innate immunity's cellular response?

The cellular response of innate immunity primarily involves immediate and non-specific mechanisms to defend the body against pathogens. This response includes various types of cells, such as phagocytes, which engulf and digest pathogens, natural killer cells that destroy infected or cancerous cells, and macrophages that perform both phagocytosis and release signaling molecules to coordinate the immune response.

Antibodies, on the other hand, are a component of the adaptive immune system, not innate immunity. They are produced by B lymphocytes in response to specific antigens and play a crucial role in targeting and neutralizing pathogens. Antibodies require a longer time to develop compared to the immediate responses seen in innate immunity. Therefore, while antibodies are essential for the overall immune response, they do not form part of the innate immunity's cellular mechanisms, which rely on various types of immune cells to act quickly and broadly against infections.
