If a macrophage phagocytizes a bacterium coated with IgG antibodies and complement C3b in the bloodstream, which consequence follows?

💡 Explanation

Phagocytosis mediated by both IgG and complement C3b receptors leads to increased inflammatory cytokine production because it signals a significant threat. Therefore, an inflammatory response is triggered, rather than direct antigen presentation, decreased T-cell activity, or increased ADCC, which are less immediate responses.
