Solution

The potential outcomes following complement activation include:

  1. Opsonization of pathogens for phagocytosis: The complement system tags pathogens for destruction by phagocytes, a process known as opsonization.

  2. Cytolysis of pathogens through formation of the membrane attack complex (MAC): The complement system can directly kill pathogens by forming a pore-like structure (MAC) in the pathogen's cell membrane, leading to cytolysis.

  3. Induction of an inflammatory response: The complement system can trigger an inflammatory response, which helps to recruit immune cells to the site of infection and promotes healing.

The other options are not typically outcomes of complement activation:

  • Generation of antimicrobial peptides: While these are an important part of the immune response, they are not typically produced as a result of complement activation.

  • Apoptosis of virus-infected cells: This is usually mediated by cytotoxic T cells, not the complement system.

  • Induction of a memory response by B and T cells: This is a feature of the adaptive immune response, not the complement system, which is part of the innate immune response.
