Question

What is neutralization in the context of the immune response?

a) Aggregation or clumping of cells or particles.
b) Assembly of large antigen-antibody complexes that precipitate from solution.
c) Blocking of structures on microbes and toxins.
d) Increased phagocytic uptake of cells or molecules.
e) Complement activation initiated by antibody attachment.

Answer 1

Neutralization in the context of the immune response is the process where specific antibodies bind to antigens on pathogens, blocking their attachment to cells and preventing infection.

Step-by-step explanation:

In the context of the immune response, neutralization refers to the blocking of structures on microbes and toxins, effectively preventing them from attaching to cells. It involves the binding of specific antibodies to antigens found on the surface of pathogens, such as viruses, bacteria, or toxins. An example of this process includes Secretory IgA, which can bind to pathogens on the intestinal mucosa, blocking their ability to attach and initiate infection. This mechanism plays a crucial role in protecting against the infiltration and spread of infectious agents.
