Question

Antigen-antibody reactions are suppressed

• A. In liver dysfunction
• B. In chronic inflammatory reactions
• C. By ACTH
• D. By vitamin K

Answer 1

The correct option is B In chronic inflammatory reactions

Antigen-antibody reaction is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction. It is the fundamental reaction in the body by which the body is protected from complex foreign molecules, such as pathogens and their chemical toxins. In the blood, the antigens with high affinity bound by antibodies to form an antigen-antibody complex. The immune complex is then transported to cellular systems where it can be destroyed or deactivated. One basic application is determination of ABO blood group. It is also used as a molecular technique for infection with different pathogens, such as HIV, microbes, and helminth parasites. Antigen-antibody reaction are suppressed in chronic inflammatory reactions.

Therefore, the correct answer is option B.
