Question

State whether the following statement is true or false.

Interferons are produced in response to antigens.

Answer 1

This statement is false.

Explanation:

Interferons are virus-induced proteins produced by cells that are infected with viruses, not specifically in response to antigens. They are part of the body’s first line of defense against viral infections and interfere with viral replication. The production of interferons is triggered mainly by viral invasion and certain stimuli such as inactivated viruses, double-stranded RNA, or bacterial endotoxins. They are not produced as a direct response to antigens, which typically stimulate the production of antibodies by the immune system.
