Interferons ________.
A) are routinely used in nasal sprays for the common cold
B) are virus-specific, so that an interferon produced against one virus could not protect cells against another virus
C) act by increasing the rate of cell division
D) interfere with viral replication within cells

Question

Quizplus · Accepted Answer

Interferons interfere with viral replication within cells by inducing a state of viral resistance. They do not increase the rate of cell division and are not virus-specific, as they induce antiviral activity against a broad range of viruses. While interferons have been studied as a potential therapy for the common cold, they are not routinely used in nasal sprays for this purpose.
