multiple choice question
interferons are secreted by cells infected with which of the following?

viruses

bacteria

Explanation:

Interferons are proteins released by host cells in response to viral infections. They help in the immune response against viruses by inhibiting viral replication and signaling neighboring cells. Bacteria, worms, and fungi trigger different immune responses (e.g., antibacterial, antiparasitic, antifungal) that do not primarily involve interferons.

A. Viruses
