Question

Quizplus · Accepted Answer

Interferons are a group of proteins produced by host cells in response to the presence of viruses. They can interfere with viral replication by inducing the expression of antiviral proteins, inhibiting translation of viral proteins, and promoting the degradation of viral RNA. Streptolysin and leukocidin are toxins produced by some bacteria, while histamine is a molecule involved in allergic reactions and inflammation.
