Verified step by step guidance

Understand the role of interferons: Interferons are proteins produced by the body's cells as a response to viral infections. They help inhibit viral replication and modulate the immune system.

Identify conditions treated by interferons: Interferons are commonly used in the treatment of viral infections, such as hepatitis C, and certain types of cancer due to their ability to enhance the immune response.

Recognize the exception: Muscular dystrophy is a genetic disorder characterized by progressive muscle degeneration and weakness. It is not caused by viral infections and does not involve the immune system in the same way as viral infections or cancer.

Consider the mechanism of action: Since interferons work by targeting viral replication and modulating immune responses, they are not suitable for treating muscular dystrophy, which is not related to viral activity.

Conclude the exception: Based on the understanding of interferons' function and the nature of muscular dystrophy, it is clear that muscular dystrophy is the condition that cannot be treated with interferons.
