The correct Answer is:
To solve the question regarding interferons and identify the incorrect statement, let's analyze each option step by step. ### Step 1: Analyze Option A **Statement:** Synthesized by uninfected host cells that are susceptible to viral infection. **Analysis:** Interferons are actually produced by virus-infected cells, not uninfected cells. The primary role of interferons is to alert neighboring cells to the presence of a virus, thereby enhancing their antiviral defenses. Therefore, this statement is incorrect. ### Step 2: Analyze Option B **Statement:** They can be used to destroy the tumor. **Analysis:** Interferons have been shown to have anti-tumor properties and can be used in cancer therapies. They help in modulating the immune response and can inhibit tumor growth. Thus, this statement is correct. ### Step 3: Analyze Option C **Statement:** α-interferons are secreted by virus-infected cells. **Analysis:** Alpha interferons (α-interferons) are indeed produced by cells that have been infected by viruses. They play a crucial role in the immune response against viral infections. Therefore, this statement is correct. ### Step 4: Analyze Option D **Statement:** They are categorized under cytokine barrier of innate immunity. **Analysis:** Interferons are classified as cytokines and are part of the innate immune response. They help in the defense against viral infections and are considered a key component of the cytokine barrier. Thus, this statement is correct. ### Conclusion After analyzing all the options, the incorrect statement regarding interferons is: **Final Answer:** (a) Synthesized by uninfected host cells that are susceptible to viral infection. ---
