How to Answer: Clearly articulate the function of interferons, including their role in signaling neighboring cells to heighten their antiviral defenses and activating immune cells like natural killer cells and macrophages. Discussing specific types of interferons (e.g., Type I, Type II, and Type III) and their unique roles can further demonstrate your expertise. Additionally, mentioning any relevant research or practical experience you have with interferons can provide concrete evidence of your proficiency in this area.

Example: “Interferons are crucial in the body’s antiviral defense. They act as signaling proteins that alert neighboring cells to the presence of a virus, effectively putting those cells in an antiviral state. This limits the virus’s ability to replicate and spread.

In my last research project, we were studying the impact of interferons on a novel virus. By introducing interferons to infected cell cultures, we observed a significant reduction in viral replication. This reinforced the importance of interferons as a first line of defense and highlighted potential pathways for therapeutic intervention. It was fascinating to see how manipulating these proteins could influence the course of an infection, and it underscored the importance of continued research in this area.”

23. What are the potential benefits and risks of using viral vectors in gene therapy?

Understanding the potential benefits and risks of using viral vectors in gene therapy goes beyond mere technical knowledge; it speaks to a grasp of ethical considerations, patient safety, and long-term impacts on public health. This question aims to see how well the candidate can balance innovation with caution, ensuring that advancements in gene therapy do not come at the expense of unforeseen consequences. It also reveals their ability to communicate complex scientific concepts in a way that can be understood by stakeholders, such as regulatory bodies, funding agencies, and even patients.

How to Answer: Detail both the scientific and ethical dimensions. Discuss the benefits, such as the potential for curing genetic disorders and the specificity of viral vectors in targeting cells. Then, pivot to the risks, including possible immune responses, insertional mutagenesis, and long-term effects that are not yet fully understood. Conclude by emphasizing the importance of rigorous clinical trials and ongoing monitoring to mitigate these risks.

Example: “Viral vectors hold immense potential in gene therapy because they can effectively deliver genetic material into target cells, which can correct or compensate for defective genes. They are highly efficient at transduction, meaning they can introduce new genes into cells with high precision. This can lead to significant therapeutic benefits for diseases like cystic fibrosis, muscular dystrophy, and certain forms of cancer.

However, the risks cannot be overlooked. One major concern is the potential for an immune response. The body might recognize the viral vector as a foreign invader and mount an immune reaction, which can reduce the efficacy of the therapy and pose safety concerns. There’s also the risk of insertional mutagenesis, where the insertion of new genetic material could disrupt essential genes or activate oncogenes, potentially leading to cancer. Balancing these benefits and risks requires rigorous preclinical studies, careful patient selection, and ongoing monitoring to ensure the safety and efficacy of the treatment.”
