The interferons are

Question

Assertion (A): Secondary immune response is quicker and stronger than the primary immune response.
Reason (R): Our body appears to have the memory of the first encounter therefore response to the subsequent encounter with the same pathogen is quick.

Answer 1

The question asks to identify the correct classification of interferons from the given options. Let's analyze each option to determine the correct answer:

Antigen proteins: Antigens are substances that can induce an immune response in the body, particularly the production of antibodies. However, interferons are not classified as antigens. They do not trigger an immune response like antigens do.
Antiviral proteins: Interferons are a group of signaling proteins made and released by host cells in response to the presence of pathogens, such as viruses, bacteria, parasites, or tumor cells. Their main role is to interfere with viral replication within host cells. Thus, interferons are indeed antiviral proteins.
Antibiotic proteins: Antibiotics are used to kill or inhibit the growth of bacteria. They do not apply to interferons, as interferons specifically relate to the viral response, not bacterial infections.
All of these: This option is invalid because interferons are not antigen or antibiotic proteins. They are specifically antiviral in nature.

Based on the above analysis, the correct answer is antiviral proteins.

Conclusion: Interferons are primarily known for their antiviral properties, helping to modulate the immune response against viral infections.
