← Life Sciences & MedicineIf a novel virus enters the body, which consequence follows from the activation of naïve B lymphocytes?
A)Immediate antibody-mediated virus neutralization
B)Decreased presentation via MHC class II
C)Clonal expansion and antibody production✓
D)Direct cytotoxic killing of infected cells
💡 Explanation
Naïve B lymphocytes, upon encountering their specific antigen, undergo clonal expansion and differentiate into antibody-secreting plasma cells; because this generates a large population of specific antibodies. Therefore, antibody production increases, rather than direct killing or immediate neutralization, which require prior sensitization.
