During a viral infection, the immune response involves sequential changes in the levels of various factors. If we plot the changing titers of Interferon α/β, Natural Killer cells (NK cells), and virus-specific Cytotoxic T-Lymphocytes (CTLs) over time, which of the following correctly identifies the order of their peak levels (from earliest to latest)?
- 1A: Interferon; B: virus-specific CTLs; C: NK cells
- 2A: NK cells; B: Interferon; C: virus-specific CTLs
- 3A: Interferon; B: NK cells; C: virus-specific CTLs✓
- 4A: virus-specific CTLs; B: Interferon; C: NK cells
Correct answer
A: Interferon; B: NK cells; C: virus-specific CTLs
