Question

Quizplus · Accepted Answer

Interferons are small proteins that are secreted from virally infected cells to prevent the spread of the infection. They can activate other cells of the immune system, such as natural killer cells and macrophages, to help fight the infection. Mast cells are not directly involved in viral infections, and immunoglobins (also known as antibodies) are not secreted by infected cells but rather produced by B cells in response to an infection.
