Question

Quizplus · Accepted Answer

Only interferons (IFNs) are produced and released by virally infected cells in response to viral double-stranded ribonucleic acid (RNA). IFN-a and IFN-b induce the production of antiviral proteins, thereby conferring protection on uninfected cells. IFN-a or IFN-b is released from virally infected cells and attaches to a receptor on a neighboring cell. IFNs also enhance the efficiency of developing an acquired immune response. IL-1 is a proinflammatory interleukin. IL-10 plays a critical role in wound healing. TNF has several systemic effects but is not released from virally infected host cells.
