Variola virus, the causative agent of small pox, produces soluble TNF receptors. What advantage does the production of a TNF receptor have for avoiding immune response?
A. TNF represents a family of soluble cytokines. By producing soluble receptors that bind cytokines, then the cytokine effector response is eliminated and only a limited immune response will occur.
B. TNF receptors bind to cells of the immune system and prevent the release of cytokines.
C. TNF receptors block transcription within infected cells so that new virus particles cannot be made.
D. TNF receptors bind to TC cells, preventing lysis of infected cells.
E. TNF receptors allow an infected cell to become infected by more than one variola virion (virus particle).
