The interferon system: an overview
WebThe interferon system is the first line of defense against viral infection in mammals. This system is designed to block the spread of virus infection in the body, sometimes at the expense of accelerating the death of the infected cells. As expected of potent cytokines, in addition to their antiviral effects, interferons have profound effects on ... WebTLRs have also been identified in the mammalian nervous system. Figure 23.2. The characteristics and location of cells involved in the innate immune system are described. (credit: modification of work by NIH) Figure 23.3.
