Innate responses act both to mediate defense during periods of development of, and to direct the quality and nature of, downstream adaptive immune responses. The type 1 interferons, interferons alpha and beta (IFN-伪/尾), induced at early times during viral infections, are examples of innate ...

Examples include the body's complement system and substances called interferon and interleukin-1 (which causes fever). If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system.ʺ And, finally cellular barriers comprise various cells which attach ...
In the innate immune response,pattern recognition receptors (PRRs)are engaged to detect specific viral components such as viral RNA or DNA or viral intermediate products and to induce type I interferons (IFNs) and other pro-inflammatory cytokines in the infected cells and other immune cells. Does...
After a priming dose of bacteria, some insects exhibit a prolonged activation of the immune response that nonspecifically protects against subsequent challenges. In some cases, microbial challenge of mothers results in the production of more resistant offspring. In addition to these two examples of ...

While multiple sclerosis (MS) is often quoted as one of the most striking examples of an inflammatory neurodegenerative condition, it is now widely recognized that inflammatory processes, particularly the innate immune responses, play a crucial role also in the pathogenesis of several other ...

infections. Although the causal importance of a relative LT deficiency in such susceptibility remains to be established, it is possible that defects in LT synthesis represent a common pathway to impaired innate immunity. As examples of this phenomenon, HIV infection and malnutrition will be considered...
