Cellular Basis Of Disease: Why has the discovery of Toll-like receptors revolutionised our understanding of how the innate immune system works, and what is the therapeutic potential?

The body has two immune systems: the innate immune system and the adaptive immune system.
Adaptive, or acquired, immunity refers to antigen-specific defence mechanisms that take several days to become protective and are designed to react with and remove a specific antigen. This is immunity develops throughout life.
Innate immunity refers to antigen-nonspecific defence mechanisms that a host uses immediately or within several hours after exposure to an antigen. This is the immunity that you are born with, and is the initial response by the body to eliminate microbes and prevent infection.
It is in the innate immune system that Toll-like receptors are important in helping our understanding.
The most important role of the innate immune system is to react rapidly to infectious agents with the......
