The Immune System - Recognition in innate immunity. How?

... from multiple genes by very complex mechanisms of recombination and mutation. The components of the innate immunity (e.g. Toll-like receptor on macrophages, mannose-binding lectin in the plasma) have their specificity encoded on a genomic level, are expressed in similar form on the surface of ...
