These receptors are able to recognize special glycoproteins, which are only
found on bacteria cell. They are in fact not really antigen- or epitop-
specific like an antibody, but they are really able to recognize bacteria
cell (An antibody doesn't have this ability!!!) So you can say that these
receptors are bacterial-specific. The second thing is, that these recoptor
does trigger the expression of second signals like B7.1 or B7.2 (CD80,
CD86), which are needed for an activation at the antigen-presentation
process.
You can read a new publication in nature about Toll-like receptor 5 - Nature
2001 Apr 26;410:1099-103.
You can also look in the Medline after review-articles from Janeway C Jr. He
invented the word PAMP and you will find articles about innate immune
recognition. I have read all that stuff but I have forgotten many of them
