Polymorphisms in Toll-like receptors 2 and 4 genes and their expression in chronic suppurative otitis media

Certain polymorphisms in TLR genes could be indicative for susceptibility to chronic otitis media. Expression of TLR 2 and 4 on middle ear mucosa was more dependable on different types of mucosal changes and type of CSOM than on bacteria found in the specimens. This can indicate that the type of mucosal changes are closely correlated with TLRs activity in middle ear.
