<prompt> All of the following are pattern recognition receptors for extracellularingested microbes, except:Toll-like receptors TLRsKiller-cell immunoglobulin receptors KIRsNOD-like receptors NLRsC-type lectin receptors CLRs  <response>: Pattern recognition receptors Cells that paicipate in innate immunity are capable of recognizing ceain components that are shared among related microbes. Pattern recognition receptors are located in all cellular compaments where microbes may be present: plasma membrane receptors detect extracellular microbes, eg. Toll-like receptors TLRs, C-type lectin receptors CLRs. endosomal receptors detect ingested microbes, eg. Toll-like receptors TLRs cytosolic receptors detect microbes in the cytoplasm, eg. NOD-like receptors NLRs, RIG-like receptors RLRs Killer-cell immunoglobulin-like receptors KIRs, are present on plasma membrane of NK cells. KIR receptors can recognise major histocompatibility MHC class I variants, which allows NK cells to detect virally infected cells or transformed cells.
