Viral PAMPs and related cellular PRRs. Viral glycoproteins may be recognized by TLR2/4 or CLRs on the cell surface. In the intracellular environment, various viral RNA and DNA structures are recognized by nucleotide sensors localized in endosomes or in the cytoplasm. It remains unknown whether nuclear PRRs exist able to recognize viral PAMPs in the nucleus.
