WebIntroduction. Innate immunity against RNA viruses involves pattern recognition receptors (PRRs) that recognize structurally conserved molecules from diverse pathogens known as pathogen-associated molecular patterns (PAMPs) (Arpaia & Barton, 2011).PRRs include TLRs (particularly TLR3, TLR7 and TLR8) and members of the cytosolic retinoic acid … WebAll TLRs except TLR3 use a signaling protein called MyD88 (myeloid differentiation primary response protein 88), a protein that allows the innate immune cell to function normally.
