Putative mechanisms of action of the proposed adjuvants. Pattern recognition receptors (PRRs) allow innate immunity cells to recognize pathogen-associated molecular patterns (PAMPs) of microbes or damage-associated molecular patterns (DAMPs), which are released from injured or dying cells. The PRRs includes Toll-like receptors (TLRs), Nod-like receptors (NLRs), and и C-type lectin receptors (CLRs), which are considered receptors of adjuvants. NLRP3—NLR pyrin domain-containing protein 3.
