UNDERSTANDING THE PATHOGEN-ASSOCIATED MOLECULAR PATTERNS (PAMPs) AND PATTERN RECOGNITION MOLECULES (PRMs)
Pathogen-associated molecular patterns (PAMPs) are structural components common to a particular group of pathogen or infectious disease agents. PAMPs are often macromolecules and include polysaccharides, […]
