What are PAMPs?

Pathogen Associated Molecular Patterns (PAMPs) Patterns or shapes of macromolecules present in bacteria, viruses or fungi but not present on host cells. These target macromolecules are essential to the structure and function of the pathogen, and are genetically conserved. They may be glycoproteins, lipopolysaccharides, peptidoglycans, oligonucleotides, terminal mannose residues on complex polysaccharide molecules, etc
