PAMP-pathogen -associated molecular patterns: a. Enable lymphocytes to recognize microbes and disrupt them b. Are cystein-rich peptides of leucocytes c. Are recognized by PRR-receptors of innate immunity d. Are proteins on the surface of infected cell

The correct answer is:<br /><br />c. Are recognized by PRR-receptors of innate immunity<br /><br />PAMPs (pathogen-associated molecular patterns) are molecular structures found on the surface of pathogens that are recognized by pattern recognition receptors (PRRs) on cells of the innate immune system. These receptors, such as Toll-like receptors (TLRs), help the immune system to identify and respond to the presence of pathogens.
