Question

Quizplus · Accepted Answer

PAMPs (pathogen-associated molecular patterns) can be found on the surface of foreign substances, such as bacteria, and act as signals to attract phagocytes to the site of infection. This helps to initiate the immune response and clear the infection. IFNs (interferons) are cytokines that are produced in response to viral infections, but they do not directly attract phagocytes. BALTs (bronchus-associated lymphoid tissue), RES (reticuloendothelial system), and MALTs (mucosa-associated lymphoid tissue) are types of lymphoid tissue found in various organs and tissues, but they do not directly attract phagocytes to foreign substances.
