Explanation:
Detailed explanation-1: -The innate immune system recognizes microorganisms via a limited number of germline-encoded pattern-recognition receptors (PRRs). This is in contrast to the large repertoire of rearranged receptors utilized by the acquired system. PRRs possess common characteristics.
Detailed explanation-2: -Microbes are detected by pattern recognition receptors (PRRs) expressed in innate immune cells, such as macrophages. The detection of microbes by the PRRs rapidly activates signaling cascades and generates inflammatory responses.
