Pattern Recognition Receptors

The video tutorial explores pattern recognition receptors (PRRs) in the immune system, focusing on how they detect pathogens and tissue damage through PAMPs and DAMPs. It discusses the importance of receptor location, the structure and function of Toll-like receptors (TLRs), and the roles of NOD-like receptors (NLRs) and Rig-I-like helicases in pathogen detection. The tutorial also covers DAMP receptors and their role in pro-inflammatory signaling, highlighting the innate immune system's rapid response capabilities.
