@doctorjaybe: How do immune cells in innate immunity detect problems? Unlike adaptive immunity, which remembers specific antigens, innate immune cells don't have memory. Instead, they recognize common patterns associated with danger. These include: PAMPs (Pathogen-Associated Molecular Patterns) found on microbes DAMPs (Damage-Associated Molecular Patterns) released from injured or dying cells Cells like dendritic cells and macrophages use pattern recognition receptors (PRRs), such as Toll-like receptors (TLRs), to detect these signals and trigger an immediate immune response #innateimmunity #dendriticcell #macrophage #medicalmemes #medschool
